    The NAO climatic phenomenon is the main responsible for the interanual cloud cover variability in Europe. We explore the relationship between the NAO and the solar radiation spatio-temporal variability in Europe during winter. Measured monthly sums of sunshine duration and short-wave downward solar flux reanalysis data have been used. Correlation analysis between the NAO index and the measured sunshine duration shows a maximum positive value (+0.75) over the Iberian Peninsula. Accordingly, solar radiation in this area undergoes an interanual variability that can reach up to 30%, with the derived consequences for a reliable solar energy resources evaluation. (Author)

    Full Text Available A variabilidade da circulação tropical, com ênfase nos sistemas monçônicos, é examinada usando diversas variáveis para o período de 1948-1999. A componente monçônica do potencial de velocidade em 200 hPa (χ-transiente, o desvio da média anual do desvio da média zonal, é o parâmetro chave usado para obter os modos monçônicos. A análise de Funções Ortogonais Empíricas (EOF do χ-transiente fornece dois modos separados. O primeiro modo descreve a variabilidade multi-decenal dos sistemas monçônicos da América do Sul e do Pacífico oeste. Esse modo, chamado monçônico multi-decenal (MMD, ocorre por todo o ano e contém a variabilidade multi-decenal relacionada à dinâmica da Oscilação Decenal do Pacífico (ODP. O segundo modo descreve as variações interanuais opostas entre a Ásia, África e oceano Índico e a região do oeste dos Estados Unidos, México e Pacífico leste. Esse modo, chamado modo interanual (MIA apresenta algumas similaridades com o modo tropical interanual El Niño - Oscilação Sul. Alguns aspectos desses modos, incluindo sua circulação e características termodinâmicas são discutidas aqui. Finalmente, índices baseados nos padrões das configurações espaciais desses modos são construídos. A eficiência desses índices para fins de monitoramento é analisada. Logo, trata-se de um novo aspecto não proposto em trabalhos anteriores.Tropical circulation variability, with emphasis on the monsoon systems is examined using several variables for the 1948-1999 period. The monsoon component in the 200 hPa velocity potential (transient-χ, the deviation from the annual mean of the zonal deviation field, is the key parameter used here to obtain the monsoon modes. The Empirical Orthogonal Function (EOF analysis of the transient-χ yields two separate modes. The first mode describes the multi-decadal variability of the monsoon systems in South America and in the western Pacific. This mode, called the multi

Del total de 332 muestras de ¾Chl-a, 198/134 se obtuvieron en condiciones de surgencia activa/relajada, de las cuales 24/38 y 30/36 muestras estuvieron asociadas con al menos dos fases frías/cálidas, de los tres ciclos ambientales (condiciones ambientales "fría"/"cálida" respectivamente. Los menores valores de ¾Chl-a durante las condiciones ambientales "frías" y "cálidas" respecto de las "neutras" alcanzaron significancia estadística tanto en surgencia activa como relajada (144/60 muestras respectivamente. Una mayor mezcla turbulenta durante condiciones ambientales "frías" y una nutriclina más profunda durante las "cálidas" explicarían los menores valores de ¾Chl-a. Datos de clorofila

Se describen también los cambios entre los períodos 1981-2000 y 1961-1980 en la variabilidad diaria, en la interanual y en los extremos (percentiles 75 y 25 de TX y TN. El patrón geográfico de los cambios entre los dos períodos de la variabilidad diaria de TX y TN es similar al patrón geográfico de los cambios en los extremos de estas variables. Sobre la Argentina en general se encuentra una disminución en la frecuencia de días calurosos en verano y de noches frías en invierno consistente con una disminución en la variabilidad diaria. La máxima variabilidad interanual de TX se da en una zona de transición que incluye gran parte del centro y norte argentino, donde la humedad del suelo regula la variabilidad de la evapotranspiración dando lugar a feedbacks con la atmósfera. Los cambios entre los dos períodos sugieren un corrimiento hacia el sudoeste en la zona de máxima variabilidad interanual de TX en la climatología observacional posiblemente asociado con cambios en la variabilidad de la precipitación. En general los reanálisis tienen dificultades para capturar los principales patrones geográficos de los cambios de la variabilidad diaria e interanual de TX y TN entre los dos períodos

Sin embargo, la influencia de los cambios ontogenéticos en la membresía gremial sobre la estructura espacio-temporal de los ensambles de peces permanece virtualmente desconocida. En este trabajo estudiamos la variabilidad espacio-temporal en la estructura de los gremios alimenticios ontogenéticos (OFG de los ensambles de peces intermareales que ocurren en el intermareal rocoso de la costa de Chile central. Para esto realizamos an��lisis de componentes principales (PCA y pruebas de aleatorización (pruebas R de la composición relativa de las OFG de estos ensambles, obtenidos de muestreos estacionales en diez pozas intermareales ubicadas en dos alturas de mareas en la zona intermareal en tres localidades entre los 33° y 34° S. En general, los PCA y pruebas R sugieren que la variabilidad espacial domina sobre la variabilidad temporal en la estructura de las OFG, debido principalmente a la alta representatividad de las especies omnívoras en las pozas altas del intermareal en dos de las tres localidades muestreadas. Sin embargo, cambios relacionados a la fenología en la representación de las clases de tamaño de los peces (i.e. reclutamiento de carnívoros en primavera-verano junto con diferencias ontogenéticas en la selección de hábitat (e.g., selección por pozas del intermareal bajo por la OFG de carnívoros de gran tamaño contribuyeron a una diferenciación espacial y temporal de la estructura de la OFG. Finalmente, la representación relativa de cada OFG se correlacionó con la de sus especies dominantes, sin evidencia de una compensación por densidad. Esto sugiere bajos niveles de redundancia funcional entre las especies en cada OFG, lo cual denota la vulnerabilidad del funcionamiento de estos ensambles a perturbaciones sesgadas en tamaño corporal tales como la pesca.

    Chile is a long (2650 miles), narrow (250 miles at widest point) country sandwiched between the Andes mountains and the Pacific. The northern desert is rich in copper and nitrates; the temperate middle region is agricultural and supports the major cities, including Santiago, the capital, and the port of Valparaiso; and the southern region is a cold and damp area of forests, grasslands, lakes, and fjords. The country is divided into 12 administrative regions. Chile's population of 12.5 million are mainly of Spanish or Indian descent or mestizos. Literacy is 92.3%, and the national language is Spanish. Infant mortality is 18.1/1000, and life expectancy is 68.2 years. 82% of the people are urban, and most are Roman Catholics. Chile was settled by the Spanish in 1541 and attached to the Viceroyalty of Peru. Independence was won in 1818 under the leadership of Bernardo O'Higgins. In the 1880s Chile extended its sovereignty over the Strait of Magellan in the south and areas of southern Peru and Bolivia in the north. An officially parliamentary government, elected by universal suffrage, drifted into oligarchy and finally into a military dictatorship under Carlos Ibanez in 1924. Constitutional government was restored in 1932. The Christian Democratic government of Eduardo Frei (1964-70) inaugurated major reforms, including land redistribution, education, and far-reaching social and economic policies. A Marxist government under Salvador Allende lasted from 1970 to 1973 when the present military government of General Pinochet Ugarte took power, overthrew Allende, abolished the Congress, and banned political parties. It has moved the country in the direction of a free market economy but at the cost of systematic violations of human rights. A new constitution was promulgated in 1981, and congressional elections have been scheduled for October, 1989. A "National Accord for Transition to Full Democracy" was mediated by the Catholic Church in 1985. The social reforms of the

Durante el periodo de estudio, se recolectó un total de 44.606 huevos de peces y 2.016 larvas correspondientes a 28 taxa. Los estados tempranos de peces pelágicos pequeños dominaron en las muestras, con densidades de ~ 14.000 huevos 10 m-2 de anchoveta (Engraulis ringens y > 100 larvas 10 m-2 de clupeidos. Análisis multivariados indicaron la formación de dos grupos de estaciones, uno asociado a la zona de fiordos, de mayor profundidad, con fuertes gradientes verticales de temperatura y salinidad y mayor estratificación, y otro grupo asociado al borde oriental de la isla Chiloé, de menor profundidad y mayor mezcla en la columna de agua. En las zonas de mayor estratificación (Le., mayor frecuencia de Brunt-Váisála, N-2, se encontraron mayores densidades de huevos y larvas de peces pelágicos y mesopelágicos (Strangomera bentincki y Maurolicus parvipinnis. Al comparar esta información con un crucero oceanógrafico llevado a cabo 10 años antes en la misma zona (octubre de 1995, se detectaron cambios en la composición específica de ictioplancton, lo que puede indicar diferencias en las especies de peces marinos que utilizan la zona de fiordos y canales como área de desove y crianza larval.The distribution and abundance of ichthyoplankton from southern Chile (41-45°S during November 2005 were analyzed, in relation to the oceanographic features of the water column (temperature, salinity, stratification.

    Full Text Available El género Alstroemeria es exclusivamente sudamericano y consta de 82 taxa distribuyéndose, principalmente en Chile y Brasil. La gran importancia económica que han adquirido las Alstroemerias chilenas como plantas ornamentales ha despertado gran interés en la variabilidad morfológica de las flores y variabilidad genética en especies con potencial valor económico. Una de ellas es Alstroemeria hookeri que posee cuatro subespecies, de las cuales, la subespecie tipo, es endémica de las regiones del Maule y Biobio. Su distribución geográfica consiste de dos rangos, separados por la Cordillera de la Costa. Así, existen poblaciones costeras, creciendo, entre los 5-20 m de altura en las provincias de Arauco, Concepción, Nuble y Cauquenes y poblaciones del interior creciendo entre los 100-150 m de altura, en las provincias de Biobio y Nuble. Evidencias preliminares señalan diferencias fenotípicas entre poblaciones costeras y del interior, relacionadas con el color y forma de los tépalos. Por esta razón, se realizó un estudio morfológico comparativo en el rango completo de distribución de esta subespecie y estudiar su genética poblacional, especialmente los niveles de estructuración poblacional. Se analizaron 33 caracteres florales, mediante métodos de ordenación. El estudio morfológico indica una tendencia a separar las poblaciones en dos grupos, coincidiendo con los extremos de la variación morfológica y con ambos rangos de distribución, existiendo caracteres que aportan a ello. Los índices de variabilidad genética fueron determinados usando 17 loci aloenzimáticos. Además, se estimaron los valores de estructuración poblacional y se realizó un análisis de AMOVA. Se estimaron valores de distancia genética de Nei, entre todos los pares de poblaciones para construir un dendrograma que refleje las relaciones de similitud genética. Los resultados indican altos valores de estructuración entre poblaciones y baja variabilidad

Resultados: El IA registró el año 2012 un máximo interanual de 0,61; durante el período enero-marzo disminuyó a 0,30; abril-agosto aumentó a 0,75 y setiembrediciembre disminuyó a 0,43. En cambio, el EOA reportó en el 2005 un máximo interanual de 0,22; en el período abril-junio disminuyó a 0,09; juliosetiembre aumentó a 0,30; octubre-diciembre disminuyó a 0,22, y enero-marzo aumentó a 0,20. El análisis estadístico reportó un coeficiente de correlación entre el IA del sensor OMI y el EOA del sensor MODIS de las plataformas Aqua y Terra, siendo 0,1041 y 0,0982 (p<0,05, respectivamente. La misma correlación fue efectuada entre los datos del sensor MODIS, resultando más elevada 0,902 (p<0,05. El IA mostró una tendencia de incremento a razón de 0,036/año; el EOA de disminución, 0,003/año. Conclusiones: Se identificó un patrón de variación significativo entre las estaciones y los meses de ambos parámetros con elevados valores del IA en invierno y otoño, máximos en agosto; el EOA, en primavera y verano, máximos en septiembre.

    Full Text Available Entre junio de 2002 y abril de 2003 se midió el contenido de cadmio total y disuelto entre la superficie y los 100 m de profundidad, en dos estaciones localizadas en la bahía Mejillones del Sur. El rango de cadmio total y cadmio disuelto en las aguas de esta bahía fue 0,41-10,7 y 0,08-1,61 nM, respectivamente, durante el período de muestreo. Los resultados fueron correlacionados con la estructura físico-química de la columna de agua al momento del muestreo, de manera de estudiar los patrones de variabilidad estacional de este metal en este sistema de surgencia. Las condiciones oceanográficas imperantes durante este período correspondieron a un año normal (no-El Niño. Las masas de agua presentes en la bahía correspondieron a agua subantártica, subtropical y ecuatorial subsuperficial, con diferentes grados de mezcla y estratificación durante el período de estudio. Los perfiles de cadmio presentaron una distribución vertical clásica de un micronutriente. Sin embargo estos perfiles presentaron leves diferencias que pueden ser atribuidas a la condición de mezcla de las masas de agua al interior de la bahía. Un análisis multivariado de los parámetros registrados indicó que la variación temporal de cadmio en las aguas superficiales está asociada a las fluctuaciones de la clorofila a y la temperatura. Esto sugiere que, a escala estacional, la producción de biomasa fitoplanctónica sería el principal factor que controla la distribución de cadmio en esta bahía. Por otro lado, a pesar de que el cadmio es un metal redox sensitivo no se encontró un efecto significativo de la disponibilidad de oxígeno sobre el comportamiento de este metal, de manera que la condición micróxica de las aguas de fondo de la bahía no sería un factor preponderante en el flujo de cadmio hacia los sedimentos. La razón Cd/PO4 encontrada en Mejillones es similar a la reportada en otras zonas costeras de Chile. Los bajos valores y la tendencia temporal

    Full Text Available The eastern boundary of the Chile-Peru Current System constitutes one of the most biologically productive ecosystems in the world, due largely to coastal upwelling and the horizontal advection of nutrients. In this ecosystem, El Niño events are of great importance in the interannual variability of the environment. A change was observed in the environmental regime at the beginning of the 1970s with the onset of the 1972-1973 El Niño, marking an important decrease in the anchovy fishery (Engraulis ringens. After the mid-1970s, sardine (Sardinops sagax landings increased noticeably. A second regime shift at the end of the 1980s was seen mostly in the noticeable recovery of anchovy and the decline of sardine. Herein, we present an integrated conceptual model of the different local and large-scale phenomena that affect the marine environment off northern Chile and the distribution and abundance of pelagic resources. The model considers an analysis of environmental and bio-fishery data on different scales and describes how the interdecadal (associated with re-gime shifts and interannual (associated with El Niño events fluctuations in the Equatorial Pacific are mani-fested in the eastern South Pacific and, therefore, in the northern zone off Chile, affecting the annual eyele, the dynamic of the coastal trapped waves, and coastal upwelling. In this framework, interdecadal fluctuations play an important role in the anchovy-sardine-anchovy replacement sequence.El borde oriental del Sistema de Corrientes de Chile-Perú constituye uno de los ecosistemas de mayor productividad biológica del mundo, debido principalmente a la surgencia costera y advección horizontal de nutrientes.

    Full Text Available Frecuentemente en el registro arqueofaunístico de sitios arqueológicos ubicados en la vertiente occidental de la puna de Atacama, es posible diferenciar un conjunto de camélidos grandes y otro de menor tamaño. En general, el grupo de camélidos grandes ha recibido mayor atención, existiendo un escaso conocimiento del grupo de tamaño más pequeño. En este trabajo se explora el conjunto de camélidos pequeños a través de la utilización de métodos osteométricos. Por una parte, se consideran colecciones actuales de alpacas y vicuñas en las que se analizan las distintas variables que pudiesen estar incidiendo en la variabilidad de los conjuntos. Se otorga especial énfasis a la diferenciación entre falanges anteriores y posteriores, variación interespecífica y dimorfismo sexual. Por otra parte, se analizan las primeras falanges de los sitios Tulán-52 (Arcaico Tardío ca. 4500-3800 A.P. y Tulán-54 (Formativo Temprano ca. 3200-2300 A.P. con el fin de caracterizar la variabilidad que presentan los conjuntos a través del tiempo, mediante la comparación de los resultados del análisis de muestras actuales y arqueológicas. Ambos conjuntos arqueofaunísticos son muy similares a pesar de las diferencias temporales. Los especimenes analizados corresponderían a vicuñas, lo que denotaría la importancia de la caza de la vicuña a través del tiempo.Palabras clave:arqueofaunas,osteometria, alpacas, vicuñasAbstractFrequently, it is possible to differentiate among large and small size camelids when analysing registers from archaeological sites located at the occidental slope of Puna de Atacama. However, larger animals have received most of the attention having less knowledge about the group of small size camelids. In this paper and by using osteometric methods we study this small size later group. On one hand, we analyse different variables that may affect variability among modern alpacas and vicuñas collections. We focus our work on

    Full Text Available La comparación de las variaciones en el tiempo cronológico y en el espacio es uno de los aspectos menos estudiados en la ecología de las comunidades de parásitos. Por eso, en este estudio se compara la abundancia total, riqueza y composición de las infracomunidades de parásitos del róbalo Eleginops maclovinus (Cuvier & Valenciennes, 1830 (Pisces: Eleginopidae, entre muestras tomadas en Chile centro-sur en tres localidades geográficas (Talcahuano, Puerto Montt y Punta Arenas, y en dos momentos del tiempo en cada una de ellas. En el conjunto de las 126 infracomunidades examinadas se encontraron 18 taxa de parásitos. La abundancia total y la composición de las infracomunidades se modificaban con la ontogenia del hospedador. Sin embargo, se encontró que la variación entre años en una localidad es de similar magnitud a la que hay entre lugares geográficos, luego de corregir por el efecto de la ontogenia del hospedador. Estos resultados resaltan la necesidad de implementar diseños de muestreo más rigurosos al momento de usar a los parásitos como marcadores biológicos de las poblaciones de hospedadores. Se propone que futuros estudios en las fuentes de variación de las comunidades de parásitos mejoren la descripción de estas variaciones con diseños de muestreo con medidas replicadas en el tiempo y el espacio.Comparison of variations in both chronological time and space is one of the least studied subjects in the ecology of parasite communities. Thus, we compared the abundance, richness and composition of parasite infracommunities in the rock cod Eleginops maclovinus (Cuvier & Valenncienes, 1830 (Pisces: Eleginopidae, between three widely separated localities along south-central Chile (Talcahuano, Puerto Montt and Punta Arenas, which were sampled in two different years each.

    Full Text Available El análisis espacial y temporal de larvas de jurel Trachurus murphyien el mar peruano entre los años 1966 y 2010 confirma su presencia constante durante todo el periodo estudiado. En general, en este periodo la abundancia de larvas de jurel T. murphyimuestra una tendencia ligeramente ascendente destacándose cambios en la distribución espacial y una alta variabilidad interanual, con cortos periodos de alta abundancia promedio, intercalados con periodos más prolongados y de baja abundancia. El promedio anual estimado varió entre 3 y 79 larvas/ m2 . La distribución espacial presentó tres periodos importantes: uno con mayores densidades de larvas al sur de los 14°S, entre 1970 y 1979; cambió hacia el norte de esta latitud, entre 1980 y 1999; y otro de mayor densidad al sur de los 18°S, en el último periodo 2000 – 2010. Los centros de gravedad de la distribución de larvas presentaron tres periodos muy notorios: fueron más costeros hacia el sur de los 14°S, entre 1966 y1978; más oceánicos y al norte de los 14°S, entre 1979 y 1994; y con una posición intermedia entre 1995 – 2010. Se discute la relación entre la distribución de las larvas con las variables oceanográficas y la distribución de T. murphyiadultos y juveniles, además se destaca que el mar del Perú es un centro principal y permanente de actividad reproductiva de esta especie.

  18. La variabilidad de la lluvia al sur del paralelo 20º norte en el estado de Veracruz

    Full Text Available La finalidad primordial del estudio fué elegir las fórmulas mas adecuadas para determinar de una manera efectiva la variabilidad de la lluvia en nuestro país, a fin de preparar la programación primero, de la variabilidad de la lluvia en el estado de Veracruz y posteriormente en toda la República. Esta variación que se define como la diferencia con la media calculada en un período considerable de años de observación, es significativa debido a que tiene una relación directa, con las explotaciones agrícolas, con la vegetación y suelos, así como con la distribución de ios núcleos de población y la localización de zonas industriales y de almacenamiento de agua para diversos usos. En este trabajo se tomaron como base 19 estaciones meteorológicas distribuidas en la parte meridional del Estado de Veracruz, evitando que quedaran muy aglomeradas, ya que por tratarse de un trabajo experimental no era necesario emplearlas todas. Una vez reunidos los datos de precipitación anual de un período mayor de 12 años se procedió a calcular la variación interanual de la lluvia cuantificando y calculando la desviación que acusan los valores individuales respecto al promedio aritmético. Con el propósito de tener una idea de cómo la variabilidad afecta el desarrollo de la agricultura, se hizo un análisis de este tipo de actividad tomando como base datos estadísticos de producción de los siguientes cultivos: maíz, frijol, caña de azúcar y café, por tratarse de productos con un rendimiento y consumo muy elevados. Se concluyó que, en general, el rendimiento de los cultivos ofrece una tendencia a disminuir a medida que el coeficiente de variación aumenta; sin embargo hay algunas estaciones en que esto no sucede, lo cual pone de manifiesto que las características agrícolas de un lugar no sólo dependen de la variabilidad, sino de otros factores como son la topografía del terreno, el tipo de clima, las prácticas agrícolas empleadas

    Full Text Available There is still doubt as to the number of species of the freshwater Chilean ichthyofauna, 64 % of which have conservation problems. One of the groups is that of the silversides of the genus Basilichthys. Three morphological species of this genus have been described in Chile with disjoint distributions: Basilichthys semotilus, B. microlepidotus and B. australis; the latter two overlap in distribution only in the Aconcagua River and are not easily distinguishable by morphological and meristic characters. In order to evaluate the efficacy of identification of these species by molecular techniques, we analyzed the sequence of 9 % of the mitochondrial DNA (Control Region and COI of individuals from the Loa River (21°41' S to the Valdivia River (39°50' S, adding meristic features for B. microlepidotus and B. australis in order to study population variation to clarify the taxonomy of the native species of the genus. The phylogenetic analysis showed that the individuals of Basilichthys semotilus form an haplogroup separated from the other species of the genus; however, B. australis and B. microlepidotus form a monophyletic group that shares the most common haplotypes. An analysis of meristic information showed no statistically significant differences in the number of lateral line scales or number of rays in the fins between B. microlepidotus and B. australis. These results do not support the current classification for the latter two species; there appears to be one group in the extreme north of the country (Basilichthys semotilus and a second group in central Chile which should be called B. microlepidotus. This information will be useful to review the conservation status of the Chilean fauna.Si bien aún existen dudas sobre el número de especies descritas en el país, se reconoce que el 64 % de la ictiofauna dulceacuícola chilena se encuentra en alguna categoría de peligro de conservación.

En la provincia de Jujuy se encuentra a grandes alturas (entre los 2400 y los 3700 m s.m.. Existe una gran variabilidad morfológica, especialmente en cuanto a las dimensiones del fruto y la cantidad de semillas por fruto, ambas características importantes debido al uso de esta planta como forraje. Con el objeto de verificar si existe además variabilidad genética, se realizó un estudio electroforético de proteínas seminales de árboles procedentes de distintas localidades de la provincia de Jujuy. Los patrones polipeptídicos obtenidos por SDS-PAGE presentaron en total 26 bandas. Cada población se caracterizó por sus patrones de presencia-ausencia de bandas, habiéndose encontrado variabilidad intrapoblacional (polimorfismo en algunas de ellas, siendo otras genéticamente homogéneas. Los índices polimórficos en poblaciones de P. ferox son comparables a los obtenidos previamente en P. ruscifolia. La variabilidad genética interpoblacional hallada por medio del estudio electroforético de las proteínas seminales hace suponer la existencia de ecotipos

    2007-05-01

    El impacto de la variabilidad y cambio climáticos, afectan el potencial agrícola de la Región Sur de Tamaulipas. Además de los cambios estacionales, bajos rendimientos agrícolas, el manejo de los cultivos y las políticas locales de producción, existe la incertidumbre del mercado regional para los pequeños y grandes productores. La diversificación agrícola ha sido una alternativa para enfrentar las condiciones imperantes en esta región. Pero ésta ha provocado la fragmentación territorial, por lo que sólo algunos productores logran competir en un mercado nacional. Existe una preocupación generalizada por buscar soluciones que permitan que la población que es afectada por la inseguridad de la producción agrícola y económica, pueda adaptarse a las variaciones climáticas que afectan el proceso productivo. La seguridad alimentaría queda sujeta a la fluctuación de las importaciones para los sectores básicos y a las estrategias mercantiles de empresas trasnacionales. La percepción local sugiere un número creciente de eventos climatológicos extremos, constantes y severos en los últimos 20 años, con el aumento creciente de pérdidas económicas. El análisis se centra en la disponibilidad de agua, agregándose un aspecto de capital importancia como es la variabilidad interanual de la lluvia, que condiciona muy fuertemente el riesgo agrícola en el trópico seco, siendo ésta la que determina el momento de inicio de la estación favorable para el crecimiento y su duración. En este trabajo se han obtenido modelos de la distribución espacial de la precipitación y temperaturas, para el escenario base 1961-1990, el escenario actual 1971-2000, para algunos años El Niño y La Niña, así como para los escenarios de Cambio Climático HADLEY, ECHAM y GFDL, con escenarios A2 y B2, para las décadas de los 20s y 50s, para establecer el inicio y duración de la Estación de Crecimiento, utilizando Sistemas de Información Geográfica (ArcView).

Este artículo trata de distinguir entre los aspectos universales de la risa y los que son culturalmente variables. Define la risa como una emoción básica del ser humano, provocada por un estímulo cognitivo que depende de definiciones sociales de la situación, lo cual explica al menos en parte su aparente heterogeneidad. Otros aspectos que también pueden variar son las normas y costumbres relativas a la expresión de la risa y del humor, los géneros humorísticos, las instituciones del humor y las definiciones culturales de la risa misma.

    Full Text Available O conhecimento da Radiação Fotossinteticamente Ativa (RFA é importante para diferentes áreas relacionadas à fisiologia vegetal e ciências agrárias. Modelos de estimativa de RFA a partir da Radiação Global (Rg são extremamente úteis, visto que a Rg é convencionalmente medida nas estações meteorológicas. Assim, analisou-se a variabilidade sazonal da relação RFA/Rg em cinco áreas localizadas na bacia do rio Doce, Estado de Minas Gerais, considerando-se os períodos secos e chuvosos dos anos de 2001 a 2004. As relações RFA/Rg obtidas para os períodos secos e chuvosos, assim como para todos os dados, apresentaram concordância com as relações determinadas por diversos pesquisadores em diferentes áreas do mundo. Analisando-se os resultados, constatou-se que, de maneira geral,as relações RFA/Rg tendem a ser superiores durante os períodos chuvosos comparativamente aos secos. Por este estudo, pôde-se concluir que existe variação interanual desta relação, demonstrando assim a necessidade de se considerar esta variabilidade para estimaradequadamente a RFA a partir da Rg. The knowledge of the Photosynthetically Active Radiation (PAR is important to different areas of vegetal physiology and agricultural sciences. Estimation models of the PAR based on the Global Radiation (GR are extremely useful, since the GR is conventionally measured atthe meteorological stations. Thus, the seasonal variability of the relationship PAR/GR was analyzed in five areas located at the river Doce basin, Minas Gerais State, Brazil, considering the dry and wet periods of the years 2001 to 2004. The relationships PAR/GR obtained for the dry and wet periods, and also to all data, presented agreement with those ones determined by several researchers in different areas of the world. Results showed that the relationshipsPAR/GR generally tend to be greater during the wet periods when compared with the dry ones. By this work, it could be concluded that

    Full Text Available O rio São Francisco é um dos rios brasileiros mais extensos e sua importância também está no volume de água transportado por ele através da região semi-árida, na sua contribuição histórica e econômica para fi xação das populações ribeirinhas e na criação das cidades hoje plantadas ao longo do vale. O principal mecanismo produtor de chuvas sobre a bacia do rio São Francisco é a Zona de Convergência do Atlântico Sul (ZCAS. A intensidade e direção do vento são variáveis de grande interesse nos estudos de balanço de água. Portanto, o presente trabalho tem como objetivo estudar a climatologia do vento e sua variabilidade na bacia do rio São Francisco. Foram utilizados dados mensais de ventos, componentes zonal e meridional, oriundos da Reanálise do NCEP/NCAR no período de 1982-1994, em três faixas de longitude (40ºW, 42,5ºW e 45ºW entre as latitudes de 25ºS e 5ºS. Observou-se que nas longitudes de 42,5ºW e 45ºW, a posição média da ZCAS está em torno de 20º S. Também foi observado que a posição da ZCAS apresenta uma grande variabilidade interanual, pois, de dezembro/1982 a fevereiro/1983 a ZCAS posicionou-se ao sul de 25ºS, enquanto no período de dezembro/1988 a fevereiro/1989 estava em torno de 15ºS. O posicionamento médio meridional da ZCAS em torno de 20º é de fundamental importância para produção de chuva sobre a bacia do rio São Francisco.

    Full Text Available La variabilidad espacial y temporal del ciclo anual de la clorofila-α en el archipiélago de Juan Fernández se analiza usando ocho anos de datos satelitales de clorofila-α, viento, corrientes y nivel del mar. Este archipiélago está conformado por tres islas: Robinson Crusoe-Santa Clara (RC-SC y Alejandro Selkirk (AS. Las islas RC-SC se encuentran en una región de alta energía cinética y mayores concentraciones de clorofila-α definida como Zona de Transición Costera, en cambio la isla AS se encuentra en una región de baja energía cinética y menores concentraciones de clorofila-α denominada Zona Oceánica. RC-SC posee un incremento de las concentraciones de clorofila-a en el lado suroeste, mientras que AS posee sus mayores concentraciones en el lado oeste, indicando la presencia de procesos forzantes diferentes. En ambas islas el ciclo anual de la clorofila es significativo y comienza a incrementar en abril, alcanzando valores relativamente altos entre junio y noviembre, disminuyendo hacia diciembre, hasta alcanzar un mínimo hacia fines de marzo. Este ciclo anual aparece desacoplado con el viento y acoplado con la energía cinética. Incrementos invernales de clorofila-a aparecen vinculados con remolinos de mesoescala provenientes de la zona continental, mientras que incrementos primaverales se podrían asociar a procesos locales vinculados al "efecto masa de isla". En ambas islas existen incrementos significativos de la clorofila-a en la banda anual y cuasi-bianual, pero sólo en AS se encontró una fluctuación significativa en la banda interanual vinculada con el Nino y la Oscilación del Sur.

    Current projections indicate that Chile will host approximately 70% of the astronomical collecting area on Earth by 2030, augmenting the enormous area of ALMA with that of three next-generation optical telescopes: LSST, GMTO, and E-ELT. These cutting-edge facilities represent billions of dollars of investment in the astronomical facilities hosted in Chile. The Chilean government, Chilean astronomical community, and the international observatories in Chile have recognized that these investments are threatened by light pollution, and have formed a strong collaboration to work at managing the threats. We will provide an update on the work being done in Chile, ranging from training municipalities about new lighting regulations to exploring international recognition of the dark sky sites of Northern Chile.

    The author describes a joint program to use renewables for rural electrification projects in Chile. The initial focus was in a limited part of the country, involving wind mapping, pilot project planning, training, and development of methodologies for comparative evaluations of resources. To this point three wind hybrid systems have been installed in one region, as a part of the regional private utility, and three additional projects are being designed. Additional resource assessment and training is ongoing. The author points out the difficulties in working with utilities, the importance of signed documentation, and the need to look at these programs as long term because of the time involved in introducing such new technologies.

    Mental disorders are among the most prevalent of chronic disorders, and a high prevalence of these disorders has been consistently found in jails and prisons. This study was a retrospective case series that described the population of adults charged with a criminal offense who were court ordered to undergo a psychiatric assessment within the Medical Legal Service in Santiago, Chile from 2005 to 2006. Characteristics were explored in order to better understand this population in light of the recent reforms in the judicial and health systems of Chile. Ninety percent of sampled individuals were male, primarily between the ages of 18-39 years. Seventy percent of the evaluations came from the pre-reformed judicial system and 30% were from the reformed system. Approximately 63% of evaluated offenders were considered to have a psychiatric pathology, the most common being the personality disorders. Of the evaluated offenders, approximately 84% were considered by a psychiatrist to be criminally responsible for their crime, 7% were regarded as having diminished criminal responsibility, 4% were considered to be not criminally responsible for their crime, and 4% were cases where criminal responsibility was not applicable. Profession status, municipality of residence, type of residence, ICD-10 diagnosis, treatment recommendation, and criminal responsibility were found to be significantly different between male and female evaluated offenders. Results from this investigation will contribute to knowledge about forensic psychiatry and mental health in Latin America, and will hopefully pave the way for more research and international comparisons.

    Full Text Available The development of research in robotics in a developing country is a challenging task. Factors such as low research funds, low trust from local companies and the government, and a small number of qualified researchers hinder the development of strong, local research groups. In this article, and as a case of study, we present our research group in robotics at the Advanced Mining Technology Center of the Universidad de Chile, and the way in which we have addressed these challenges. In 2008, we decided to focus our research efforts in mining, which is the main industry in Chile. We observed that this industry has needs in terms of safety, productivity, operational continuity, and environmental care. All these needs could be addressed with robotics and automation technology. In a first stage, we concentrate ourselves in building capabilities in field robotics, starting with the automation of a commercial vehicle. An important outcome of this project was the earn of the local mining industry confidence. Then, in a second stage started in 2012, we began working with the local mining industry in technological projects. In this article, we describe three of the technological projects that we have developed with industry support: (i an autonomous vehicle for mining environments without global positioning system coverage; (ii the inspection of the irrigation flow in heap leach piles using unmanned aerial vehicles and thermal cameras; and (iii an enhanced vision system for vehicle teleoperation in adverse climatic conditions.

    ESO, the European Southern Observatory, in reply to questions raised by the international media, as well as an ongoing debate about the so-called "Paranal case" in Chilean newspapers, would like to make a number of related observations concerning its status and continued operation in that country [1]. THE ESO OBSERVATORY SITES IN CHILE The European Southern Observatory, an international organisation established and supported by eight European countries, has been operating more than 30 years in the Republic of Chile. Here ESO maintains one of the world's prime astronomical observatories on the La Silla mountain in the southern part of the Atacama desert. This location is in the Fourth Chilean Region, some 600 km north of Santiago de Chile. In order to protect the La Silla site against dust and light pollution from possible future mining industries, roads and settlements, ESO early acquired the territory around this site. It totals about 825 sq. km and has effectively contributed to the preservation of its continued, excellent "astronomical" quality. Each year, more than 500 astronomers from European countries, Chile and elsewhere profit from this when they come to La Silla to observe with one or more of the 15 telescopes now located there. In 1987, the ESO Council [2] decided to embark upon one of the most prestigious and technologically advanced projects ever conceived in astronomy, the Very Large Telescope (VLT). It will consist of four interconnected 8.2-metre telescopes and will become the largest optical telescope in the world when it is ready. It is safe to predict that many exciting discoveries will be made with this instrument, and it will undoubtedly play a very important role in our exploration of the distant universe and its many mysteries during the coming decades. THE VLT AND PARANAL In order to find the best site for the VLT, ESO performed a thorough investigation of many possible mountain tops, both near La Silla and in Northern Chile. They showed

    In 1566 Alonso de Villadiego was nominated by the Chilean Cabildo as "Adviser and Examiner in Surgery". By means of this edict, the Spanish Crown paralleled its classical health organization, inspired in rules coming from XIIIth century. The Hospital del Socorro was the focal point of these activities. It turned to be prosperous under the administration of "San Juan de Dios" monks (1617), who rebaptized the Hospital with their name. During the administration of the "Universidad de San Felipe" (1738-1839), the Protomedicato followed the standards imposed by the Cahir of Prima Medicina. Domingo Nevin, Frenchman, and José Antonio Ríos, Chilean, were the first and the last doctors in charge of this task. Ríos conducted the antivariolic campaign, supervised the "Midwifery Law" and controlled the medical and paramedical practice. Afterwards, the Institution plunged into a profound crisis to reflourish in 1833 when it was incorporated within the structure of the School of Medicine. Blest, Cox, Bustillos and Moran were the architects of its splendour. With the foundation of the Universidad de Chile in 1842, its Faculty of Medicine took over the Protomedicato functions. The Institution came to an end in 1892.

    Servicio Paz y Justicia (SERPAJ) is a nongovernmental organization (NGO) established in Chile in 1977. It supports fundamental human dignity and rights by fighting discrimination and exclusion based upon individual differences. SERPAJ promotes training, organization, and the political participation of community members as part of the democratic process, working mainly with the at risk women, street children, and youth of Santiago's working-class neighborhoods. Groups participate in workshops and training courses on human rights and development, civic education, and methods of non-violent community action. In 1987, SERPAJ-Sur Oriente began to include the topic of sexuality and AIDS/STDs in courses training working-class women as community human rights agents. The NGO is therefore one of the first mainstream Chilean human rights organizations to incorporate HIV/AIDS issues. A basic facts brochure was developed, followed by a pilot education project developed in one neighborhood which was then systematically replicated in other neighborhoods. The comments of some people who have participated in SERPAJ workshops are presented.

Em geral, os resultados indicam que do ponto de vista espacial, a precipitação mensal varia consideravelmente, pois as três cidades estudadas localizam-se em diferentes continentes da faixa tropical. Isto ocorre principalmente, durante os meses de Janeiro a Maio, período de maior atuação da ZCIT no hemisfério sul. As variações atmosféricas observadas, a partir dos escalogramas de fase, - de ondeleta indicam que as escalas interdecadal, anual, interanual e intrassazonal são moduladoras da precipitação. Tais escalas podem ser representadas pelos mecanismos oceano-atmosfera dos fenômenos El Niño Oscilação Sul e da oscilação intrassazonal de Madden e Julian. A contribuição destes fenômenos na distribuição da chuva nessas regiões é evidente durante o período estudado, sendo que Nairóbi, apesar de estar localizada em latitude semelhante à de Belém, apresenta pouca evidência do ciclo anual e forte na escala interdecadal. No caso de Belém e de Jakarta as oscilações de múltiescala de precipitação concentram-se nas escalas dos mecanismos moduladores da chuva associados com o ciclo anual e intrassazonal, durante todo o período.This study aims to present an atmospheric analysis of spatial and temporal variability of the Intertropical Convergence Zone (ITCZ in Belem, Jakarta and Nairobi, which are located on the continents of South America, Asia and Africa, respectively.

  15. Chile Energy Policy Review 2009

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2009-10-22

    Since 1990, Chile has been the fastest growing economy in Latin America thanks to sound economic management and integration into the global economy. Chile can also be proud of its energy policy achievements. The pioneering privatisation and liberalisation of its electricity sector in the 1980s was the foundation for a competitive energy sector, which has sustained the rapid growth of the Chilean economy over the past two decades. Nonetheless, Chile faces the continuing challenge of finding additional energy supplies to fuel economic growth. Chile has limited fossil energy resources and depends on imports to meet three-quarters of its energy needs. The country's electricity sector has faced three periods of significant stress over the past decade. The last episode took place in 2007/2008, when the loss of natural gas imports from Argentina was further exacerbated by a drought in the central system, where hydropower normally accounts for over half of electricity generation. Drawing on the experience of IEA member countries, the Review assesses Chile's major energy challenges and provides recommendations. Six main themes emerge: the successful liberalisation of the power sector in the 1980s; the essential role played by the state in ensuring energy security; the re-formulation of Chile's long-term energy policy; the proposed reorganisation of the institutional framework; greater independence for the system operators; and the need for a clear framework of regulation so that long-term investment decisions integrate social and environmental costs. This publication is essential reading for all who are interested in Chilean energy issues and in learning about the important role sound energy policy can play in developing a nation's economic and social welfare.

  16. Wildfires in Chile: A review

    Science.gov (United States)

    Úbeda, Xavier; Sarricolea, Pablo

    2016-11-01

    This paper reviews the literature examining the wildfire phenomenon in Chile. Since ancient times, Chile's wildfires have shaped the country's landscape, but today, as in many other parts of the world, the fire regime - pattern, frequency and intensity - has grown at an alarming rate. In 2014, > 8000 fires were responsible for burning c. 130,000 ha, making it the worst year in Chile's recent history. The reasons for this increase appear to be the increment in the area planted with flammable species; the rejection of these landscape modifications on the part of local communities that target these plantations in arson attacks; and, the adoption of intensive forest management practices resulting in the accumulation of a high fuel load. These trends have left many native species in a precarious situation and forest plantation companies under considerable financial pressure. An additional problem is posed by fires at the wildland urban interface (WUI), threatening those inhabitants that live in Chile's most heavily populated cities. The prevalence of natural fires in Chile; the relationship between certain plant species and fire in terms of seed germination strategies and plant adaptation; the relationship between fire and invasive species; and, the need for fire prevention systems and territorial plans that include fire risk assessments are some of the key aspects discussed in this article. Several of the questions raised will require further research, including just how fire-dependent the ecosystems in Chile are, how the forest at the WUI can be better managed to prevent human and material damage, and how best to address the social controversy that pits the Mapuche population against the timber companies.

    1998-07-01

    Full Text Available En estudios de educación, es de gran interés tratar de determinar la importancia que tienen las características propias de los colegios sobre el rendimiento que obtienen sus estudiantes. En otras palabras, los investigadores quieren saber qué porcentaje de la variabilidad del rendimiento es explicado por el “efecto colegio”. Desafortunadamente, en la mayoría de los estudios realizados hasta ahora, esta pregunta ha quedado sin respuesta debido a que las técnicas usadas, como la regresión lineal estándar, no permiten descomponer la variabilidad del rendimiento entre la variabilidad explicada por las características propias de los estudiantes y la explicada por las características de los colegios. Dichas técnicas fallan al no reconocer que en estos casos los datos son generados por estructuras jerárquicas, es decir los datos son observados en diferentes niveles: generalmente se tiene variables que describen los individuos, y los individuos están agrupados en unidades más grandes de las cuáles también se tienen variables que las describen. Este trabajo ilustra como el uso de los modelos jerárquicos lineales (Mason, Wong y Entwistle, 1983; Bryck y Raundenbush, 1992 sobre la Encuesta Saber 93, permite concluir que aproximadamente el 29% de la varianza del rendimiento en matemáticas de los estudiantes de tercero de primaria es explicada por el efecto colegio.

Nela mapas de produtividade indicam a localização de áreas críticas, ajudando a fazer intervenções localizadas, a fim de aumentar a produtividade e consequentemente a rentabilidade. Objetivou-se avaliar a variabilidade espacial da produtividade, perdas quantitativas na colheita mecanizada e a lucratividade em área de produção de soja. Realizou-se um levantamento de dados georreferenciados em uma área de 20,90 ha. Foram utilizadas técnicas geoestatísticas para a determinação da variabilidade espacial. A dependência espacial foi moderada para todos os parâmetros estudados, observando-se regiões com maior ou menor variabilidade espacial na produtividade, nas perdas quantitativas de grãos e na lucratividade. A produtividade média foi de 3.748,63 kg.ha-1 e 67,65 % da área total apresentou patamares de produtividade de 3.254,05 a 3.609,91 kg.ha-1 e de 3.609,91 a 3.965,91 kg.ha-1. As perdas totais de grãos encontrados por ocasião da colheita foram baixas (49,59 kg.ha-1. A lucratividade média foi 1.252,54 $.ha-1, com duas regiões representativas de lucro de 1.187,20 a 1.354,78 $.ha-1 e de 1.019,62 a 1.187,20 $.ha-1, correspondente a 67,65 % da área total. Pode-se dizer que a semelhança na variabilidade espacial dos mapas de produtividade e lucratividade ocorre por este último ter sido confeccionado a partir de dados de produtividade, o que permitiria ao produtor investigar os motivos das baixas produtividades, sugerindo eventualmente um estudo da fertilidade do solo, no intuito de encontrar e corrigir o problema que levou às baixas produtividades, a fim de melhorar a relação custo/benefício, tendo como resultado um maior lucro.

    2009-01-01

    Within the last decade natural gas gained considerable importance in Chile. The contribution of natural gas within the energy system will increase in the future by predicted 3.6% annually until the year 2015. Due to limited resources within its own country, the energy system of Chile depends on natural gas imports preferential from Argentina. Therefore, the aim of several stakeholders from policy and industry is to reduce the share of imported primary energy within the overall energy system. In order to reach this goal, the use of domestic resources and particularly the utilisation of biomass as one of the most important renewable sources of energy in Chile could play an important role. Against this background, the goal of this paper is the analysis of the technical potentials of biomethane as a substitute for natural gas. For the production of biomethane the anaerobic or bio-chemical (i.e. Biogas) as well as the thermo-chemical conversion pathways (i.e. Bio-SNG) are considered. The results of this analysis show that biomass converted to biomethane is a promising energy provision option for Chile and it contributes to the reduction of greenhouse gas emissions

O objetivo desta pesquisa foi analisar as causas da variabilidade do tempo de execução dos processos em diferentes sistemas construtivos, classificando-as em níveis de risco. A metodologia consistiu em um estudo de casos múltiplos em diferentes sistemas construtivos, sendo aplicado com diversos trabalhadores de obras um questionário com 31 causas de variabilidade divididas em oito categorias. Visou-se levantar as variáveis frequência e intensidade de atraso. Foram observadas obras de concreto armado (convencional, alvenaria estrutural e paredes de concreto moldadas no local. Para a análise dos dados foi criado um fator de atraso e aplicada uma metodologia de classificação das causas em níveis de risco através da análise de clusters. Como resultados foram apontadas as principais causas de variabilidade para cada um dos sistemas, sendo algumas semelhantes: retrabalho, baixa qualidade do trabalho e socialização. Análises estatísticas apontaram diferenças entre os sistemas: aqueles mais industrializados tiveram maior quantidade de causas classificadas em níveis de alto risco, porém o impacto da variabilidade no processo foi menor. Há deficiências por parte dos gestores para lidar com os impactos da variabilidade nos processos.

    Full Text Available La longitud de rugosidad es un parámetro de escala característico de la capa de superficie, utilizado en estudios micrometeorológicos, de contaminación urbana, de potencial eólico o en los modelos dinámicos de pronóstico del tiempo y el clima. Experimentalmente este parámetro se determina a partir de datos observacionales del perfil de viento bajo condiciones neutrales de estabilidad atmosférica. Sin embargo, existen evidencias de una dependencia del mismo con los cambios en la estabilidad. Utilizando datos observados sobre una superficie con cobertura vegetal y bajo las hipótesis de la teoría de la semejanza de Monin-Obukhov, se estudió la variabilidad del parámetro de rugosidad con la estabilidad atmosférica. Se obtuvieron expresiones empíricas que permitieron estimar esa longitud en función de un parámetro de estabilidad. Se encontraron variaciones en su magnitud de hasta dos órdenes bajo condiciones estables, mientras que en condiciones inestables su variabilidad fue pequeña. Por otra parte, se estudió el impacto que producen las parametrizaciones obtenidas al aplicarlas en un preprocesador meteorológico para un modelo de difusión de contaminantes. Los resultados obtenidos tendrían un impacto directo en el campo de velocidades cercano a superficie

    A January 6, 2002 ASTER nighttime thermal infrared image of Chiliques volcano in Chile shows a hot spot in the summit crater and several others along the upper flanks of the edifice, indicating new volcanic activity. Examination of an earlier nighttime thermal infrared image from May 24,2000 showed no thermal anomaly. Chiliques volcano was previously thought to be dormant. Rising to an elevation of 5778 m, Chiliques is a simple stratovolcano with a 500-m-diameter circular summit crater. This mountain is one of the most important high altitude ceremonial centers of the Incas. It is rarely visited due to its difficult accessibility. Climbing to the summit along Inca trails, numerous ruins are encountered; at the summit there are a series of constructions used for rituals. There is a beautiful lagoon in the crater that is almost always frozen.The daytime image was acquired on November 19, 2000 and was created by displaying ASTER bands 1,2 and 3 in blue, green and red. The nighttime image was acquired January 6, 2002, and is a color-coded display of a single thermal infrared band. The hottest areas are white, and colder areas are darker shades of red. Both images cover an area of 7.5 x 7.5 km, and are centered at 23.6 degrees south latitude, 67.6 degrees west longitude.Both images cover an area of 7.5 x 7.5 km, and are centered at 23.6 degrees south latitude, 67.6 degrees west longitude.These images were acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. With its 14spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER will image Earth for the next 6 years to map and monitor the changing surface of our planet.ASTER is one of five Earth-observing instruments launched December 18,1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U

    Chile bliver ofte præsenteret som et paradigme for resten af det latinamerikanske kontinent: Et land med høj økonomisk vækst og politisk stabilitet. Landet har endda haft to socialistiske præsidenter siden 2000, den sidste den første kvindelige præsident. Succeshistorien har en bagside: De...... socialistiske regeringer har accepteret et begrænset demokrati og videreført en nyliberal økonomisk politik, der har bragt dem på konfrontationskurs med massebevægelserne og isoleret Chile fra de andre lande i regionen, der søger integration og gensidig støøte.

    Full Text Available Crocodylus moreletii representa un emblema para los ecosistemas tropicales de México pero actualmente está amenazada por extinción. Sorprendentemente, hay una falta de información de su constitución genética, que debe ser evaluada para un manejo apropiado ex situ y para toma de decisiones en la liberación de cocodrilos a su hábitat natural. El objetivo del estudio fue caracterizar y comparar la variabilidad genética de cuatro grupos poblacionales de C. moreletii (dos silvestres y dos nacidas ex situ. Mediante PCR se amplificaron siete loci de microsatélites polimórficos, sin embargo se encontró déficit de heterocigotos en las poblaciones (promedio H O=0.02 mermado por la presencia de alelos nulos. El AMOVA indicó que la mayor proporción de variabilidad genética se encuentra dentro de las poblaciones y una limitada diferenciación genética entre poblaciones (promedio F ST =0.03, probablemente debida al alto índice de endogamia (promedio F IS=0.97. Al comparar la variabilidad genética inter e intra especies de cocodrilianos, encontramos que en C. moreletii está muy por debajo de los reportados. Se concluye que la limitada variabilidad genética de las poblaciones nacidas ex situ probablemente se debe al efecto fundador derivado de la estructura social de sus progenitores, y de las poblaciones silvestres, por el efecto cuello de botella, inferido por el limitado tamaño efectivo de población que presentó históricamente en su distribución natural.

  7. Letter from Chile: Re-establishing health care in Chile

    Science.gov (United States)

    Jiménez, Jorge

    1993-01-01

    Chile's long term social policy has produced very impressive outcomes in general health indicators, with a national health service established as early as 1952. During the years of the Pinochet dictatorship (1973-89) public health institutions were greatly affected, with sharp diminution in financing which affected investment and salaries. The democratic government initiated in 1990 faced a difficult situation, with underpaid staff and decrepit hospitals. The ministry took immediate action to improve salaries and start an ambitious health sector reform including investment in infrastructure, technology, and modern management. Decentralisation and autonomy, changes in payment for service mechanisms, and a public-private mix are the main objectives of this reform, keeping the public role as predominant in the proposed structure. This process has been affected by union unrest and public opinion dissatisfaction, which tend to present obstacles to progress in this complicated issue. Imagesp729-ap730-a

    F. M. Almeida Filho

    Full Text Available Esta pesquisa tem como objetivo estudar a variabilidade das propriedades mecânicas (resistência à compressão, módulo de elasticidade longitudinal e resistência à tração e da resistência de aderência do concreto auto-adensável (CAA, com resistência à compressão do concreto de 50 MPa aos 28 dias, variando o tamanho máximo do agregado graúdo e sua fluidez. Os ensaios foram realizados em corposde- prova de 15 x 30 cm e em vigas padronizadas de acordo com o Rilem-Ceb-Fib (1973. De acordo com os resultados obtidos, pode-se concluir que a variabilidade do concreto auto-adensável é pequena para o módulo de elasticidade e para a resistência à compressão e grande para a resistência à tração por causa do modo de ruptura do modelo. Com relação à resistência de aderência, a variabilidade foi pequena mostrando que o concreto auto-adensável é material confiável com grande potencial de utilização no mercado da construção civil.

    Full Text Available O presente trabalho teve por objetivo avaliar a variabilidade espacial da sodicidade do solo em rampas cultivadas com Brachiaria humidicula e Zoysia japonica para tratamento de esgoto sanitário. Na estação de tratamento de esgoto do município de Januária/MG foram coletadas amostras de solo em duas rampas de tratamento de esgoto, uma cultivada com Brachiaria humidicula (RCBH e outra cultivada com Zoysia japonica (RCZJ. Foram realizadas análises de químicas do solo e com isso determinou-se a Razão de Adsorção de Sódio (RAS e a Porcentagem de Sódio Trocável (PST. Os dados foram submetidos à geoestatística. As maiores variabilidades foram observadas para a RAS e PST da RCBH, sendo classificadas como elevadas. Na análise da dependência espacial foi possivel observar que as variáveis estudadas apresentam forte correlação espacial, com excessão da RAS obtida da RCZJ que é considerada de fraca. Apesar da alta variabilidade espacial, a amplitude dos valores de RAS e PST encontrados nas rampas são pequenas não apresentando grandes riscos a salinização do solo a curto prazo.

Folhas de 18 acessos de araticum foram coletadas e utilizadas para a extração das amostras de DNA genômico, as quais foram amplificadas para obtenção de marcadores moleculares RAPD e microssatélites. Na análise morfológica, foram avaliadas 23 características dos acessos de araticum. As dissimilaridades genéticas entre os 18 genótipos de araticum evidenciaram a variabilidade genética dos acessos e as análises de agrupamento levaram à formação de três grupos de similaridade. Verificaram-se coeficientes de dissimilaridades genéticas baixos entre os materiais oriundos da Embrapa Cerrados e altos entre os outros materiais. Esses acessos são importantes fontes de variabilidade para o enriquecimento da atual coleção de trabalho da Embrapa Cerrados e para futuros estudos de caracterização morfológica e agronômica.

    The leading health problems of children and adolescents in Chile is reviewed. The Chilean educational system and how the system addresses its principal health problems are described. A school health program is described as well as other educational programs designed and developed by nongovernmental institutions which have a smaller coverage. Current research studies regarding growth and development, child morbidity, nutritional level, and mental health studies are reviewed. In addition, principal challenges that include developing more efficient ways of referring children, enriching the curriculum and teacher training, assigning school hours for health teachers, and enlarging coverage of the health care evaluation programs are outlined. Of special importance is developing prevention programs for parents and children using school and community leaders to prevent health problems in areas such as human sexuality education, decision-making, social abilities, and alcohol and drug abuse. Main efforts should be directed toward low-income families and children to improve life conditions.

    1997-12-01

    This paper describes a village application in Chile. The objective was to demonstrate the technical, economic and institutional viability of renewable energy for rural electrification, as well as to allow local partners to gain experience with hybrid/renewable technology, resource assessment, system siting and operation. A micro-grid system is viewed as a small village system, up to 1200 kWh/day load with a 50 kW peak load. It can consist of components of wind, photovoltaic, batteries, and conventional generators. It is usually associated with a single generator source, and uses batteries to cover light day time loads.

    The planned construction of two hydroelectric power plants at Peuchen and Mampil, will help to meet Chile's growing electricity demand. Securing finance for the project has been straight forward thanks to the optimal hydrological conditions, rivers with a very strong flow providing a large head of water over short distance. Hydropower plays a central role in Chile's generating capacity providing 70% of total energy consumption. Thus, the future of these projects will be highly successful, it is argued. (UK)

El presente trabajo incluye una breve compilación acerca de la historia de la familia y de las primeras expediciones realizadas en Chile. También se realizan comparaciones de la diversidad de carábidos chilenos con respecto a otros países y el Neotrópico. Para Chile, se conocen 21 tribus, con 95 géneros y 365 especies, que representan el 38,8, 28,8 y 7,9 % de la fauna del Neotrópico, respectivamente. Chile posee un bajo número de tribus comparado con otros países, sin embargo, constituye un área importante por la presencia de seis tribus relictuales, principalmente pangeicas o gondwánicas. Chile posee 18 géneros endémicos (18,5 % de su fauna de Carabidae, 28 cuya distribución está restringida a Chile y Argentina y seis restringidos a Chile, Argentina y Uruguay. La cantidad de especies presentes en Chile es inferior a la que poseen otros países de América del Sur, pero la cantidad de especies endémicas es muy alta (204 y representa el 55,8 % de su fauna de carábidos. El alto grado de endemismo que posee Chile con respecto a otros países de América del Sur puede deberse a su condición de aislamiento, siendo las barreras más importantes la región desértica del norte y la cordillera de Los Andes. Este hecho también se vislumbra por la ausencia de importantes tribus neotropicales como Galeritini, Scaritini y Brachinini. También se incluyen en este trabajo claves para la identificación de todas las tribus y géneros presentes en Chile, como así también una breve descripción acerca de la diversidad y ambientes en los que se encuentra cada géneroThe family Carabidae is the fourth largest Coleoptera family in Chile.

    O'Ryan, Miguel; Valenzuela, María Teresa

    2008-11-01

    Molecular, clinical and epidemiological studies have established beyond doubt that human papiloma viruses (HPV) cause cervical cancer. The virus is also associated with genital warts and other less common cancers in oropharynx, vulva, vagina and penis. Worldwide, VPH genotypes 16 and 18 are the most common high risk genotypes, detected in near 70% of women with cervical cancer. The discovery of a cause-effect relationship between several carcinogenic microorganisms and cancer open avenues for new diagnostic, treatment and prevention strategies. In this issue of Revista Médica de Chile, two papers on HPV are presented. Guzman and colleagues demonstrate that HPV can be detected in 66% to 77% of healthy male adolescents bypolymerase chain reaction and that positivity depends on the site of the penis that is sampled. These results support the role of male to female transmission of high risk HPVs in Chile and should lead to even more active educational campaigns. The second paper provides recommendations for HPV vaccine use in Chile, generated by the Immunization Advisory Committee of the Chilean Infectious Disease Society. To issue these recommendations, the Committee analyzes the epidemiological information available on HPV infection and cervical cancer in Chile, vaccine safety and effectiveness data, and describes cost-effectiveness studies. Taking into account that universal vaccination is controversial, the Committee favors vaccine use in Chile and it's incorporation into a national program. However, there is an indication that the country requires the implementation of an integrated surveillance approach including cross matching of data obtained from HPV genotype surveillance, monitoring of vaccination coverage, and surveillance of cervical cancer. The final decision of universal vaccine use in Chile should be based on a through analysis of information.ev Mid Chile

    While some countries have unbundled distribution and retailing, skeptics argue that the physical attributes of electricity make retailers redundant. Instead, it is claimed that passive pass through of wholesale prices plus regulated charges for transmission and distribution suffice for customers to benefit from competitive generation markets. We review the Chilean experience with regulated retailing and pass through of wholesale prices. We argue that when energy wholesale prices are volatile and prices are stabilized, distortions emerge. Regulated retailers gain little by mitigating or correcting them. On the contrary, sometimes price distortions increase their profits. We estimate the cost of three distortions that neither regulated retailers nor the regulator have shown any interest in correcting. - Highlights: > We review Chile's experience with regulated electricity retailing. > Distortions emerge when energy wholesale prices are volatile and prices stabilized. > Regulated retailers gain little by mitigating or correcting distortions. > Sometimes price distortions increase retailers' profits. > We estimate the cost of three distortions, which retailers have not corrected.

    1989-01-01

    The Chilean Red Cross Society and the family planning association--APROFA, International Planned Parenthood Federation's affiliate, are joining forces to help prevent the spread of the acquired immunodeficiency syndrome (AIDS) and human immunodeficiency virus (HIV) infection. APROFA established a working group to study the knowledge, attitudes, and sexual behavior of students at the National Training Institute, INACAP. 7000 students were sampled in 11 Chilean cities. The study found that 36% of the females, and 77% of males were sexually active before the age of 20. Nearly 1/2 of the women and 1/5 of the men did not know that condoms could protect them against sexually transmitted diseases (STDs) and pregnancy. APROFA designed a program to increase students knowledge of AIDS, reduce promiscuity and increase knowledge of and use of condoms. In October, 1988 an educational package distributed, consisting of a training manual, slides, educational booklets, a poster, and a video of 3 films. It has proved so successful that APROFA has adapted it for community groups, educational institutions, and its youth program. APROFA/Red Cross nurses and Red Cross volunteers have participated in workshops and training with the package. The Red Cross has organized AIDS-related activities in Chile since 1986, including education campaigns, information for blood donors, and a telephone hotline to provide AIDS counseling. Goals are to target more poor areas and groups outside of society's mainstream in the next year for sex education and information on STDs.

    Full Text Available Este artículo presenta una metodología para la gestión de la demanda en ambientes multiproducto para diferentes eslabones de la cadena de suministro y con alta variabilidad en la demanda. La metodología propuesta consiste en dos fases: la primera busca una clasificación de los productos de acuerdo con dos criterios, uno de movimiento para representar la rotación de inventarios, y el segundo de importancia respecto a las variables costo, volumen y peso; el resultado de esta fase es un conjunto de categorías para clasificar los productos e identificar aquellos más importantes y aquellos que se deben descontinuar. La segunda fase consiste en realizar un pronóstico agregado de acuerdo con la variabilidad que se presenta en cada una de las categorías identificadas, se emplea el coeficiente de variación como medida de variabilidad y suavización exponencial doble y promedios móviles dobles como técnica de pronóstico, aunque la metodología es flexible y se pueden emplear otros métodos de series de tiempo. La metodología se implementó en una empresa líder en Colombia de productos polivinilos logrando una mejora del 10 % en la desviación absoluta promedio, aproximadamente. Por otro lado, se logró una reducción significativa en el inventario promedio de todo el sistema. Finalmente, este trabajo es una fase inicial para una clasificación dinámica de los productos para gestionar de forma integral los inventarios en una cadena de múltiples eslabones.

    Full Text Available Os investimentos no campo vêm sendo ampliados ao longo das últimas décadas, sobretudo pela justificativa de se minimizar as repercussões, ditas “naturais”, no território agrícola ocupado. O objetivo deste artigo é analisar a variabilidade das chuvas na vertente paranaense da bacia do rio Paranapanema em período de safra de soja (outubro – abril. Para tanto, foram aplicadas duas técnicas estatísticas: Mann-Kendall e Percentil, com o intuito de estudar a tendência e a variabilidade dos totais anuais de chuva da série histórica entre os anos 1999-2000 a 2009-2010. Para isso utilizou-se dados de precipitação de 89 postos pluviométricos administrados pelo Instituto das Águas do Paraná. Ademais, definiram-se períodos extremamente secos, secos, habituais, chuvosos e extremamente chuvosos, representados em um painel tempo-espacial. Quanto ao teste de Mann-Kendall: 13 postos pluviométricos apresentaram tendência positiva de aumento das chuvas. No que se refere aos resultados mais expressivos relacionados à variabilidade da chuva anual acumulada, concluiu-se que o ano agrícola de 1999–2000 foi definido como padrão seco, em contraposição ao ano agrícola chuvoso de 2009–2010. Os valores de produtividade de soja utilizados para medir o impacto desses períodos extremos também evidenciam variações em resposta aos registros pluviométricos de cada ano.

    A Facility for immobilizing and conditioning of radioactive wastes generated in Chile, has recently started in operation. It is a Radioactive Wastes Treatment Plant, RWTP, whose owner is Comision Chilena de Energia Nuclear, CCHEN. A Storgement Building of Conditioned Wastes accomplishes the facility for medium and low level activity wastes. The Project has been carried with participation of chilean professionals at CCHEN and Technical Assistance of International Atomic Energy Agency, IAEA. Processes developed are volume reduction by compaction; immobilization by cementation and conditioning. Equipment has been selected to process radioactive wastes into a 200 liters drum, in which wastes are definitively conditioned, avoiding exposition and contamination risks. The Plant has capacity to treat low and medium activity radioactive wastes produced in Chile due to Reactor Experimental No. 1 operation, and annex Laboratories in Nuclear Research Centers, as also those produced by users of nuclear techniques in Industries, Hospitals, Research Centers and Universities, in the whole country. With the infrastructure developed in Chile, a centralization of Radioactive Wastes Management activities is achieved. A data base system helps to control and register radioactive wastes arising in Chile. Generation of radioactive wastes in Chile, has found solution for the present production and that of near future

    2011-10-01

    Disability is a worldwide public health priority. A shift from a biomedical perspective of dysfunction to a broader social understanding of disability has been proposed. Among many different social factors described in the past, socioeconomic position remains as a key multidimensional determinant of health. The study goal was to analyze the relationship between disability and different domains of socioeconomic position in Chile. Cross-sectional analysis of an anonymized population-based survey conducted in Chile in 2006. Any disability (dichotomous variable) and 6 different types of disability were analyzed on the bases of their relationship with income quintiles, occupational status, educational level, and material living standards (quality of the housing, overcrowding rate and sanitary conditions). Confounding and interaction effects were explored using R statistical program. Income, education, occupation, and material measures of socioeconomic position, along with some sociodemographic characteristics of the population, were independently associated with the chance of being disabled in Chile. Interestingly, classic measures of socioeconomic position (income, education, and occupation) were consistently associated with any disability in Chile, whereas material living conditions were partially confounded by these classic measures. In addition to this, each type of disability showed a particular pattern of related social determinants, which also varied by age group. This study contributed to the understanding of disability in Chile and how different domains of socioeconomic position might be associated with this prevalent condition. Disability remains a complex multidimensional public health problem in Chile that requires the inclusion of a wide range of risk factors, of which socioeconomic position is particularly relevant.

    Medical graduates face different postgraduate training options, but their priority is to obtain a primary medical specialty, defined as a specialty that does not derive from other. There are different specialty training programs in Chile, which can be dependent or independent of the Ministry of Health. The information about these programs is available in different Internet sites. However a centralized information service that groups and synthetize these programs is lacking, hampering graduate choice decisions. This article aims to review all specialization program modalities, providing a general vision of the institutional structure and implications that govern the specialization process in Chile.

Verificou-se a ocorrência de variabilidade genética por meio de isoenzimas e RAPD, porém não foi observada a similaridade entre os dendrogramas obtidos por ambos os tipos de marcadores, sugerindo que as isoenzimas forneceram menos informação sobre o genoma. A maior eficácia do RAPD foi devida à possibilidade de processar maior número de análises, evidenciando mais detalhes sobre o genoma.

El sector público está formado por todos los organismos que constituyen el Sistema Nacional de Servicios de Salud y cubre aproximadamente a 70% de la población, incluyendo a los pobres del campo y las ciudades, la clase media baja y los jubilados, así como los profesionales y técnicos. El sector privado cubre aproximadamente a 17.5% de la población perteneciente a los grupos sociales de mayores ingresos. Un pequeño sector de la población, perteneciente a la clase alta, realiza pagos directos de bolsillo a proveedores privados de servicios de atención a la salud. Alrededor de 10% de la población está cubierta por otras agencias públicas, fundamentalmente los Servicios de Salud de las Fuerzas Armadas. Recientemente el sistema se reformó creando el Régimen General de Garantías en Salud, que establece un Sistema Universal con Garantías Explícitas que se tradujo, en 2005, en el Plan de Acceso Universal con Garantías Explícitas (AUGE, que garantiza el acceso oportuno a servicios de calidad para 56 problemas de salud, incluyendo cáncer en niños, cáncer de mama, trastornos isquémicos del corazón, VIH/SIDA y diabetes.This paper describes the Chilean health system, including its structure, financing, beneficiaries, and its physical, material and human resources.

    Chile hosts some of the sunniest places on earth, which has led to a growing solar energy industry in recent years. However, the lack of high resolution measurements of solar irradiance becomes a critical obstacle for both financing and design of solar installations. Besides the Atacama Desert, Chile displays a large array of "solar climates" due to large latitude and altitude variations, and so provides a useful testbed for the development of solar irradiance maps. Here a new public database for surface solar irradiance over Chile is presented. This database includes hourly irradiance from 2004 to 2016 at 90 m horizontal resolution over continental Chile. Our results are based on global reanalysis data to force a radiative transfer model for clear sky solar irradiance and an empirical model based on geostationary satellite data for cloudy conditions. The results have been validated using 140 surface solar irradiance stations throughout the country. Model mean percentage error in hourly time series of global horizontal irradiance is only 0.73%, considering both clear and cloudy days. The simplicity and accuracy of the model over a wide range of solar conditions provides confidence that the model can be easily generalized to other regions of the world.

    Full Text Available RESUMO: A utilização de bioestimulantes pode auxiliar a mitigar os prejuízos ao milho, ocasionados pela má qualidade de estande. Este trabalho foi conduzido objetivando avaliar o efeito do tratamento de sementes com bioestimulante sobre o desempenho agronômico do milho, submetido a diferentes níveis de variabilidade na distribuição espacial das plantas na linha de semeadura. O experimento foi implantado em Lages, SC, durante o ano agrícola de 2013/2014. O delineamento experimental foi de blocos ao acaso, dispostos em parcelas subdivididas. Nas parcelas principais, testaram-se três níveis de desuniformidade espacial na linha: 0, 50 e 100% do Coeficiente de Variação (CV. No nível 0 % de CV, todas as sementes foram uniformemente distribuídas no sulco de semeadura, a uma distância de 17cm entre si. Nos demais níveis de CV, as distâncias entre sementes variaram conforme o tratamento. Nas subparcelas, testou-se a presença ou ausência do tratamento de sementes com bioestimulante. O aumento da variabilidade na distribuição espacial das plantas reduziu a área foliar e o teor de clorofila da folha índice no espigamento, bem como o diâmetro do colmo na colheita, independentemente do tratamento de sementes com bioestimulante. Isso contribuiu para reduzir o número de grãos por espiga e o rendimento de grãos dos tratamentos com 50 e 100% de CV na variabilidade espacial, tanto na presença quanto na ausência do bioestimulante. Portanto, o tratamento de sementes com bioestimulante não mitigou os prejuízos ao rendimento de grãos do milho ocasionados pela distribuição espacial irregular das plantas na linha de semeadura.

    Full Text Available Este trabalho teve como objetivo avaliar a variabilidade físico-química da farinha de mandioca comercializada no município de Cruzeiro do Sul - AC por meio da análise multivariada. Foram analisadas 18 amostras de diferentes farinhas de mandioca, quanto às variáveis: umidade, cinzas, lipídios, proteína bruta, fibra bruta, carboidratos totais, acidez e pH. A aplicação da análise multivariada de agrupamento segundo o método de Tocher permitiu o estabelecimento de cinco grupos de farinhas. Os grupos IV e V foram considerados de alta qualidade, o primeiro por apresentar o menor teor de cinzas e o maior de proteína bruta, e o segundo por apresentar o menor teor de umidade e o maior teor de carboidratos dentre os grupos. As técnicas de análise multivariada foram coerentes para identificar as farinhas mais heterogêneas. A identificação de grupos distintos indica a existência de variabilidade nas farinhas de mandioca comercializadas na região de Cruzeiro do Sul - AC, podendo esta variabilidade estar relacionada, especialmente com o processo de produção.The goal of this work was to evaluate the physicochemical variability of the cassava flour, sold in the city of Cruzeiro do Sul - in the state of AC (Brazil, by multivaried analysis. The following contents of eighteen different cassava flours were analyzed: moisture, ashes, lipids, protein, fiber, carbohydrates, acidity, and pH. Grouping multivaried analysis according to the Tocher method allowed the establishment of five groups of flours. The groups IV and V were considered high quality groups. The first one due to the lower ashes and higher protein contents; and the second due to the lower moisture and higher carbohydrates contents. The multivaried analysis techniques presented good responses to identify most heterogeneous flours. The physicochemical variability seen in the five different groups probably indicates different production processes.

O presente estudo avaliou a variabilidade e a repetibilidade para caracteres biométricos de frutos e sementes e qualidade de sementes entre árvores matrizes de C. speciosa. Foram coletados frutos de 36 árvores matrizes, determinando-se em cinco frutos o diâmetro, comprimento, massa fresca e seca e número de sementes e em 100 sementes, o comprimento, diâmetro e peso de 100 sementes. A qualidade fisiológica das sementes foi avaliada pela germinação e testes de vigor: índice de velocidade de germinação, envelhecimento acelerado (EA, condutividade elétrica (CE e submersão das sementes em água, em quatro repetições de 25 sementes, exceto para CE e submersão, em que as repetições continham 40 sementes. Após os testes de EA e submersão, as sementes foram submetidas ao teste de germinação. As médias de árvores matrizes foram comparadas pelo teste de Scott-Knott e estimou-se o coeficiente de determinação genotípico, repetibilidade e correlação entre caracteres. As características avaliadas apresentam variabilidade significativa entre as árvores matrizes e estão sob baixa influência ambiental. As correlações entre caracteres biométricos com o processo germinativo e qualidade de sementes são baixas. Os coeficientes de repetibilidade são altos e a avaliação de cinco frutos e 100 sementes por árvore matriz e o uso de quatro repetições nos testes de germinação e vigor possibilitam boa confiabilidade na determinação da variabilidade da espécie.

    2015-01-01

    Full Text Available Previous studies have pointed out the convenience of taking the characteristics of the skill to be learned and the intrinsic characteristics of the learners into account when designing practice tasks. Nevertheless, few studies have manipulated the amount of variable practice. The ability to adapt, as an inherent feature of biological systems, can be an adequate framework to explain and predict motor learning processes. This paper is based on adaption processes explained under the theory of allostasis and the general adaption syndrome and shares the background of the Dynamic Systems Theory, to propose the concept of practice load as a useful tool to quantify variability of practice in motor learning. From this standpoint, the conditions of variable practice are reviewed to be a stimulus in an adequate magnitude and direction to take the learner to a higher level of performance and hence to optimize motor learning. Resumen Muchos autores han recomendado la conveniencia de ajustar los niveles de práctica variable teniendo en cuenta las características de la tarea y la variabilidad intrínseca que muestra el aprendiz en la ejecución de la habilidad. Sin embargo, no son numerosos los trabajos que han manipulado varios niveles de cantidad de variabilidad al practicar. La capacidad de adaptación, como rasgo de los sistemas biológicos puede resultar un marco adecuado para afrontar esta cuestión. En este trabajo, apoyado en los procesos de adaptación explicados bajo las teorías de alostasis y el síndrome general de adaptación (GAS, y bajo presupuestos compartidos por la Teoría General de Sistemas Dinámicos, propondrá el concepto de carga de práctica como una herramienta para cuantificar la práctica en el aprendizaje motor. Bajo esta perspectiva se revisan las condiciones en las que la práctica en variabilidad debe modularse, para suponer una estimulación que facilite al aprendiz una adaptación a un nivel de rendimiento superior y con

    Migration is a growing phenomenon in Latin America influenced by several factors such as economic stability, employment, social welfare, education and health system. Currently Chile has a positive migration flow rate. Particularly, a significant number of Haitian immigrants has been observed du ring the last years, especially after earthquake of 2010. These immigrants present a different cultural background expressed in relevant aspects of living including parenting and healthcare. Knowing the Haitian culture and its health situation is relevant for a better understanding of their health needs. Haitian people come to Chile looking for a cordial reception and willing to find a place with better perspectives of wellbeing in every sense. Immigration represents a major challenge for Chilean health system that must be embraced. Integration efforts in jobs, health, education system and community living should be enhanced to ensure a prosper settlement in our country. A new immigration law is crucial to solving major problems derived from current law created in 1975.

To determine the prevalence of Common Mental Disorders (CMD) among immigrants who live in Independencia, a quarter in Santiago, Chile. A cross sectional study was carried out in the primary health care clinic and in the state-funded school of Independencia. A representative sample of 282 adults and 341 children were interviewed. Mental disorders were diagnosed using CIS-R and MINI structured interviews. The interviewed immigrants came mostly from Peru. The prevalence of mental disorders in the adult population was 17.8% and among children, it was 29.3%. The adult immigrants have a lower prevalence of mental disorders than the Chilean population but it increases among children. Barriers of access to health services, that should be solved, were detected.

    There is a battle on in Northern Chile to supply the region with gas and electricity. Two pipelines and a transmission line are being built, but there is insufficient demand to merit the construction of all of these projects. It is widely believed that the first pipeline to be finished will be the overall winner, but the situation is not that simple. A more sensible conclusion could be the merger of the two pipeline projects, rationalising supply of gas to the region. (Author)

    In September 2000, an expert mission was assigned to Chile, under the regional project named 'International BBS in Medical Practices Radiation Protection and Quality Assurance In Interventional Radiology' (ARCAL XLIX). The objective of the mission was to evaluate the level of radiation protection (RP) and safety in interventional cardiology ( IC ) installations. A team of local cardiologists, medical physicists and technologists was created for this purpose and during one week, several cardiology laboratories were evaluated and some basic quality controls (QC) were carried out. A basic pilot training course in radiation protection was imparted at the Hospital of the University of Chile in Santiago de Chile and some of the key objectives for a future national quality assurance programme were presented during the national congress of IC. In addition, a national survey on radiation protection aspects was circulated and its results evaluated. These activities enabled the local team to become familiar with the methodology of assessment of the level of protection and the organization of a programme, which was illustrated with the examples of similar European programmes. As result of these actions, several proposals were made to both the local authorities and the IAEA. The most important were: a) to initiate a basic QC programme, b) to organize a training in RP for cardiologists in order to formalize their accreditation, c) to improve personal occupational dosimetry, d) to initiate a programme of patient dosimetry, e) to optimize the technical and clinical protocols, f) to create a national registry of incidents with skin injuries.

Este archipiélago está conformado por tres islas: Robinson Crusoe-Santa Clara (RC-SC y Alejandro Selkirk (AS. Las islas RC-SC se encuentran en una región de alta energía cinética y mayores concentraciones de clorofila-α definida como Zona de Transición Costera, en cambio la isla AS se encuentra en una región de baja energía cinética y menores concentraciones de clorofila-α denominada Zona Oceánica.

En ambas islas el ciclo anual de la clorofila es significativo y comienza a incrementar en abril, alcanzando valores relativamente altos entre junio y noviembre, disminuyendo hacia diciembre, hasta alcanzar un mínimo hacia fines de marzo. Este ciclo anual aparece desacoplado con el viento y acoplado con la energía cinética. Incrementos invernales de clorofila-a aparecen vinculados con remolinos de mesoescala provenientes de la zona continental, mientras que incrementos primaverales se podrían asociar a procesos locales vinculados al "efecto masa de isla".

    To identify those institutions granting medical research in Chile, every issue of Revista Médica de Chile published between 1987 and 1994 was reviewed, under the assumption that a vast majority (over 70%) of papers released by Chilean authors in topics of internal medicine and related subspecialties would have been submitted for publication in this journal. This assumption was based in the solid prestige of Revista Médica de Chile among Chilean physicians and investigators: it is one of the oldest medical journals in the world (founded in 1872) and its inclusion in the most important international indexes (e.g. Index Medicus, Current Contents) qualifies it in the "mainstream literature". Papers classified as "Original Articles", "Clinical Experiences", "Review Articles", "Public Health", "Case Reports", "Clinical Laboratory", "Special Articles" and "Medical Education" were screened for acknowledgment of financial support beyond the resources needed for routine clinical work. Among 1,528 manuscripts published, 344 were "Original Articles" and 61.3% of them acknowledged special financial support. Five hundred and one manuscripts were "Clinical Experiences" and 21.5% of them received special financial support; similar proportions were detected in "Review Articles" and "Public Health" topics. The institution ranked as providing support most often was the "Fondo Nacional de Ciencias y Tecnología" (FONDECYT), a governmental fund that assigns resources to research in all areas of science and technology through a peer-reviewed nationwide annual contest. FONDECYT was identified as provider of financial support to 45.2% of the "Original Articles" and "Clinical Experiences"; Chilean universities were mentioned by 33.6% and other entities (including pharmaceutical companies, other national and foreign organizations) by 23.1%. The University of Chile was the main Chilean university mentioned in the acknowledgments. The proportion of papers receiving special financial support

    Children and young international migrants face different health challenges compa red with the local population, particularly if they live in insecure environments or adverse social conditions. This study seeks to identify gaps in health outcomes of children between immigrant and local population in Chile. This study analyses data from three sources: (i) Born in Chile: Electronic records of antenatal visits from all municipal antenatal clinics of Recoleta in 2012; (ii) Growing up in Chile: Population survey "National Socioeconomic Characterization" (CASEN) from 2013 and (iii) Getting sick in Chile: Data of all hospital discharges in 2012, provided by the department of statistics and health information (DEIS) of the Ministry of Health. (I) Born in Chile: Im migrants more frequently have psychosocial risk (62.3% vs 50.1% in Chileans) and enter later into the program (63.1% vs 33.4% enter later than 14 weeks of pregnancy). All birth outcomes were better among immigrants (e.g. caesarean sections rates: 24.2% immigrants vs % Chileans). (ii) Growing up in Chile: A higher proportion of migrant children is outside the school system and lives in multidi mensional poverty (40% immigrants vs 23.2% Chileans). (iii) Getting sick in Chile: Injuries and other external causes were more frequent cause of hospitalisation among migrants (23.6%) than the local population (16.7%) aged between 7 and 14 years. Addressing the needs of the children in Chile, regardless of their immigration status, is an ethical, legal and moral imperative.

    Chile is a country with an incipient HIV epidemic. Just as in other countries, disadvantaged groups in Chile are contributing to the increased incidence of the disease. The Mapuche indigenous population is one such group that has been affected by the spread of HIV. However, no prevention programs are tailored to the culturally specific needs of this community. In recognition of this discrepancy, an academic-community partnership was formed to develop an HIV educational module for a Mapuche community. The module was developed for use as part of an already established health-related program. The aims of the module were to identify perceptions about HIV among Mapuches and present information specific to HIV and its prevention. Focus was placed on cultural sensitivity. The module was carried out in connection with a first-aid course in an attempt to increase effectiveness of the intervention by working jointly with an established community program. Sixteen (16) Mapuches participated voluntarily and demonstrated some knowledge regarding HIV, but they lacked an overall understanding as to how it is transmitted and why prevention strategies are affective. Participants correctly identified sexual contact as a means of transmission, but when asked why, one person stated, “I just know it, I read it.” There were significant barriers to communication within the group, secondary to cultural practices related to age and gender. Major obstacles in controlling HIV are the lack of prevention strategies targeted to disadvantaged groups. The module developed for this intervention was the first effort of the Academic Community Partnership established between the Pontificia Universidad Católica de Chile and the Mapuche group around HIV prevention. Continued collaboration between academia and affected communities as well as incorporating HIV information into established programs are effective strategies for delivering prevention information to disadvantaged populations and for

La primera parte del artículo provee un resumen histórico del crecimiento y consolidación de la religión Pentecostal en relación a diferentes ambientes políticos. En este artículo se esclarecen además las diferentes posturas Pentecostales hacia la esfera política. En particular hago hincapié, en cómo surge una cultura de desencanto político en el Chile post-dictatorial que crea un vacío simbólico, el cual trae como consecuencia el nacimiento de movimientos religiosos. En la segunda parte de este artículo se discute las posibles afinidades entre el Pentecostalismo, como una cultura religiosa, y los principios democráticos. El argumento es que a pesar de que el Pentecostalismo puede contener algunas cualidades democráticas, también existe una compatibilidad notable entre la visión teísta e individualista Pentecostal acerca de los cambios sociales, y un orden social neoliberal, en donde la indolencia política se expande y en donde predomina un sentido de progreso individual y no colectivo.

    Lange, Carina B.; Ulloa, Osvaldo

    The Humboldt Current System, with its coastal upwelling ecosystem off Peru and Chile, is one of the most productive marine systems in the world. Here, significant exchange of heat and CO2 takes place between the ocean and the atmosphere due to upwelling of sub-surface, cold, nutrient-rich, CO2-saturated waters. In addition, the eastern South Pacific holds one of the three most important oxygen minimum zones of the global ocean. Through the biologically mediated process of denitrification, the oxygen minimum zone contributes to the global sink of nitrogen in the ocean and as a source of the greenhouse gas N2O to the atmosphere.

    Bringing together more than 170 years of data, this study represents the first attempt to construct a species checklist and analyze the diversity and distribution of testate amoebae in Chile, a country that encompasses the southwestern region of South America, countless islands and part of the Antarctic. In Chile, known diversity includes 416 testate amoeba taxa (64 genera, 352 infrageneric taxa), 24 of which are here reported for the first time. Species-accumulation plots show that in Chile, the number of testate amoeba species reported has been continually increasing since the mid-19th century without leveling off. Testate amoebae have been recorded in 37 different habitats, though they are more diverse in peatlands and rainforest soils. Only 11% of species are widespread in continental Chile, while the remaining 89% of the species exhibit medium or short latitudinal distribution ranges. Also, species composition of insular Chile and the Chilean Antarctic territory is a depauperated subset of that found in continental Chile. Nearly, the 10% of the species reported here are endemic to Chile and many of them are distributed only within the so-called Chilean biodiversity hotspot (ca. 25° S-47° S). These findings are here thoroughly discussed in a biogeographical and evolutionary context. Copyright © 2015 Elsevier GmbH. All rights reserved.

    Full Text Available Along the coast of central Chile, geographic trends of diversity have been inferred from literature compilations and museum collections based on species range limits for some taxonomic groups. However, spatially-intensive field-based assessments of macrobenthic species richness are largely missing. Over the course of a multiyear study (1998-2005, we characterized latitudinal patterns of rocky intertidal diversity at 18 sites along the coast of central Chile (29-36° S. At each site, the number of sessile and mobile macrobenthic species was quantified in 0.25 m² quadrats. Two estimators of local (alpha diversity were used: observed local species richness, calculated from the asymptote of a species-rarefaction curve, and the Chao2 index, which takes into account the effect of rare species on estimates of local richness. We identified a total of 71 species belonging to 66 genera for a total of 86 taxa. The most diverse groups were herbivorous mollusks (27 taxa and macroalgae (43 taxa. Diversity showed a complex spatial pattern with areas of high species richness interspersed with areas of low richness. In accordance with previous work, we found no trend in the number of herbivorous mollusks and an inverse and significant latitudinal gradient in the number of algal species. Our results highlight the need for taxonomically diverse assessments of biodiversity of the dominant taxa that conform intertidal communities.A lo largo de la costa de Chile central, los patrones geográficos de diversidad han sido inferidos a partir de revisiones literarias y colecciones de museos para algunos grupos taxonómicos. Sin embargo, aun no contamos con una evaluación integral, y en terreno, de la riqueza de especies macrobentónicas intermareales. En un estudio de largo plazo conducido entre 1998 y 2005 caracterizamos los patrones latitudinales en la biodiversidad del intermareal rocoso en 18 sitios a lo largo de la costa de Chile central (29-36° S.

    In response to the progressive environmental deterioration, the Ecological Society of America has made a proposal, called "Sustainable Biosphere Initiative", to do research, teaching and decision making processes on biodiversity, global change and the effects of human activities on environment. The goal of appropriate environmental protection and welfare for mankind includes health and quality of life. Presently, Chile faces a number of environmental problems such as pollution, excessive urban growth, loss of agricultural areas, disposal of solid waste and species extinction. The lack of education and information in Chile, on these problems, is worrisome. The role of universities to overcome this deficit should be crucial in the future sustainable development of Chile.

    Full Text Available Euphorbia heterophylla, também conhecida como amendoim-bravo ou leiteira, é considerada planta invasora importante em mais de 56 países, inclusive no Brasil, tendo acarretado perdas de até 33 % na cultura da soja. Fenotipicamente, é uma espécie de características variáveis, especialmente em relação ao formato do limbo foliar. Esta variabilidade fenotípica tem sido utilizada para diferenciar e classificar as plantas, sugerindo a vários autores que a leiteira seria, de fato, constituída por diferentes espécies. Para estudar a variabilidade genética a nível de DNA entre plantas de Euphorbia heterophylla, que apresentam folhas morfologicamente diferentes, foram analisadas dez plantas diferentes coletadas em campos de soja, em Londrina/PR. As plantas foram transplantadas para casa-devegetação e o DNA das folhas foi extraído para análise pela técnica de RAPD. Vinte seis diferentes "primers", de dez nucleotídeos de sequência aleatória, geraram total de 102 bandas de DNA, sendo 38 delas polimórficas. A distância genética entre os indivíduos foi calculada em função da presença e da ausência das bandas, variando de 1 a 39% entre plantas. A análise de agrupamento dividiu as plantas em dois grupos, considerando limite de distância relativa de 22%. Os grupos gerados separaram nitidamente as plantas quanto ao formato do limbo foliar (estreito ou arredondado e quanto á ramificação (densa ou normal.Euphorbia heterophylla is an important weed affecting the performance of annual and perennial crops.

    2016-04-01

    Guided wave dispersion is observed in subduction zones as high frequency energy is retained and delayed by low velocity structure in the subducting slab, while lower frequency energy is able to travel at the faster velocities associated with the surrounding mantle material. As subduction zone guided waves spend longer interacting with the low velocity structure of the slab than any other seismic phase, they have a unique capability to resolve these low velocity structures. In Northern Chile, guided wave arrivals are clearly observed on two stations in the Chilean fore-arc on permanent stations of the IPOC network. High frequency (> 5 Hz) P-wave arrivals are delayed by approximately 2 seconds compared to the low frequency (young subducting lithosphere also has the potential to carry much larger amounts of water to the mantle than has previously been appreciated.

    Avian influenza (AI) was diagnosed in May 2002 for the first time in Chile and South America. The epidemic was caused by the highly pathogenic AI (HPAI) virus subtype H7N3 that emerged from a low pathogenic virus. The index farm was a broiler breeder, located in San Antonio, V Region, which at the time was a densely populated poultry area. Stamping of 465,000 breeders, in 27 sheds, was immediately conducted. Surveillance activities detected a second outbreak, 1 wk later, at a turkey breeding farm from the same company. The second farm was located 4 km from the index case. Only 25% of the sheds were infected, and 18,500 turkeys were destroyed. In both outbreaks, surveillance zones and across-country control measures were established: prediagnosis quarantine, depopulation, intensive surveillance, movement control, and increased biosecurity. Other measures included cleaning, disinfection, and controlling the farms with sentinels to detect the potential presence of the virus. Zoning procedures were implemented to allow the international trade of poultry products from unaffected areas. Positive serologic results to H5N2 virus also were detected in other poultry farms, but there was no evidence of clinical signs or virus isolation. Epidemiological investigation and laboratory confirmation determined that positive serology was related to a contaminated imported batch of vaccine against inclusion body hepatitis. All actions taken allowed the control of the epidemic, and within 7 mo, Chile was free of AI. Epidemic and control measures that prevented further spread are described in this article, which illustrates the importance of a combination of control measures during and after an outbreak of AI. This study is a good example of how veterinary services need to respond if their country is affected by HPAI.

Sin embargo este grupo de anfípodos no ha sido muy bien estudiado en la costa chilena. El estudio de los caprélidos se ha visto dificultado por su gran variabilidad morfológica y el hecho de que la literatura así como los especímenes de los museos son difíciles de localizar. El objetivo de este estudio fue entregar las herramientas taxonómicas para la identificación de las especies de crustáceos caprélidos comunes en el centro-norte de la costa de Chile. Se muestrearon distintos hábitats (boyas, bolones intermareales, praderas de algas y fanerógamas marinas y se encontraron seis especies distintas de caprélidos: Caprellina longicollis (Nicolet, 1849, Caprella equilibra Say, 1818, C. scaura Templeton, 1836, C. verrucosa Boeck, 1871; Deutella venenosa Mayer, 1890 y Paracaprella pusilla Mayer, 1890. Caprella scaura, C. verrucosa y D. venenosa fueron muy abundantes sobre las algas, hidrozoos y briozoos asociados a boyas. Caprella equilibra, también presente en boyas, fue más abundante bajo piedras en zonas intermareales rocosas expuestas, donde también se encontraron ejemplares de D. venenosa y de P. pusilla. Caprella scaura también se encontró sobre algas rojas de las playas arenosas, especialmente sobre Gracilaria chilensis y sobre la fanerógama marina Heterozostera tasmanica, donde cohabitó junto a Caprellina longicollis. Paracaprella pusilla constituye una nueva cita para las costas pacíficas sudamericanas, siendo nueva para la fauna de Chile.

Assim, a escolha de um dos processos, para aplicação específica deveria considerar como tais particularidades afetam a qualidade destas soldas. Para subsidiar esta escolha, o presente estudo teve como objetivo investigar como a mudança na corrente média afeta a estabilidade e a regularidade das transferências de metal em soldas realizadas com tensão constante e corrente pulsada e comparar a variabilidade da geometria e da diluição destas soldas. Para atingir estes objetivos foram realizadas soldas automatizadas, tendo como metal de base o aço ABNT 1020 e como metais de adição o arame AWS ER70S-6 e AWS E71T-1. Além das soldas com variação da corrente média, os testes envolveram a determinação dos parâmetros para a ocorrência de transferência estável por curto-circuito, goticular e pulsado. Os resultados mostraram que a tensão que determina a maior estabilidade na transferência pelo modo curto-circuito, independe da velocidade de soldagem e aumenta com a velocidade do arame, mostraram também que as soldas com arame tubular apresentaram maiores variabilidades comparadas ao arame maciço.

    Full Text Available This study aimed to characterize the genetic variability in commercial accessions of passion fruit from the Federal District, Brazil, by RAPD markers. Genetic analyses were done with leaf samples of 30 accessions. DNA samples were amplified by RAPD technique, and respective markers converted into a binary matrix, from which the genetic distances between the accessions were estimated. Clustering analyis based on genetic distances allowed to detect a wide range of genetic variabillity among the accessions of sour passion fruit, and to separate them from the two sweet passion fruit. The graphical positioning of 'BRS Ouro Vermelho' confirms its potential to improve the genetic variability of commercial varieties of sour passion fruit. Dispersal of genetic distances among commercial accessions of sour passion fruit supports evidence for different genetic origins of the materials planted in the Federal District. The verified genetic variability indicates the potential success of future breeding programs for this region.Este estudo teve como objetivo caracterizar a variabilidade genética de acessos de maracujá comerciais no Distrito Federal por meio de marcadores RAPD.

    Full Text Available Resumo Tradicionalmente, na aprendizagem de habilidades motoras a prática tem sido estruturada de forma constante, em blocos, seriada ou aleatória. Tem sido proposta a superioridade da prática variada sobre a prática constante bem como da prática aleatória e seriada sobre a prática em blocos. Atualmente tem sido observada uma especificidade do tipo de prática: a prática constante auxilia na formação de uma estrutura de movimento, especialmente no inicio da aprendizagem e a prática variada na melhora da parametrização. O presente estudo investigou diferentes regimes de prática e a sua combinaçao numa sequência que fornece um aumento gradual de variabilidade (constante, blocos e aleatório na aquisição de habilidades motoras. A amostra foi distribuida em quatro grupos (n = 10: CCC (constante, BBB (blocos, AAA (aleatório e CBA (constante-blocos-aleatório. O experimenta foi dividido em fase de aquisição e teste de transferência. Na fase de aquisição a tarefa foi pressionar teclas numéricas do teclado de um computador em uma sequência (2, 8, 6, 4 com o dedo indicador, com tempo relativo entre os componentes especificado (22,2%, 44,4% e 33,3% e com os seguintes tempos totais (700, 900 e 1100 ms estabelecidos conforme o delineamento experimental. Os resultados do teste demonstraram superioridade dos grupos CBA e AAA na medida de erro absoluta, dos grupos CCC e BBB na medida de erro relativo e dos grupos CCC, BBB e CBA na medida de variabilidade de erro relativo. Tais resultados demonstram que os regimes de prática que forneceram menor variabilidade conduziram ao aprendizado de uma estrutura de movimento, enquanto que as que forneceram maior variabilidade resultaram na melhora da capacidade de parametrização.

    Full Text Available OBJECTIVE: To examine the association between behavioral problems and tobacco smoking among adolescent students in Chile. METHODS: Data were drawn from a study that included questionnaire surveys of 46 907 school-attending adolescents in all 13 of the administrative regions of Chile. Assessments were based on an adapted, Spanish-language version of the Drug Use Screening Inventory. The conditional form of the logistic regression model was used for analysis, with matching of students on individual schools, and with further statistical adjustments for sex, age, and selected risk factors. RESULTS: The prevalence of tobacco smoking among the adolescents was very high across all of Chile, with a level between 56% and 65% in each of the 13 regions. The estimated odds of tobacco use in youths at the highest level of behavioral problems was about twice that for youths at the lowest levels, both before and after controlling for sex, age, lack of participation in recreational activities, level of irritability, and levels of problems with school, family attention, and mental health. CONCLUSIONS: These findings help to complement and complete the evidence of prior studies on tobacco smoking among adolescents with behavior problems, including recent research on Central American youths. Although the magnitude of observed associations in Chile was not as great as that for the associations found in Central America, both the strength of these associations and their statistical significance were observed throughout Chile. This is the first study in Chile on potentially causal relationships such as these.

    Full Text Available This study analyzes the relationship between the variability in the performance of the flat tennis service and its practice under variable conditions, taking as a starting point a predictive analysis of the instantaneous kinematic variables of the hand that holds the racket. Seventeen tennis players performed services under 8 practice conditions (rackets and balls were modified, and pre-test and post-test were carried out. The players performed 120 services with the instruction to hit the ball powerfully and maintaining maximum efficiency. Data showed that two variables related to the speed and the acceleration of the hand will predict efficacy at 57.7%: both the time variation coefficients until we reach the speed peak and the final acceleration of the hand in the Y axis. Significant differences were also obtained between some instantaneous kinematic variables measured in the pre-test and the practice series, and also negative and significant correlations between these variables and the efficacy of the services.

    1982-01-01

    Prior to 1976, voluntary female sterilization was 1 of the regular family planning services offered in Chile. After that the Ministry of Public Health declared that it could not be considered a fertility regulation activity and could thus be performed only for health reasons. Between 1971-75, there was almost a 6-fold increase in the number of sterilizations performed at the Valdivia Regional Hospital, with a rise to 2400 procedures. Such an unprecedented increase in voluntary sterilization prompted this study. The results are based on a 1976 survey of women sterilized between 1971-75 at the Valdivia Regional Hospital. Personal interviews were conducted. The number of voluntary sterilizations there during the aforementioned period showed a sustained upward trend; the number of births increased only moderately during that time. The data on sterilization in the Valdivia area is compared to that collected by the Santiago study. Age, marital status, place of origin or residence, education, and religion were compared. Socioeconomic and occupational data were also examined. 9 of 10 women in Valdivia were from low-income families. This agrees closely with the Santiago data. About 1/4 of the women in both samples were employed outside the home. Also in both samples, about 1/2 of the spouses of sterilized women were blue collar workers; only 1/5 or less were white collar, and very few were professionals. About 52% in Valdivia and 45% in Santiago had borne 7 or more viable offspring. The average number of spontaneous abortions was also similar. A significantly higher percentage (P0.01) of Valdivia women used contraceptives. There are some general trends apparent in both groups as to the reasons for sterilization; most were prompted by difficult socioeconomic conditions. 37.9% of the Santiago women felt their families were complete and 27.3% of the other group cited the same reason. Other reasons were medical, failure of contraception, problems with spouse, and other. Medical

Uma parcela de 50 x 70 m foi amostrada de acordo com uma malha de 5 por 5 m, totalizando 140 pontos. Foram avaliados atributos químicos do solo superficial (0,00-0,20 m e subsuperficial (0,20-0,40 m, sua granulometria e a espessura de solo remanescente (ES - definida como a camada do solo acima do horizonte C, além da produtividade de matéria seca (MS e altura da crotalária juncea (ALTPL. Os valores de atributos maiores ou menores que quatro desvios-padrões da média foram descartados. A colheita da parte aérea da crotalária foi realizada no início de sua floração, em miniparcelas de 2 x 2,5 m, e calculada a matéria seca. A dependência espacial dos atributos estudados foi avaliada por semivariogramas escalonados. Esses apresentaram dependência espacial, com exceção do P (0,00-0,20 m e K nas duas camadas. Os atributos puderam ser agrupados em três categorias homogêneas quanto ao alcance do semivariograma: atributos químicos do solo (12 a 32 m < componentes de planta (25 a 32 m < frações granulométricas (32 a 42 m. Os atributos que melhor explicaram a produtividade da crotalária juncea foram H + Al, valor T e saturação por bases.

    Full Text Available A compreensão da diversidade genética fornece elementos básicos sobre a dinâmica e funcionamento de populações, auxiliando na conservação e uso sustentável das espécies. Supõe-se que populações sucessionais precoces poderiam ser geneticamente mais diferenciadas do que populações sucessionais mais tardias. Visando testar esta hipótese, o presente trabalho teve como objetivo analisar a variabilidade genética de populações de Eugenia uniflora L. em manchas florestais em diferentes estádios sucessionais. Foram selecionadas duas áreas em diferentes estádios de sucessão, sendo a primeira em estádio inicial e a segunda em estádio avançado. A área de estudo apresenta um remanescente florestal em transição de Floresta Ombrófila Mista e Floresta Estacional Semidecídua. Por meio da técnica de RAPD (Random Amplified Polymorphic DNA e análise multivariada, a diversidade gênica esperada e a porcentagem de loci polimórficos foram estimadas, além da similaridade genética entre as populações de cada mancha florestal e a diversidade de cada área por meio do índice de diversidade de Simpson. Os resultados indicaram 79% de loci polimórficos para a área em estádio avançado e 70% para a área em estádio inicial de sucessão. A similaridade genética entre pares de indivíduos variou entre 0,55 e 0,86 na área em estádio inicial de sucessão e entre 0,45 e 0,78 para a área em estádio avançado. Não houve diferenças significativas entre a diversidade das duas áreas (P = 89. Um escalonamento multidimensional não-métrico indicou menor distância genética entre os indivíduos da área em estádio inicial. Da mesma forma, uma análise de similaridade - ANOSIM indicou separação entre os indivíduos das duas áreas.

    Full Text Available O conhecimento da variabilidade dos atributos físicos do solo é importante para o monitoramento da qualidade do solo, pois eles estão diretamente relacionados com a sustentabilidade da produção agrícola. Este estudo teve como objetivos avaliar e identificar as estruturas de dependência espacial, por meio da construção de semivariogramas, num Latossolo Vermelho-Amarelo (LVA, sob lavoura cafeeira; caracterizar as distribuições espaciais dos atributos físicos pela krigagem ordinária; e identificar a camada com maior impedimento físico. O experimento foi conduzido num LVA textura muito argilosa na Fazenda da Empresa de Pesquisa Agropecuária de Minas Gerais, em Patrocínio, MG. A amostragem foi realizada em trincheiras confeccionadas nas intersecções de uma malha retangular de 40 x 150 m, perfazendo um total de 28 pontos, de onde foram coletadas amostras indeformadas em anéis metálicos de 2,54 cm de altura e 6,30 cm de diâmetro, com auxílio do amostrador tipo Uhland. Cada trincheira possuía três degraus de 2,0 x 1,5 m de superfície, nas camadas de 0,00; 0,10; e 0,25 m, onde se coletaram sete amostras indeformadas em cada degrau, dispostas em forma matricial, totalizando 588 amostras. Os atributos físicos do solo apresentaram estrutura de dependência espacial em todas as camadas, exceto a porosidade total. A técnica de krigagem ordinária demonstrou ser alternativa viável para a estimativa de dados em pontos não amostrados na área experimental. A camada de 0,00-0,03 m apresentou maior impedimento físico ao crescimento de raízes, por apresentar maior densidade e menor macroporosidade do solo.

    The increasing prevalence of childhood obesity in Latin America has become a cause for concern. The IAEA has worked closely with the Institute of Nutrition and Food Technology (INTA) at the University of Chile since 1997 to address the problem of malnutrition in the country. In Santiago, the Laboratory of Energy Metabolism and Stable Isotopes was established in 1998 with the help of the IAEA to provide an isotope ratio mass spectrometer and training in the use of stable isotope techniques to assess body composition, infant feeding practices and total daily energy expenditure.

    Data from the Ministry of Health show that in Chile in 2004, 17% of the population had some form of depression, and mood disorders are the tenth cause of disability-adjusted life years (DALY) loss. To determine consumption of antidepressants (ADs) in Chile from 1992 to 2004. National sales data were obtained from the company IMS Health Chile and converted into defined daily doses (DDDs) per 1,000 inhabitants per day. Available ADs were classified in four pharmacological groups (i.e., serotonin-norepinephrine reuptake inhibitors, SNRLs; selective-serotonin reuptake inhibitors, SSRLs; tricyclic antidepressants, TCAs; and others). Total economic burden of ADs utilization and cost per DDDs were also calculated. Trends over time were analyzed using Pearson-R2. Total ADs consumption in Chile measured by DDDs per 1,000 inhabitants per day (DHD) increased linearly (y =0.901x + 1.9129; R2 =0.9296; p economic burden of ADs in Chile (total cost of DDDs consumed) increased from US$65.4 million in 2001 to US$74.6 million in 2004 (14% increase). Average cost per DDD of all AD increased linearly, however not significantly from US$ 0.94 in 2001 to US$ 1.04 in 2004 (y =0.0362x + 0.8784; R2 =0.7382; p =0,262). DDDs per 1,000 inhabitants per day increased linearly over 470% from 1992-2004. SSRLs were the most commonly consumed drugs in Chile. Future research should evaluate the cost-effectiveness of antidepressants in Chile, comparing the results with drug utilization, and determining if unnecessary expenditures have been paid out.

    This study analyzed psychosocial variables of sexual satisfaction in Chile using data from the COSECON survey. Participants were 5,407 subjects (2,244 min and 3,163 women, aged 18-69 years). We used a cross-sectional questionnaire with a national probability sample. Data were collected using a thorough sexual behavior questionnaire consisting of 190 face-to-face questions and 24 self-reported questions. A single item included in the COSECON questionnaire assessed sexual satisfaction. Results showed that high education level, marital status, and high socioeconomic levels were associated with sexual satisfaction in women but not in men. The results also showed important gender differences and sustain the idea that sexuality changes may be more present in middle and high social classes. The proximal variables typically used for measuring sexual satisfaction, such as the frequency of sexual intercourse and orgasm, showed a positive but smaller association with sexual satisfaction. Other important variables related to sexual satisfaction were being in love with the partner and having a steady partner. The results confirmed previous findings and are discussed in the frame of approaches like the exchange, equity, and sexual scripts theories.

    The purpose of the present study was to determine the protein quality and digestibility of shellfish commonly consumed in Chile, and to estimate its contribution to the protein needs of the Chilean population. The shellfish studied were chorito (Mytilus edulis chilensis), macha (Mesodesma donacium), loco (Concholepas concholepas), cholga (Aulacomya ater), erizo (Loxechinus albus) and almeja (no specific variety). The NPU method was used to determine protein quality. The percentage of protein adequacy for adult rations was calculated according to FAO/WHO 1973. The contribution of shellfish to the protein availability according to the family income of the Santiago population, was also calculated. Most of the shellfish presented NPU values of about 70; the lowest values were found for loco (54.9) and macha (63.3). The apparent and true digestibility gave an average of 83.6 and 90.4, respectively. The percentage of protein adequacy of habitual rations ranged between 27% (erizo) and 58% (loco). The availability of shellfish protein in relation to total protein increased from 0.4 to 2.5% when income increased. It is concluded therefore, that shellfish protein is, in general, of good quality. Nevertheless, it might be considered of poor influence insofar as fulfilling the protein needs of the population studied, whatever its socioeconomic level.

  15. Social Networks and Political Parties in Chile

    Adler Lomnitz, Larissa

    2002-09-01

    Full Text Available This paper describes the origin and evolution of two Chilean political parties (the Radical Party and the Christian Democrat Party through the analysis of the social networks that originated and composed them. The aim of this study is to propose a model of national political cultures on the basis of the structure of social networks related to power and of the symbol system, which legitimizes it. The structure of social networks, horizontal and vertical, are based on reciprocal or redistributive forms of exchange, on what is being exchanged and on the articulation between networks. In every society there are symmetrical and asymmetrical exchanges, which produce horizontal and vertical networks. These networks interact among themselves to form the social fabric. The dominance of some over others and how they combine, delineate the character of the political culture (authoritarian vs. egalitarian. Chile is a multiparty country within which there are cohorts of horizontal groups of friends, who informally exercise a central control over their members and create invisible boundaries setting them apart from others, in which leadership is under constrains. The result is both a strong presidential system based on an almost fanatic legitimacy, combined with factionalism and a strong parliamentary system.

    The Mapuche are the largest indigenous group in Chile; yet almost all data on the mental health of indigenous populations are from North America. The study examines the differential DSM-III-R prevalence rates of psychiatric disorders and service utilization among indigenous and non-indigenous community residence. The Composite International Diagnostic Interview (CIDI) was administered to a stratified random sample of 75 Mapuche and 434 non-Mapuche residents of the province of Cautín. Lifetime prevalence and 12-month prevalence rates were estimated. Approximately 28.4% of the Mapuche population had a lifetime, and 15.7% a 12-month, prevalent psychiatric disorder compared to 38.0% and 25.7%, respectively, of the non-Mapuche. Few significant differences were noted between the two groups; however, generalized anxiety disorder, simple phobia, and drug dependence were less prevalent among the Mapuche. Service utilization among the Mapuche with mental illness was low. This is a preliminary study based on a small sample size. Further research on the mental health of indigenous populations of South America is needed.

    2011-07-05

    There have been reports of the presence of bovine tuberculosis (TB) in Chile for more than 100 years. Several prevalence studies have revealed that there is a wide spectrum of disease across the country with certain geographic areas where the disease is endemic through to other geographic areas where infection is sporadic and at very low prevalence. In 2009, this information was used to divide Chile into different geographic zones based on prevalence rates. This will enable the correct actions to be undertaken to reduce the prevalence of TB. Thus the northern part of Chile which has a medium to high prevalence of TB will be categorized as a control zone. In contrast, the southern part of Chile which has a high proportion of the bovine population, has a low prevalence of TB and will be classified as an eradication zone (Paredes, 2008). Although there have been several past attempts to create a national control and eradication program in Chile, none has been successful. A national program is proposed, and outlined in this paper. Progress toward program initiation in 2009 has been difficult, mostly because of the global economic crisis, difficulties in the milk and meat industry, and social and political issues.

    This article analyses and compares the epidemiology of mental disorders and relevant public policies in Chile and Finland. In Chile, a specific mental health law is still lacking. While both countries highlight the role of primary care, Finland places more emphasis on participation and recovery of service users. Comprehensive mental health policies from Finland, such as a successful suicide prevention program, are presented. Both countries have similar prevalence of mental disorders, high alcohol consumption and high suicide rates. In Chile, the percentage of total disease burden due to psychiatric disorders is 13% and in Finland 14%. However, the resources to address these issues are very different. Finland spends 4.5% of its health budget on mental health, while in Chile the percentage is 2.2%. This results in differences in human resources and service provision. Finland has five times more psychiatric outpatient visits, four times more psychiatrists, triple antidepressant use and twice more clinical guidelines for different psychiatric conditions. In conclusion, both countries have similar challenges but differing realities. This may help to identify gaps and potential solutions for public health challenges in Chile. Finland’s experience demonstrates the importance of political will and long-term vision in the construction of mental health policies.

    Full Text Available Frequently, it is possible to differentiate among large and small size camelids when analysing registers from archaeological sites located at the occidental slope of Puna de Atacama. However, larger animals have received most of the attention having less knowledge about the group of small size camelids. In this paper and by using osteometric methods we study this small size later group. On one hand, we analyse different variables that may affect variability among modern alpacas and vicuñas collections. We focus our work on differences among anterior and posterior phalanxes, inter specific variation and sexual dimorphism. On the other hand, we analyse first phalanxes from Tulán-52 (Late Archaic ca. 4500-3800 BP and Tulán-54 (Early Formative ca. 3200-2300 BP characterising their variability through time by comparing current and archaeological samples. Both archaeofaunal assemblages are similar despite their temporal distance. The analyzed specimens correspond to vicuñas denoting the importance of vicuña hunting through time

    In the present work, an assessment of the Physics research capacity in Chile is presented. For this, the period between 2000 and June 2005 has been studied. In this period almost 200 physicists have contributed to scientific production in terms of ISI publications. Amongst these 200, ∼160 correspond to theoretical physicists and only ∼40 to experimental physicists; ∼178 are men and only ∼22 are women. A more detailed analysis shows that ∼160 physicists have at least one appearance in ISI publications per year considering the last 3 years. Ten years ago, a similar criteria (at least one appearance per year in ISI articles, considering mobile three-year periods), the number of active physicists in the Chilean community was estimated at 70. Therefore, the Chilean active physicists' community has doubled in 10 years. There exist 20 centres in which scientific research is developed: 18 university centres, a government institute and a private institute. As regards scientific productivity, both as related to disciplines or research areas, and well as in relation to research centres, it is found that, generally, scientific production, in a particular area in Physics or in a research centre, is directly related to the number of corresponding researchers; that is to say, the percentage of the national productivity in an area or research centre corresponds to its share in the total number of physicists in the country. A geographical analysis shows that 50% of the productivity corresponds to Santiago and 50% to the rest of the country.

    Full Text Available Por casi un siglo, varios autores han analizado los patrones de distribución de la fauna y flora marina del Pacífico de Sudamérica y de la costa de Chile en particular, con el propósito de establecer el número de las unidades biogeográficas presentes. Si bien los patrones generales actuales son relativamente bien conocidos, la mayoría de los estudios se ha enfocado en las discontinuidades distribucionales y en propuestas de clasificación más que en los factores y procesos dinámicos que han formado las unidades espaciales identificadas. Aun en el caso de las clasificaciones, las conclusiones publicadas se basan principalmente en el análisis de uno o pocos grupos seleccionados, y presentan diferencias importantes en los criterios de selección de los grupos, el número de especies involucrado y la metodología usada. Por otra parte, las discrepancias entre estudios específicos tienden a obscurecer un fenómeno relevante y de mayor escala como es la dinámica de las biotas, uno de los aspectos biogeográficos menos conocidos en Chile. En tal contexto, este trabajo presenta una revisión de literatura sobre la biogeografía marina de Chile y sus aspectos asociados, con los siguientes objetivos: (a resumir las características oceanográficas, climáticas y geomorfológicas de la costa continental de Chile; (b discutir 27 clasificaciones biogeográficas publicadas para la costa chilena, analizando los criterios y procedimientos usados por los autores, sus conclusiones principales, y la concordancia entre los estudios; (c evaluar los procesos dispersivos y vicariantes asociados a los desplazamientos y modificaciones de las biotas de la región, en función de los antecedentes disponibles sobre las condiciones existentes y los principales eventos ocurridos durante los períodos Terciario y Cuaternario; y (d proponer un escenario de cambio biogeográfico basado en determinantes históricas y su influencia en la formación, carácter y din

    In recent decades, Chile has become a destination for immigrants from other South American countries, which has significantly impacted public services - particularly the public health system - at the economic, social, and cultural levels. The aim of this paper is to provide substantiated information on issues concerning undocumented immigrants' access to health care in Chile. A qualitative methodology, fundamentally an ethnography of the clinical setting, was used. Results were then analyzed in relation to theories of power asymmetries and interethnic relations. The research results highlight the lack of compliance with existing regulations and the exercise of discretionary personal judgment as barriers to access. It is concluded that in Chile immigrants in general, and undocumented immigrants in particular, are considered to be illegitimate patients.

    Full Text Available ResumenLa gran cantidad de grados de libertad durante la ejecución de un movimiento deportivo permite describir diferentes niveles de variabilidad. En el estudio del lanzamiento de baloncesto ha existido gran interés por conocer las características de la ejecución óptima del lanzamiento, pero son menos los trabajos que se han interesado en investigar la influencia de la variabilidad en el rendimiento. El presente trabajo pretende conocer cómo afecta a la variabilidad de la ejecución la presencia de un oponente y la modificación de la acción previa al lanzamiento. Diez sujetos ejecutaron veinte lanzamientos de tres puntos, diez lanzamientos en situación denominada estándar, y diez en situación de variabilidad. Distintas variables de la técnica de tiro fueron analizadas mediante técnicas de fotogrametría. Las principales diferencias en la variabilidad del lanzamiento entre ambas situaciones se encontraron para el ángulo de salida del balón y la separación de los pies del lanzador. La comparación entre los sujetos de menor y mayor rendimiento determinó que la variabilidad en la altura del salto es mayor en el grupo de menos éxito. La principal conclusión es que las modificaciones del entorno influyen en la variabilidad del movimiento, por lo que dichas modificaciones deben ser consideradas en las tareas de entrenamiento. AbstractThe great amount of degrees of freedom during the execution of a sport movement allows describing different levels of variability in human movement. Several authors have studied biomechanic characteristics of basketball shoot, but few of them have studied influence of variability on shoot task. The present study tries to know the effects of opponent and previous action on shoot variability. Ten subjects executed twenty three points shoot: ten without constraints, and ten in variability situation. Variability of the shoot was measured by photogrammetry. The main differences between situations were

Os parâmetros comprimento e largura média de folhas, altura de planta, diâmetro de copa, peso médio de fruto, peso médio de polpa/fruto, peso médio de 20 frutos e peso médio de polpa por 20 frutos mostraram diferenças quanto a genótipos e épocas. Em acidez, tamanho e largura média de fruto, as diferenças são exclusivas em relação a épocas, sugerindo ações de condições climáticas. A altura é um bom parâmetro tipificador na diferenciação e seleção de genótipos. As condições meteorológicas podem influenciar marcadamente em caracteres tecnológicos (acidez e em medidas dos frutos. Destacaram-se as associações positivas entre comprimento de folhas com tamanho e peso de frutos e as correlações negativas destes com vitamina C; seguida de correlações positivas e significativas de tamanho com largura de frutos. Dos efeitos diretos sobre vitamina C, relacionam-se os efeitos de Brix e diâmetro de copa como positivos. Contudo, nas condições estudadas, as medidas das folhas estão associadas positivamente com tamanho e peso dos frutos e negativamente com vitamina C.

    Full Text Available O trabalho tem como objetivo avaliar as variabilidades climáticas no município de Patos – PB, enfocando tais variações como um meio para compreender futuras mudanças. Para realização deste trabalho utilizou-se dados de temperatura máxima do ar, umidade relativa do ar e totais pluviométricos mensais e anuais no período de 1994 a 2012, da Estação Meteorológica do INMET na cidade de Patos. Como resultado pode-se afirmar que a temperatura do ar máxima anual demonstrou grande variação entre o período estudado, a temperatura máxima absoluta foi incrementada de 7% e a temperatura mínima absoluta sofreu uma redução de 10, podendo acarretar vários problemas socioeconômico, bem como, para a saúde humana. A partir dos dados, verifica-se, também, que a umidade relativa do ar está sendo incrementado ao longo da série estudada, fato que pode estar relacionado com o aumento da temperatura e consequentemente com uma maior evaporação das águas. Sobre os totais pluviométricos anuais, nota-se que os valores estão aumentando gradativamente, sendo que esse aumento pode estar relacionado com o aumento da temperatura, que faz com que se tenha uma maior evaporação e consequentemente uma maior precipitação.Climate variability for Patos city, Paraíba state, BrazilAbstract: The study aims to assess climate variability in Patos – PB city, focusing on such variations as a means to understand future changes.

Os resultados revelaram uma ampla variabilidade genética para o caráter dentro dos grupos estudados. As diferenças observadas entre os genótipos cultivados parecem ocorrer devido a constituição genotípica diferenciada. O grupo silvestre de A. sterilis L. foi, em média, superior aos demais, sendo que a introdução I-325 se destacou pelo alto teor de proteína. O comportamento similar entre as introduções de A. fatua L. pode ser atribuído a coleta de introduções de apenas uma região, o que reduziu a variabilidade genética. Foram encontrados híbridos artificiais entre A. sativa L. x A. sterilis L. com alto teor de proteína e características desejáveis do grupo cultivado.The increased use of oat grains as human food has stimulated plant breeders to select genotypes with high grain quality. This work aimed to identify and characterize genetic variability for total grain protein in cultivated oat and introductions of A. fatua L., A. sterilis L. and hybrid populations from A. sativa L. x A. sterilis L.. The results showed a large genetic variability for the trait in the studied groups. Differences among cultivated oat genotypes may be attributed to different genetic constitution. A. sterilis L. group showed high protein content specially with the introduction of I-325. Genotypes from A. fatua L. showed similar low levels of protein probably because the narrow range of regions sampled in this study.

    Full Text Available The objective of this work was to estimate the genetic variability and divergence among 22 superior rubber tree (Hevea sp. genotypes of the IAC 400 series. Univariate and multivariate analyses were performed using eight quantitative traits (descriptors, including yield. In the univariate analyses, the estimated parameters were: genetic and environmental variances; genetic and environmental coefficients of variation; and the variation index. The Mahalanobis generalized distance, the Tocher agglomerative method and canonical variables were used for the multivariate analyses. In the univariate analyses, variability was verified among the genotypes for all the variables evaluated. The Tocher method grouped the genotypes into 11 clusters of dissimilarity. The first four canonical variables explained 87.93% of the cumulative variation. The highest genetic variability was found in rubber yield-related traits, which contributed the most to the genetic divergence. The most divergent pairs of genotypes are suggested for crossbreeding. The genotypes evaluated are suitable for breeding and may be used to continue the IAC rubber tree breeding program.O objetivo deste trabalho foi estimar a divergência e a variabilidade genética entre 22 genótipos superiores de seringueira (Hevea sp. da série IAC 400.

    The Chilean, Argentinean and Brazilian power matrixes presented in the last two decades a growth of the non-renewable energy sources share, especially fossil sources, mainly in installed capacity and in a lesser degree in energy production. Greenpeace and the European Renewable Energy Council have elaborated a reference energy scenario together with a scenario analyzing the institution of ample measures for the promotion of renewable energy sources. Feed-in tariffs and auction or bidding mechanisms implemented in Brazil and Argentina and the renewable portfolio standard implemented in Chile allied with the wind industry state in these countries indicate that Chile and Argentina will fulfill the 2020 wind power installed capacity predicted in the reference scenarios, while Brazil will reach the energy revolution scenario prediction. Important energy policy changes are required if the Chile and Argentina energy revolution scenarios wind power installed capacity are to become a reality in 2020. (author)

    Full Text Available This piece begins with a brief discussion of the concepts leading to the social right to health protection. Special emphasis is placed on the principle of social cohesion, which has influenced social health protection in European countries. Chile’s experience in this field from the 1990s to the present is described, as exemplified in three dimensions. In the first place, social security coverage is presented as a means to achieve universal (horizontal coverage. A discussion follows on vertical coverage, where the author identifies health problems for which insured persons have guaranteed rights of access to medical care. This section describes available emergency care, primary health care, and the special plan for Universal Access to Explicit Guarantees (Acceso Universal de Garantías Explícitas de salud, or AUGE. Thirdly, the discussion covers the funding sources supporting the Chilean health care system: Government subsidies, contributions to social security, and out-of-pocket disbursements for private care. Chile’s public health system has various special programs. One of them is catastrophic insurance, which covers 100% of the care needed for complex and very costly treatments. Older persons (over 65 have coverage for 100% of the cost of eyeglasses and hearing aids, and for 50% of the cost of home care. If life expectancy is an appropriate indicator of health system results, it is worth noting that Chile and the United States of America have both achieved a life expectancy of 77 years, even though Chile spends only 5.9% of its gross domestic product on health care, as compared to the 15% spent by the United States.

The result of geostatistical analysis is dependent on the sample density and other factors according to the georeferencing methodology used. Thus, this study aimed to compare two methods of georeferencing to characterize the spatial variability of RP and GM as well as the spatial correlation of these variables. Sampling grid of 60 points spaced 20 m was used. For RP measurements, an electronic penetrometer was used and to determine the GM, a Dutch auger (0.0-0.1 m depth was used. The samples were georeferenced using a GPS navigation receiver, Simple Point Positioning (SPP with navigation GPS receiver, and Semi-Kinematic Relative Positioning (SKRP with an L1 geodetic GPS receiver. The results indicated that the georeferencing conducted by PPS did not affect the characterization of spatial variability of RP or GM, neither the spatial structure relationship of these attributes.A caracterização da variabilidade espacial dos atributos do solo é indispensável para subsidiar práticas agrícolas de maneira sustentável. A utilização da geoestatística para caracterizar a variabilidade espacial desses atributos, como a resistência mecânica do solo à penetração (RP e a umidade gravimétrica do solo (UG, é, hoje, prática usual na agricultura de precisão. O resultado da análise geoestatística é dependente da densidade amostral e de outros fatores, como o método de georreferencimento utilizado. Desta forma, o presente trabalho teve como objetivo comparar dois métodos de georreferenciamento para a caracterização da variabilidade espacial da RP e da UG, bem como a correlação espacial dessas vari

Dos 146 primers escrutinados, 13 foram escolhidos para amplificação com cada um dos indivíduos das oito populações, gerando um total de 44 bandas polimórficas. Os resultados encontrados na Análise de Variância Molecular (AMOVA indicam que grande parte da variabilidade genética detectada se deve a diferenças entre indivíduos dentro de populações (75,47%. Na análise da estimativa dos percentuais de variabilidade genética entre pares de populações, foram observados maiores valores para os pares formados entre as cinco populações de cavalo Pantaneiro e a raça Árabe, enquanto os menores percentuais ocorreram entre Pantaneiro e Mangalarga Marchador. Maior índice de diversidade gênica foi observado na raça Pantaneiro (0,3396. No dendrograma gerado pelo método UPGMA, a partir da matriz de similaridade obtida pelo coeficiente de Jaccard, houve distinção entre as raças naturalizadas (Pantaneiro e Mangalarga Marchador e as exóticas (Árabe e PSI. Os resultados encontrados sugerem que o Pantaneiro apresenta maior variabilidade genética que os de outras raças e está estreitamente relacionado ao Mangalarga Marchador.

En Chile, la EEM no ha sido aplicada al manejo de estas pesquerías y la asesoría científica se ha desarrollado sobre la evaluación de estrategias de explotación utilizando modelos de evaluación mono-específicos. Para ambas especies se analizan los siguientes tópicos: i alternancia en la abundancia poblacional asociada a los pulsos de reclutamientos y capturas, ii variabilidad temporal en la fuerza del reclutamiento, iii estacionalidad del crecimiento cohorte y especie-específico, y iv relación ambiente-recurso. Los resultados evidencian que los tópicos analizados debieran ser considerados en la construcción de un modelo operativo y/o en la regla de cosecha, dado el carácter mixto de ambas pesquerías, su marcada alternancia y la influencia de las condiciones ambientales. Por lo tanto, se propone que el diseño e implementación de una EEM para sardina común y anchoveta, incluya los elementos señalados en un marco de evaluación multi-especifico y de manejo de carácter mixto.

Assim, o diagnóstico das tendências sazonais e mensais das chuvas é necessário, principalmente por se tratar de uma região com irregular distribuição espaço-temporal das chuvas. A variação da chuva mensal e sazonal na RSM foi analisada com base em séries climáticas de 45 anos (1960-2004. Aplicou-se na identificação de regiões com chuvas mensais homogêneas a análise de agrupamento (método de Ward. Com base na análise de agrupamento identificaram-se três grupos de estações com chuvas mensais homogêneas (G1, G2 e G3 e outras três estações que não foram agrupadas (NDg. As chuvas apresentaram gradiente espacial negativo na direção de G1 para G3 (nordeste-sudoeste, e totais entre os maiores nas estações do NDg (próximas ao litoral. O período chuvoso mostrou padrão similar, com maior comprimento nas estações do G1 e NDg e, menor nas estações do G3. As variabilidades sazonais e mensais das chuvas na RSM são condicionadas pelos Ciclones Tropicais, Sistemas Frontais, e a influência da Corrente Quente do Canal de Moçambique, enquanto as variabilidades espaciais são, principalmente, definidas pela Zona de Convergência Intertropical.

    A fertility study was carried out by the Chilean Association for Protection of the Family (APROFA) in metropolitan Chile in 1989 to update data from the most recent fertility study in 1974. A random and self-weighted sample of 600 women aged 15-44 in 32 urban communes of the metropolitan region were interviewed in November 1989. 55% were married or in stable consensual unions, 39.1% were single, and 5.9% were separated, divorced, or widowed. 24.1% had primary educations, 15.5% had some form of higher education, and .2% were illiterate. 64.2% of the women had children, of whom 63.8% had 1 or 2. Only 2.1% had 6 or more children. 46.2% felt that the ideal family size was 1-2 children and 30.7% that it was 3 children. 40.4% of women with children wanted another child and 59.6% did not. 25.1% of the sample had never had sexual relations, 7.3% had not had sexual relations in the 12 months prior to the interview, and the remaining 67.6% were sexually active. At the time of the survey 6.1% were pregnant and 11.1% had had a birth in the preceding 12 months. 28.3% of these pregnancies were considered unwanted, usually for economic reasons or because the family was considered complete. 55.6% of the sample reported using contraceptives. 48.6% used IUDs, 26.0% used oral contraceptives, 6.9% periodic abstinence methods, and 1.8% barrier methods. Only 7.5% of women aged 15-19 used contraception. Rates of use stabilized after age 25 at about 72%. 80.9% of women married or in union used a method, as did 20.2% of single and 59.3% of separated or divorced women. The data for the survey are still under analysis and all statistics are provisional.

    Brucellosis is a zoonosis caused by Brucella spp. It may be acquired by consuming unpasteurized dairy products. Brucellosis has a low incidence in Chile, thus, we have a scarce data. To report and to characterize the first series of clinical cases of adult patients diagnosed with brucellosis in Chile. We describe a series of 13 clinical cases in patients diagnosed between 2000 and 2016 in three different centers in the Metropolitan Region, Chile. A retrospective analysis was performed on clinical presentation, laboratory, antibiotic treatment, morbidity and mortality. The mean age was 50 years old. Eight cases had a record of consumption of unpasteurized dairy products. The most frequently reported complaints were fever. The most frequent focal point involved was the spine. Only one patient had a positive blood culture, while the diagnosis was made using serological techniques in the other part of the group. The most indicated antibiotic regimens were doxycycline-rifampicin and doxycycline-gentamicin. The hospital stay was 20 days approximately as an average. Clinical cure was achieved in all cases. Brucellosis is an infrequent zoonosis in Chile, and it produces a nonspecific clinical picture, so it is necessary to have high suspicion to make the diagnosis based in the antecedent of consumption of unpasteurized dairy or raw meat.

    2014-01-01

    Health research is considered an essential element for the improvement of population health and it has been recommended that a share of the national health budget should be allocated to develop this field. Chile has undertaken efforts in the last decades in order to improve the governmental structure created to promote the development of health research, which has increased human resources and funding opportunities. On the other hand, the sustained economic growth of Chile in the last decades suggests that the health expenditure will maintain its increasing trend in the following years. This additional funding could be used to improve coverage of current activities performed in the health system, but also to address the incorporation of new strategies. More recently, health technology assessment (HTA) has been proposed as a process to support decisions about allocation of resources based on scientific evidence. This paper examines the relationship between the development of health research and the HTA process. First, it presents a brief diagnosis of the situation of health research in Chile. Second, it reviews the conceptual basis and the methods that account for the relationship between a HTA process and the development of health research. In particular, it emphasizes the relevance of identifying information gaps where funding additional research can be considered a good use of public resources. Finally, it discusses the challenges and possible courses of action that Chile could take in order to guarantee the continuous improvement of an articulated structure for health research and HTA.

    Chile has experienced several serious energy supply incidents over the last decade, including major droughts, a sustained gas supply cut from Argentina (since 2004), and a major earthquake in early 2010 which affected electricity networks and refineries, and caused several black-outs. Due to Chile's unique and sinuous geography - it runs 4 300 kilometres from North to South and only 175 kms from East to West- the country's energy markets are regionally disjointed, particularly as the regional gas and electricity grids are not connected. In the arid North, energy demand is dominated by the mining industry, and operates based on a separate thermal-based Sistema Interconectado Norte Grande (SING) electricity grid. The more densely-populated central region (including Santiago) operates on the more hydro-dependent Sistema Interconectado Central (SIC) electricity grid. The southernmost, hydro-rich regions of the country are not connected to the rest of Chile in terms of electricity and gas. The following report is based on an IEA Emergency Response Assessment carried out in 2010 and 2011 which looked specifically at Chile's capacity to respond to short-term emergencies in oil, gas and electricity.

    In February and March 2010 we conducted preliminary exploration for hydrothermal plume signals along the East Chile Rise where it intersects the continental margin at the Chile Triple Junction (CTJ). This work was conducted as one component of our larger NOAA-OE funded INSPIRE project (Investigation of South Pacific Reducing Environments) aboard RV Melville cruise MV 1003 (PI: Andrew Thurber, Scripps) with all shiptime funded through an award of the State of California to Andrew Thurber and his co-PI's. Additional support came from the Census of Marine Life (ChEss and CoMarge projects). At sea, we conducted a series of CTD-rosette and ABE autonomous underwater vehicle operations to prospect for and determine the nature of any seafloor venting at, or adjacent to, the point where the the East Chile Rise subducts beneath the continental margin. Evidence from in situ sensing (optical backscatter, Eh) and water column analyses of dissolved CH4, δ3He and TDFe/TDMn concentrations document the presence of two discrete sites of venting, one right at the triple junction and the other a further 10km along axis, north of the Triple Junction, but still within the southernmost segment of the East Chile Rise. From an intercomparison of the abundance of different chemical signals we can intercompare likely characteristics of these differet source sites and also differentiate between them and the high methane concentrations released from cold seep sites further north along the Chile Margin, both with the CTJ region and also at the Concepcion Methane Seep Area (CMSA). This multi-disciplinary and international collaboration - involving scientists from Chile, the USA, Europe and Japan - can serve as an excellent and exciting launchpoint for wide-ranging future investigations of the Chile Triple Junction area - the only place on Earth where an oceanic spreading center is being actively subducted beneath a continent and also the only place on Earth where all known forms of deep

    Full Text Available El vínculo que se constituye entre profesor y estudiante, que involucra afectos y emociones, es fundamental en el proceso educativo y no está ajeno a elementos sociales, históricos y estructurales que le rodean. Considerando aquello, el propósito de esta investigación es comprender los discursos que los docentes construyen en torno a las condicionantes estructurales del vínculo profesor-estudiante. Para el logro de este objetivo, nos posicionamos desde el enfoque del análisis crítico de discurso y utilizamos dos técnicas para la producción de datos, el grupo focal y la entrevista episódica. Los participantes del estudio fueron docentes pertenecientes a cuatro escuelas secundarias de Santiago de Chile y para el análisis de los datos seguimos el modelo tridimensional propuesto por Norman FAIRCLOUGH. Los principales resultados dan cuenta que en los discursos docentes se logra identificar condicionantes estructurales del vínculo, tales como la institución escolar jerárquica, el modelo educativo agobiante y la sociedad como una estructura que aplasta. No obstante, también encontramos contradicciones y variabilidad discursiva en el posicionamiento del docente que podrían deberse al contexto actual de reformas y movilizaciones sociales por la educación.

  9. The socioeconomic impact of drug-related crimes in Chile.

    2012-11-01

    Illegal drug use and trafficking are closely connected to crime. This article estimates the socioeconomic impact of this connection in Chile. Goldstein's tripartite model was applied quantifying drug-crime connections and then using those estimates to measure the socioeconomic impact of drug-related crimes. This was estimated in terms of both the monetary cost of law enforcement, and lost productivity due to incarceration. This socioeconomic impact can be divided into: (a) the direct costs arising from infractions to Chile's Drug Law, and the indirect costs originated by crimes linked only partially to drug consumption and trafficking; (b) is measured in productivity losses, as well as in costs to the three branches of Chile's criminal justice system (police, judiciary, and prisons); and (c) is attributed to the three illicit drugs most prevalent in Chile: cannabis, cocaine hydrochloride (CH) and cocaine base paste (CBP). The socioeconomic impact of Chile's drug-crime relationship in 2006 is estimated to be USD 268 million. Out of this amount, 36% is spent on national Drug Law enforcement, and the remaining 64% comes from the connection of drug use and trafficking with non-Drug-Law-related crimes. The police bear the largest share of drug enforcement costs (32%), followed by penitentiaries (25%). Productivity losses due to incarceration for drug-related crimes represent 29% of the total impact. 53% of the costs are attributable to CBP, 29% to CH, and the remaining 18% to cannabis. The impact of CBP is greater when indirect costs are taken into account, although direct costs are primarily associated with CH. The majority of costs is attributed to the trafficking and consumption of CBP, a drug with a relatively low prevalence. Based on the results, this study suggests reviewing drug enforcement policies to differentiate them according to the social and individual harm caused by each drug. Copyright © 2012 Elsevier B.V.

    Full Text Available Este artículo presenta una visión general de la historia del jazz en Chile que destaca la función social de esta música y el cambio que tuvo a través del tiempo. Estos cambios se relacionaron con diferentes valoraciones de la práctica jazzística local. En un principio el jazz fue música popular masiva. Posteriormente fue valorado estéticamente por un segmento de élite, quienes eran profesionales en áreas no musicales y en muchos casos eran instrumentistas aficionados. En una tercera etapa, músicos profesionales asumieron la práctica del jazz como una plataforma para fusionar el lenguaje jazzístico con recursos tomados de la música tradicional chilena. Este tránsito del jazz en Chile está cruzado por factores socioeconómicos y estéticos, que se analizan en el trabajo.The article presents an overview of the history of jazz in Chile on the basis of the social function of jazz and the changes it has underwent over the years in terms of the valúes it has represented for Chilean society. Initially jazz was considered as mass popular music. Afterwards it was valued in aesthetic terms by a group belonging to the élite of Chilean society. Many of them belonged to non-music professions and in some cases were amateur musicians. Most recently professional musicians took up jazz as the basis for combining the jazz style with elements belonging to traditional music of Chile. This process in Chile is also influenced by social, economic and aesthetic aspects which are explored in this article.

Los resultados obtenidos indicaron a nivel reproductivo, que el desarrollo gonadal de la población es asincrónico, encontrándose ejemplares en diferentes etapas de maduración durante el año. Los individuos maduros se estratificaron entre 5 y 13 m de profundidad, y gran parte del año formaron agregaciones a 5 m de profundidad. Se determinaron períodos de mayor madurez en julio-agosto, y en noviembre-enero, manifestándose las agregaciones más importantes al final de ellos. Una relación se observó entre meses de mayor madurez y registro de agregaciones, con aquellos de mayor variación intradiaria de temperatura. A nivel poblacional los resultados permitieron estimar una población de 2,3*10(6 ejemplares, donde el 39% se encontró sobre la talla mínima legal (TML = 55 mm. Los parámetros de crecimiento mostraron crecimiento relativamente lento, que podría estar influenciado por la alta variabilidad que presenta la temperatura de fondo en este sector. Mientras que su talla crítica, y la talla de primera madurez sexual poblacional, resultaron ser mayores a la TML. Se determinó la necesidad de revisar la normativa pesquera actual de esta especie, y se demostró la efectividad de las reservas marinas propiciadas por el Estado en la conservación de los recursos marinos.Reproductive and population parameters of Thais chocolata that would contribute to the validation of the current extraction standards were obtained by performing a study in the protected area of La Rinconada Marine Reserve, Antofagasta, Chile, from December 2008 to January 2010.

    Full Text Available Approximately 85% of the water consumed in Chile is destined to agricultural irrigation and is managed by the users themselves. This study analyzed the price that irrigation water users pay to their Water User Associations (WUAs to which they belong and the relationship of this price to the professional level and performance of the WUAs. The study included 24 WUAs: 10 River Administration Boards (JV and 14 Irrigation Canal Associations (AC. The annual operational budget of each WUA, the price paid by users and the management capacities of the board of directors of each WUA were compared. The study also determined the relative value of user payments to WUAs as a proportion of total production costs of the main crops in each zone. The variability of user fees per irrigated hectare decreases when the irrigation area of the WUA is more than 10 000 ha, though this was not observed in JVs. The presence of technical-professional staff directly affects the development and growth of the WUAs. As well, the WUAs with a greater level of capacity development (NDC have more board members with a higher education level and have lower rates of unpaid user fees. The price that users pay to the WUA by irrigated hectare represents less than 4.0% of the average total production cost of the main crops in the study area. Finally, no correlation was found between the prices that users pay and the average profitability of the main crops, or between price and the geographical location of the WUAs.Aproximadamente, el 85% del agua consumida en Chile es destinada al riego agrícola, siendo administrada por los propios usuarios.

    Full Text Available A nivel demográfico, los resultados clásicos de los modelos matriciales separan a las especies de tiempo generacional corto de las especies de tiempo generacional largo en cuanto a la importancia de la supervivencia adulta para la dinámica poblacional. Específicamente, la supervivencia adulta no debería contribuir de manera importante en la tasa de cambio poblacional de especies de tiempo generacional corto. Sin embargo, Yoccoz et al. (1998, Research Population Ecology 40: 107-121 propusieron que la supervivencia adulta sería el parámetro demográfico más importante para determinar la tasa de cambio poblacional en pequeños roedores cuando se toma en consideración una escala de tiempo mensual. Con el fin de poner a prueba esta hipótesis en este trabajo, utilizamos cinco años de datos de captura-marcaje-recaptura para estimar la supervivencia y la maduración de las hembras del lauchón orejudo, Phyllotis darwini, en una localidad de Chile central. El análisis mostró que las probabilidades de supervivencia disminuían con el promedio anual de la cantidad de lluvia y que las probabilidades de maduración disminuían con la densidad poblacional. Basados en las probabilidades de supervivencia y maduración, construimos un modelo matricial estacional para medir la importancia relativa de cada parámetro demográfico en el ciclo de vida de la especie a través de un análisis de perturbación. A fin de reflejar la variabilidad estacional del ambiente, dos estaciones fueron incorporadas en el modelo matricial: una estación de lluvia de cinco meses y una estación seca. Se observó que la supervivencia adulta era en efecto el parámetro demográfico con la elasticidad más fuerte. Por lo tanto, estos resultados apoyan la hipótesis de Yoccoz et al. (1998Classic results of matrix models predict that, in species with a long generation time, adult survival should be the demographic parameter driving population dynamics whereas, in species

    Full Text Available El Pacífico suroriental es una de las áreas más productivas del planeta debido a su intensa dinámica de circulación oceánica cuya manifestación más importante, desde el punto de vista oceanográfico y biológico, la constituye los afloramientos costeros que generan una elevada producción primaria y secundaria que sustentan importantes poblaciones de peces que son la base de la economía pesquera de la región. Sin embargo, en esta región la normalidad es la variabilidad, que responde a patrones reguladores de macroescala como los estacionales, interanuales, periódicos y seculares, como procesos de corto, mediano, largo y muy largo plazo. En estos escenarios ambientales aparecen como factores o manifestaciones de variabilidad el ENOS (El Nino Oscilación del Sur, la ODP (Oscilación Decadal del Pacífico y la VSP (Variabilidad Secular del Pacífico como los más conspicuos. Tanto la temporalidad como los factores de variabilidad afectan el ecosistema y, dentro de éste a los recursos y sus pesquerías. Estos cambios están referidos al tiempo, espacio, poblaciones y pesquerías. Es decir, los procesos de dinámica poblacional de los recursos, como reclutamiento, crecimiento y mortalidad natural y por pesca, están siendo afectados permanentemente, a intensidades y frecuencias escalares diferentes. Esta situación estaría induciendo respuestas dinámicas de las poblaciones que a su vez generan estados poblacionales frente a cada uno de los momentos o escenarios ambientales imperantes. El trabajo presenta un análisis de los patrones normativos y factores de variabilidad usando variables ambientales, biológicas y pesqueras y se identifican escenarios que explicarían los cambios de las poblaciones y sus pesquerías facilitando la adopción de medidas de gestión aplicables a cada estado ambiental. Esto permitirá la planificación de las pesquerías para prevenir colapsos socioeconómicos y financieros, así como obtener los m

Objetivos: Determinar los factores asociados a la esperanza de vida en Chile. Diseño: Análisis econométrico. Lugar: Chile. Intervenciones: Aplicación del modelo de regresión múltiple con series temporales para el análisis de la esperanza de vida en Chile. Se utilizó datos de naturaleza agregada del Instituto Nacional de Estadística (INE y el Banco Central de Chile para el período comprendido entre 1988 y 2008. Se utilizó como variable dependiente la esperanza de vida en años y, como variables explicativas, el PIB per cápita, número de médicos, número de enfermeras y gasto público en salud. Principales medidas de resultados: Factores asociados a la esperanza de vida. Resultados: Luego del análisis, los resultados han puesto de manifiesto que el ingreso per cápita, el número de médicos, número de enfermeras y el gasto en salud resultaron ser estadísticamente significativos, es decir, tienen un efecto positivo sobre la esperanza de vida de las personas. Conclusiones: A la luz de los resultados podría argumentarse lo beneficioso que puede resultar en términos cuantitativos un aumento del PIB per cápita a la hora de conseguir una mayor esperanza de vida de las personas. Igualmente, los resultados sugieren el efecto positivo que produce un incremento del número de personal médico en el país dado, pues esta variable ha permitido satisfacer la demanda sanitaria cada vez más creciente de la población. El aumento del presupuesto social en salud ha sido una variable que ha tenido un resultado positivo a la hora de valorar su efecto en la mejora de las condiciones de vida en Chile.

Foram utilizados três tipos de marcador de DNA: RAPD, AFLP e microssatélites. A análise dos resultados consistiu na descrição do padrão de bandas, cálculo de índices de similaridade (Nei & Li; 1979 e análise de coordenadas principais (PCoA, para cada tipo de marcador. Para os locos de microssatélites foram calculados também: heterozigozidade, índices de diversidade (DI, de Weir e coeficientes de diferenciação genética (G ST. A variabilidade genética mostrou-se mais concentrada dentro de regiões do que entre regiões (G ST = 0,07. A heterozigozidade média foi de 56%.

Se evaluaron 18 descriptores morfo-agronómicos asociados con características de la planta, vaina y semilla. Mediante el análisis de las faseolinas utilizando SDS-PAGE se encontraron patrones de bandas de origen andino (T, C y H1 y mesoamericano [S, Sb, CH y H(S+I]. También se evaluaron ocho sistemas isoenzimáticos polimórficos. En el germoplasma de habichuela hay importante contribución del acervo mesoamericano y las accesiones en algunos centros secundarios de domesticación tuvieron origen y procesos de dispersión diferentes de los del fríjol común en tales zonas. La mayor variabilidad morfológica y el mayor número de accesiones con características deseables para el mercado fresco se encontró en el grupo mesoamericano. Se detectó mayor número de genotipos híbridos entre acervos cuando se utilizaron simultáneamente los tres descriptores, lo cual indica una estructura genética compleja que podría deberse al efecto de los factores ambientales propios de la zona templada sobre sus patrones reproductivos. La diversidad total medida con los tres descriptores fue similar a la registrada en fríjol común. Sin embargo, la estructura poblacional encontrada por otros autores en el fríjol común es diferente de la observada en este estudio.

    Full Text Available The influence of relief forms has been studied by several authors and explains the variability in the soil attributes of a landscape. Soil physical attributes depend on relief forms, and their assessment is important in mechanized agricultural systems, such as of sugarcane. This study aimed to characterize the spatial variability in the physical soil attributes and their relationship to the hillslope curvatures in an Alfisol developed from sandstone and growing sugarcane. Grids of 100 x 100 m were delimited in a convex and a concave area. The grids had a regular spacing of 10 x 10 m, and the crossing points of this spacing determined a total of 121 georeferenced sampling points. Samples were collected to determine the physical attributes related to soil aggregates, porosity, bulk density, resistance to penetration and moisture within the 0-0.2 and 0.2-0.4 m depth. Statistical analyses, geostatistics and Student's t-tests were performed with the means of the areas. All attributes, except aggregates > 2 mm in the 0-0.2 m depth and macroporosity at both depths, showed significant differences between the hillslope curvatures. The convex area showed the highest values of the mean weighted diameter, mean geometric diameter, aggregates > 2 mm, 1-2 mm aggregates, total porosity and moisture and lower values of bulk density and resistance to penetration in both depth compared to the concave area. The number of soil attributes with greater spatial variability was higher in the concave area.A influência das formas do relevo tem sido estudada por diversos autores e explica a variabilidade dos atributos do solo na paisagem.

    Full Text Available O Sorghum bicolor (L. Moech é uma importante forrageira de alta produção, que cresce no cenário brasileiro ainda de forma lenta em substituição ao cultivo de milho safrinha. A cultura do sorgo seria alternativa no período da seca na produção de silagem para o período das águas; contudo, o crescimento e desenvolvimento das plantas pode ser influenciado por alterações nos atributos do solo, como textura, porosidade e estrutura do solo. O objetivo deste trabalho foi analisar e caracterizar a dependência e variabilidade espacial entre atributos do solo e a cultura do sorgo forrageiro, em um Planossolo Hidromórfico no ecótono Cerrado-Pantanal. Para tanto, estimaram-se a produtividade de matérias verde e seca de forragem (MVF e MSF de sorgo forrageiro e os atributos do solo, como macroporosidade (Ma, microporosidade (Mi, porosidade total (Pt, diâmetro médio geométrico, diâmetro médio ponderado, índice de estabilidade de agregados (IEA e teor de carbono orgânico total do solo (COT, em duas profundidades: 1 (0,00-0,10 m e 2 (0,10-0,20 m. Em relação à malha geoestatística, foram realizadas 50 coletas de atributos de planta e solo em 40 ha. Isso possibilitou detectar a elevada variabilidade espacial dos atributos de planta (MVF e MSF e também os atributos do solo que mais variaram espacialmente. Com relação às variáveis que apresentaram dependência espacial, o coeficiente de determinação (r2 decresceu na seguinte ordem: IEA1, silte2, Ma1, Pt1, areia2, silte1, MSF, argila1, MVF e IEA2. Com isso, verificou-se que IEA1 apresentou o melhor ajuste semivariográfico (r2 = 0,926, com alcance de 677,0 m, e o avaliador da dependência espacial (50,6 % moderado. O silte1, porém, evidenciou o menor alcance (111,0 m e, assim, recomenda-se que em estudos posteriores o alcance mínimo a ser adotado, para esse tipo de avaliação, não deve ser inferior a esse valor em Planossolo Hidromórfico sob preparo convencional.

    Full Text Available Three sandy beaches located in southern Chile (Gaviotas, Guabún and Mar Brava; ca. 42º S were studied during the summer of 2000 to analyse the patterns in abundance and biomass of the meiofauna along a gradient of morphodynamic beach types. Sediment samples were collected with metallic cylinders (23 cm² cross sectional area, 120 cm long at ten equally spaced tidal levels along six transects separated between 5 and 10 m and extending from above the drift line down to the low tide level. Porosity, shear strength, water content, penetrability and grain size of the substrate were measured in each sampling level. The meiofauna was primarily represented by Nematoda and Copepoda Harpacticoidea. The highest average density and biomass per unit of area were found at the reflective beach of Gaviotas (6,172 ind 10 cm-2 and 2.38 g m-2, ash free dry weight as compared with the intermediate beach of Guabún (3,390 ind 10 cm-2 and 1.70 g m-2 and the dissipative beach of Mar Brava (3,667 ind 10 cm-2 and 0.86 g m-2. Total abundance and biomass of the meiofauna per linear meter of beach (i.e., total meiofauna in an intertidal across-shore transect 1 m wide were higher at Mar Brava (506 x 10(6 ind m-1 and 119.4 g m-1, as compared with Gaviotas (271 x 10(6 ind m-1 and 101.7 g m-1 and Guabún (143 x 10(6 ind m-1 and 73.9 g m-1. Therefore, these last results show a trend of increasing intertidal meiofaunal abundances and biomass towards the dissipative stage of the beach gradient analyzed. The highest meiofaunal densities and biomass occurred at the upper and mid shore levels of each beach. Lower across-shore variability in density and biomass were found at the dissipative beach. Results of a Monte Carlo permutation test showed that water content, penetrability and grain size were the best predictor variables of meiofaunal density. Body sizes of nematodes, copepods, turbellarians, halacarids and ostracods were correlated with sediment characteristics. In general

    Full text: A three years isotope data on precipitation collected in northern Chile show a very distinct pattern, with depleted δ 18 and -150/00 observed at high altitude stations, compared to δ 18 0 values ranging between - 10 and -6/00 measured at the lower altitude areas. The depleted δ 0 values observed in the high altitude area, the Altiplano, are related to different processes that affect the air masses as moved from the Atlantic, crossed the Amazon Basin (continental effect), ascend the Andes (altitude effect) and precipitated (convective effect) in the Altiplano. It is postulated that a second source of moisture, associated to air masses from the Pacific, explained the enriched isotopic values observed in the lower altitude areas. Similar isotopic pattern, documented in springs and groundwater, indicates that the rain data presented in this paper is an accurate representation of the long term behavior of the isotopic composition of the rain in northern Chile

    Full Text Available From colonial times well into the twentieth century (and, unfortunately, even beyond the man/land relationship in Latin America has been markedly unjust. Small numbers of families have owned large tracts of the best land, while large numbers of poor families have struggled with tiny plots of marginal land or labored on the estates of the rich. Chile was no exception to this pattern. Thus, its experiment with land reform in the 1960s and 1970s, the setback of reform under the military in the 1970s and 1980s, and the resumption of reform under democrats in the 1990s, may provide lessons for the rest of Latin America. Is a preferential option for the rural poor still possible in a neoliberal economic system? In Chile, the answer is a qualified “yes”

    Breastfeeding practices have greatly diminished in all industrialized countries in the past 30 years; only now breastfeeding is enjoying a revival, especially among better educated people, as data gathered in Sweden and in the U.S. show. In Chile, as in most underdeveloped countries, the practice of breastfeeding began declining in urban, then in rural areas, reaching the largest decline in 1930. Modernization and all the factors connected with it, and especially urbanization, are accountable for this change. To encourage breastfeeding in Chile several recommendations are possible, among which is the education of parents on the advantages of breastfeeding. Mass media and all communication channels should be used; 2) better alimentation, when necessary at government expenses, for pregnant and nursing mothers; 3) legislation regulating the advertisement and distribution of infant formulas; 4) information on the possible effects of oral contraception on lactation; and 5) new social legislation protecting pregnant and nursing mothers.

    1977-08-01

    Chile has an area of 740,760 square kilometers. The capital is Santiago. The country is 4,183 km. long and ranges from 22.5 to about 354 km. in width. Its chief topographic features para]lei each other - the Coastal Range, Andes Mountains and Central Valley. The Coastal Range rises to 2,130 meters in the north, but averages from 610 to 700 meters high generally. The range plunges into the Pacific Ocean far south of Valparaiso and reappears in the southern archipelagic islands. The Andes extend along nearly the entire length of Chile and contain 100 volcanoes. Andean peaks range mostly from 3,000 to 6,700 meters in elevation. In southern Chile the Andes are lower, and contain about a dozen major lakes. The mountains disappear in Chilean Patagonia, but reappear at Cape Horn. The Central Valley lies between the Coastal Range and the Andes, being best defined in the midland region as a 64 to 72 km sloping plain. It is the Chilean heartland with three-quarters of the country's population. Salt basins are found over much of northern Chile in the very arid desert, while the region south of the Gulf of Reloncavi consists of unpopulated islands, fjords, channels and heavily forested mountains. The Strait of Magellan, the Tierra del Fuego archipelago and a flat grassland area make up the extreme southern end of the country. Much of Chile is subject to flash floods, earthquakes, volcanic eruptions, landslides and avalanches. In September 1976 the Comision Chilena de Energia Nuclear (CCEN) was given exclusive rights to negotiate contracts with private companies for the exploration, development and mining of uranium and other radioactive minerals. The new law provides the CCEN with considerable flexibility in the terms of the contracts. Pre-964 owners of uranium deposits may reach agreements with foreign companies to mine the uranium, but since 1964 all uranium has belonged to the state. Uranium produced in the country can only be exported after Chile's needs have been met. The

    Male attitudes toward family planning education were assessed through a study of 720 men in Santiago and 240 men in a nearby rural area of Chile. Interviews were conducted by male students at the University of Chile School of Public Health. A large majority of the men were using or planned to use contraception in the future. There was a near consensus that adults should be informed regarding family planning. More than a majority of the respondents favored provision of contraceptive information for unmarried women, but most did not approve of premarital sexual activity for females. Most respondents favored the teaching of sex education in schools "according to the age of the children." Younger and higher class males tended to hold the most liberal attitudes.

    INTRODUCTION: Epidemiological studies of the 1957 influenza pandemic are scarce, particularly from lower income settings. METHODS: We analyzed the spatial-temporal mortality patterns of the 1957 influenza pandemic in Chile including detailed age-specific mortality data from a large city...... with high baseline mortality (R2=41.8%; P=0.02), but not with latitude (P>0.7). Excess mortality rates increased sharply with age. Transmissibility declined from R=1.4-2.1 to R=1.2-1.4 between the two pandemic waves. CONCLUSIONS: The estimated A/H2N2 mortality burden in Chile is the highest on record...... for this pandemic - about 3-5 times as severe as that experienced in wealthier nations. The global impact of this pandemic may be substantially underestimated from previous studies based on high-income countries....

    2015-09-01

    In spite of the high prevalence of mental health disorders in Chile, there is a significant financing deficit in this area when compared to the world's average. The financing for mental health has not increased in accordance with the objectives proposed in the 2000 Chilean National Mental Health and Psychiatry Plan, and only three of the six mental health priorities proposed by this plan have secure financial coverage. The National Health Strategy for the Fulfilment of Health Objectives for the decade 2011-2020 acknowledges that mental disorders worsen the quality of life, increase the risk of physical illness, and have a substantial economic cost for the country. Thus, this article focuses on the importance of investing in mental health, the cost of not doing so, and the need for local mental health research. The article discusses how the United States is trying to eliminate the financial discrimination suffered by patients with mental health disorders, and concludes with public policy recommendations for Chile.

    Seabird eggs are proposed as biomonitors of chemical contamination in Chile. - Seabird eggs were used as bioindicators of chemical contamination in Chile. Brown-hooded Gull (Larus maculipennis), Kelp Gull (Larus dominicanus), Trudeau's Tern (Sterna trudeaui), Neotropic Cormorant (Phalacrocorax brasilianus), and Pink-footed Shearwater (Puffinus creatopus) eggs were sampled at different breeding sites during the 1990s. Mercury and organochlorines (PCBs, DDT, HCB, HCH, and PCP) were quantified to reveal the interspecific differences, spatial and temporal trends in contamination levels. Trudeau's Tern displayed the highest levels of mercury (486 ng g{sup -1} wet weight). The highest {sigma}DDT concentrations were measured in Brown-hooded Gulls (726 ng g{sup -1}). PCB levels were similar among the species (102-236 ng g{sup -1}), but the composition of the PCB mixture was different in Pink-footed Shearwaters. With the exception of the Brown-hooded Gull, all species studied presented similar and low levels of organochlorines ({sigma}OHa). Residues of PCB and related compounds were not detected in any of the seabird eggs analyzed in Chile. Geographical variation was low, although levels of industrial chemicals were slightly higher in eggs from Concepcion Bay, and agricultural chemicals in eggs from Valdivia. Also interannual variation was low, but some evidence was found of decreasing levels in gull eggs throughout the time of the study. The causes of the low levels and small variability in space and time of environmental chemicals in Chilean seabirds are discussed. We propose the use of seabirds in future monitoring of the development of chemical contamination in Chile.

    This study analysed factors associated with unintended pregnancy among adolescent and young adult women in Santiago, Chile. Three variations of a behavioural model were developed. Logistic regression showed that the effect of sex education on unintended pregnancy works through the use of contraception. Other significant effects were found for variables reflecting socioeconomic status and a woman's acceptance of her sexuality. The results also suggested that labelling affects measurement of 'unintended' pregnancy.

    Seabird eggs are proposed as biomonitors of chemical contamination in Chile. - Seabird eggs were used as bioindicators of chemical contamination in Chile. Brown-hooded Gull (Larus maculipennis), Kelp Gull (Larus dominicanus), Trudeau's Tern (Sterna trudeaui), Neotropic Cormorant (Phalacrocorax brasilianus), and Pink-footed Shearwater (Puffinus creatopus) eggs were sampled at different breeding sites during the 1990s. Mercury and organochlorines (PCBs, DDT, HCB, HCH, and PCP) were quantified to reveal the interspecific differences, spatial and temporal trends in contamination levels. Trudeau's Tern displayed the highest levels of mercury (486 ng g -1 wet weight). The highest ΣDDT concentrations were measured in Brown-hooded Gulls (726 ng g -1 ). PCB levels were similar among the species (102-236 ng g -1 ), but the composition of the PCB mixture was different in Pink-footed Shearwaters. With the exception of the Brown-hooded Gull, all species studied presented similar and low levels of organochlorines (ΣOHa). Residues of PCB and related compounds were not detected in any of the seabird eggs analyzed in Chile. Geographical variation was low, although levels of industrial chemicals were slightly higher in eggs from Concepcion Bay, and agricultural chemicals in eggs from Valdivia. Also interannual variation was low, but some evidence was found of decreasing levels in gull eggs throughout the time of the study. The causes of the low levels and small variability in space and time of environmental chemicals in Chilean seabirds are discussed.

  18. Climate change and energy policy in Chile: Up in smoke?

    International Nuclear Information System (INIS)

    2013-01-01

    This paper provides an ex-post assessment of the climate and energy policy developments in Chile emerging from a neoliberal economic model, during the period 1971–2007. First, correlation and regression analyses were performed to analyse historical CO 2 emissions as a product of demographic, economic and energy-wide drivers. Then I estimate indicators related to CO 2 emissions, energy use and economic activity. In the light of empirical results, I identify policy instruments and structural issues. Finally, I present a comparative analysis of Chile and other Latin American countries. Statistical tests show that variability of CO 2 emissions is explained mostly by GDP per capita (‘affluence’) than any other tested variable. Indicators show that the diversification and decarbonisation of the energy mix has been a major policy challenge. With two notable exceptions (hydro and natural gas), the CO 2 intensity of the energy supply mix suggests no effective policies, while energy security crises triggered negative carbon effects and increased prices. No clear policies to promote energy efficiency can be identified until 2005. Explicit policy instruments to promote renewable energy are only recognised after 2004. The results strongly suggest that Chile lacked of policies to effectively decarbonise its energy–economy system. - Highlight: ► The first paper that quantitatively assesses key drivers of CO 2 emissions in Chile. ► It examines energy and climate policy development during the period 1971–2007. ► GDP per capita (‘affluence’) is the main determinant of CO 2 emissions. ► Diversification and decarbonisation of energy mix has been a major policy challenge. ► Policy approach under analysed period not suited for a low-carbon economy.

    This paper seeks to highlight the problems of gaps in health infrastructure in Chile, and to analyze the mechanisms by which it is provided. In Chile this is done in two ways: the first is through competitive bidding or sector-wide modality. The second way is through hospital concessions. Both mechanisms have had difficulties in recent years, which are reported. Finally, we propose ways to improve the provision of health infrastructure in Chile.

  10. Teenage sexuality and rights in Chile: from denial to punishment.

    2009-11-01

    While Chile sees itself as a country that has fully restored human rights since its return to democratic rule in 1990, the rights of teenagers to comprehensive sexuality education are still not being met. This paper reviews the recent history of sexuality education in Chile and related legislation, policies and programmes. It also reports a 2008 review of the bylaws of 189 randomly selected Chilean schools, which found that although such bylaws are mandatory, the absence of bylaws to prevent discrimination on grounds of pregnancy, HIV and sexuality was common. In relation to how sexual behaviour and discipline were addressed, bylaws that were non-compliant with the law were very common. Opposition to sexuality education in schools in Chile is predicated on the denial of teenage sexuality, and many schools punish sexual behaviour where transgression is perceived to have taken place. While the wider Chilean society has been moving towards greater recognition of individual autonomy and sexual diversity, this cultural shift has yet to be reflected in the government's political agenda, in spite of good intentions. Given this state of affairs, the Chilean polity needs to recognise its youth as having human rights, or will continue to fail in its commitment to them.

    Teenage fecundity rates are an indicator of epidemiological discrimination in developing countries. To study fertility rates of girls under 14 years of age in Chile from 1993 to 2003. Information of children born alive from mothers aged 10 to 15 years, was obtained from the Chilean National Institute of Statistics. Age segmented population data was obtained from the Ministry of Health. Trends were analyzed by regions and single ages. The rates in communities of the Metropolitan Region were compared. Between 1993 and 2003, there was an increasing trend in fecundity rates, ratios and crude numbers. These rates duplicate from 14 to 15 years of age. In the Metropolitan Region, the fecundity ratios of communities with lower economical incomes is seven times greater than those with higher incomes. During 2003, the fecundity rates in Chile were 100 and 10 higher than those of Holland and Sweden in 1981. In developing countries with very low infant mortality rates such as Chile, the high fecundity rates of young girls is an indicator of a deficient human and social development. Sexual Education and Health Services for adolescents are essential to prevent this public health problem.

    Mortality rates for cervical cancer (CC) in Chile are higher than those of developed countries and it has an unequal socioeconomic distribution. The recognition of human papilloma virus (HPV) as the causal agent of cervical cancer in the early 80's changed the prevention paradigms. Current goals are to prevent HPV infection by vaccination before the onset of sexual activity and to detect HPV infection in women older than 30 years. This article reviews CC prevention and early detection methods, discusses relevant evidence to support a change in Chile and presents an innovation proposal. A strategy of primary screening based on HPV detection followed by triage of HPV-positive women by colposcopy in primary care or by cytological or molecular reflex testing is proposed. Due to the existence in Chile of a well-organized nationwide CC prevention program, the replacement of a low-sensitivity screening test such as the Papanicolau test with a highly sensitive one such as HPV detection, could quickly improve the effectiveness of the program. The program also has a network of personnel qualified to conduct naked-eye inspections of the cervix, who could easily be trained to perform triage colposcopy. The incorporation of new prevention strategies could reduce the deaths of Chilean women and correct inequities.

    Full Text Available A series of already published and unpublished seroepidemiological surveys for toxoplasmosis, carried out in Chile in 1982-1994, is reviewed, expanded and analyzed. The surveys included 76,317 apparently healthy individuals of different ages (0.57% of the country's total population, from 309 urban and rural-periurban localities. Urban groups were integrated by blood donors, delivering mothers and middle grade schoolchildren, while rural-periurban individuals corresponded to unselected family groups. Blood samples were collected in filter paper. The presence of antibodies to Toxoplasma gondii was determined by the indirect hemagglutination test (IHAT, titers > 16 were considered positive. The test resulted positive in 28,124 (36.9% of the surveyed people. Two hundred and six (0.3% individuals presented IHAT titers > 1000, probably corresponding to acute or reactivated infections. A progressive increase of positive IHAT from northern to southern regions of the country was noted, phenomenom probably related to geographical conditions and to a higher production and consumption of different types of meat in the latter regions. It is postulated that ingestion of T. gondii cysts by humans is epidemiologically as important as ingestion of oocysts. The results presented stress the epidemiological importance of toxoplasmosis in humans, and warn about eventual implications in immunocompromised patients and in transplacental transmission, organ transplants and transfusions.En este trabajo se revisa, se amplía y se analiza en conjunto una serie de encuestas seroepidemiológicas sobre toxoplasmosis efectuadas en Chile entre 1982 y 1994, utilizando la reacción de hemaglutinación indirecta (RHAI.

    Cuba and Chile have the lower infant mortality rates of Latin America. Infant mortality rate in Cuba is similar to that of developed countries. Chilean infant mortality rate is slightly higher than that of Cuba. To investigate if the lower infant mortality rate in Cuba, compared to Chile, could be explained by eugenic abortion, considering that abortion is legal in Cuba but not in Chile. We compared total and congenital abnormalities related infant mortality in Cuba and Chile during 2008, based on vital statistics of both countries. In 2008, infant mortality rates in Chile were significantly higher than those of Cuba (7.8 vs. 4.7 per 1,000 live born respectively, odds ratio (OR) 1.67; 95% confidence intervals (Cl) 1.52-1.83). Congenital abnormalities accounted for 33.8 and 19.2% of infant deaths in Chile and Cuba, respectively. Discarding infant deaths related to congenital abnormalities, infant mortality rate continued to be higher in Chile than in Cuba (5.19 vs. 3.82 per 1000 live born respectively, OR 1.36; 95%CI 1.221.52). Considering that antenatal diagnosis is widely available in both countries, but abortion is legal in Cuba but not in Chile, we conclude that eugenic abortion may partially explain the lower infant mortality rate observed in Cuba compared to that observed in Chile.

    Full Text Available Porphyry Cu-Mo deposits have influenced surface water quality in high-Andes of north-central Chile since the Miocene. Water anomalies may reduce species abundance and diversity in alpine meadows as acidic and metal-rich waters are highly toxic to plants The study assessed the importance of surface water quality on plant abundance and diversity in high-alpine meadows at the Yerba Loca Natural Santuary (YLNS, central Chile (33°15' S, 70°18' W. Hydrochemical and plant prospecting were carried out on Piedra Carvajal, Chorrillos del Plomo and La Lata meadows the growing seasons of 2006 and 2007. Direct gradient analysis was performed through canonical correspondence analysis (CCA to look for relationships among water chemistry and plant factors. High variability in water chemistry was found inside and among meadows, particularly for pH, sulphate, electric conductivity, hardness, and total dissolved Cu, Zn, Cd, Pb and Fe. Data on species abundance and water chemical factors suggests that pH and total dissolved Cu are very important factor determining changes in plant abundance and diversity in study meadows. For instance, Festuca purpurascens, Colobanthus quitensis, and Arenaria rivularis are abundant in habitals with Cu-rich waters while Festuca magellanica, Patosia clandestina, Plantago barbata, Werneria pygmea, and Erigeron andícola are abundant in habitals with dilute waters.Los megadepósitos de pórfidos de Cu-Mo han influido sobre la calidad de las aguas superficiales en las zonas altoandinas del centro-norte de Chile desde el Mioceno.

El objetivo es averiguar si la riqueza, diversidad, abundancia y composición de las infracomunidades de parásitos son persistentes o no en el tiempo ontogenético y cronológico. Se recolectaron 10 taxa parasitarios en cerca del 89 % de los 63 huéspedes examinados, de los cuales ocho eran metazoarios. La búsqueda de protozoos se realizó sólo en los últimos 2 años. El 75 % de los ocho taxa de metazoos ocurrieron en los tres años, uno no estuvo presente en un año, y otro fue encontrado solamente en un año. La mayoría de los huéspedes examinados albergaba protozoos parásitos. La prevalencia de los protozoos Cryptobia sp. fue alta para ambos años, y menor en Trichodina sp. La longitud total de los huéspedes era un predictor relevante de las variaciones en la riqueza, abundancia, diversidad y composición infracomunitaria en el conjunto de los tres años. En cambio, el año de muestreo no lo fue, en particular al comparar entre huéspedes de similar longitud total. Estos resultados son similares a los encontrados en infracomunidades de parásitos de otras especies de peces en Chile, en que hay baja variabilidad en las propiedades agregadas de las infracomunidades en el tiempo cronológico. Se discute acerca de la extensión relativa del tiempo ontogenético en contraste al tiempo cronológico al ser probablemente ambos de importancia en las características de las infracomunidades, y se propone que se explore la medida en la cual estos resultados constituyen un patrón.Parasite infracommunities of the blenny Scartichthys viridis (Pisces: Blenniidae are compared among three samples taken within a 17-month period during three consecutive years (1999-2001, from intertidal pools at

  2. The GNSS Component of the Seismic Monitoring System in Chile

    Barrientos, S. E.

    2016-12-01

    Chile is amongst the most seismically active countries in the world. Since mid-XVI Century, a magnitude 8 or more earthquake has taken place every dozen of years, as an average. In the last 100 years, more than ten events with magnitudes around 8 or larger have taken place in this part of world. Three events with M>8 have taken place only in the last six years. The largest earthquake ever recorded took place in May, 1960, in southern Chile. Such extreme seismic activity is the result of the interaction of the Nazca, Antarctic, Scotia and South American plates in southwestern South America where Chile is located. These megathrust earthquakes exhibit long rupture regions reaching several hundreds of km with fault displacements of several tens of meters. At least eighteen of these earthquakes have generated local tsunamis with runups larger than 4 m -including events in 2010, 2014 and 2015- therefore it is mandatory to establish a system with capabilities to rapidly evaluate the tsunamigenic potential of these events. In 2013, the newly created National Seismological Center (CSN) of the University of Chile was tasked to upgrade the countrýs seismic network by increasing the numbers of real-time monitoring stations. The most important change to previous practices is the establishment of a GNSS network composed by 130 devices, in addition to the incorporation of 65 new collocated broadband and strong motion instruments. Additional 297 strong motion instruments for engineering purposes complement the system. Forty units -of the 130 devices- present an optional RTX capability, where satellite orbits and clock corrections are sent to the field device producing a 1-Hz position stream at 4-cm level. First records of ground displacement -using this technology-were recorded at the time of the largest aftershock (Mw=7.6) of the sequence that affected northern Chile in 2014. The CSN is currently developing automatic detectors and amplitude estimators of displacement from the

  3. Field survey of the 16 September 2015 Chile tsunami

    2016-04-01

    On the evening of 16 September, 2015 a magnitude Mw 8.3 earthquake occurred off the coast of central Chile's Coquimbo region. The ensuing tsunami caused significant inundation and damage in the Coquimbo or 4th region and mostly minor effects in neighbouring 3rd and 5th regions. Fortunately, ancestral knowledge from the past 1922 and 1943 tsunamis in the region along with the catastrophic 2010 Maule and recent 2014 tsunamis, as well as tsunami education and evacuation exercises prompted most coastal residents to spontaneously evacuate to high ground after the earthquake. There were a few tsunami victims; while a handful of fatalities were associated to earthquake induced building collapses and the physical stress of tsunami evacuation. The international scientist joined the local effort from September 20 to 26, 2015. The international tsunami survey team (ITST) interviewed numerous eyewitnesses and documented flow depths, runup heights, inundation distances, sediment deposition, damage patterns, performance of the navigation infrastructure and impact on the natural environment. The ITST covered a 500 km stretch of coastline from Caleta Chañaral de Aceituno (28.8° S) south of Huasco down to Llolleo near San Antonio (33.6° S). We surveyed more than 40 locations and recorded more than 100 tsunami and runup heights with differential GPS and integrated laser range finders. The tsunami impact peaked at Caleta Totoral near Punta Aldea with both tsunami and runup heights exceeding 10 m as surveyed on September 22 and broadcasted nationwide that evening. Runup exceeded 10 m at a second uninhabited location some 15 km south of Caleta Totoral. A significant variation in tsunami impact was observed along the coastlines of central Chile at local and regional scales. The tsunami occurred in the evening hours limiting the availability of eyewitness video footages. Observations from the 2015 Chile tsunami are compared against the 1922, 1943, 2010 and 2014 Chile tsunamis. The

    Resultados. R. prolixus presenta variabilidad genética moderada (Fst 0,057-0,15, entre las poblaciones domiciliadas se encontraron tasas de migración (Nm>1 que revelan flujo genético. Se encontró diferenciación genética de moderada-alta entre la población silvestre de Casanare y las poblaciones domésticas del centro del país (Tolima y Cundinamarca. Conclusión. Las poblaciones domiciliadas de R. prolixus son homogéneas debido a que existe flujo genético entre éstas; lo cual es favorable para el control químico, mientras que la población silvestre agrupa aparte de las domiciliadas. Se evidencia la necesidad de estudiar la estructura genética de los focos silvestres, sus posibles rutas de dispersión y el riesgo epidemiológico que representan.

    Las serpientes pertenecen a la clase reptiles, orden escamados y suborden ofidios. Surgieron durante el periodo cretáceo hace aproximadamente 120 millones de años. La evolución de las formas venenosas es un poco más reciente, posiblemente hace unos 30 millones de años. Actualmente se conocen unas 3200 especies de serpientes de las cuales unas 1300 son venenosas, agrupadas en cuatro familias: Colubridae (cazadoras opistoglifas, Elapidae (corales, Hydrophiidae (serpientes marinas y Viperidae (víboras subfamilia Crotalinae (de fosa. La víbora Bothriechis schlegelii, es una serpiente arborícola que se distribuye desde Centroamérica hasta Suramérica (Venezuela, Ecuador y Colombia. En Colombia la especie se encuentra en las 3 cordilleras, en los valles interandinos y en las llanuras del Caribe y del Pacífico hasta los 2.640 metros sobre el nivel del mar. Su talla máxima es de 83 cm y el accidente por ella ocupa el primer lugar en las zonas cafeteras y en el norte de Antioquia. Además a esta especie se le ha demostrado variación en el patrón de coloración en las regiones del Suroeste y norte de Antioquia.

    Full Text Available Soils with small variations in relief and under the same management system present differentiated spatial variabilities of their attributes. This variability is a function of soil position in the landscape, even if the relief has little expression. The aim of this work was to investigate the effects of relief shape and depth on spatial variability of soil chemical attributes in a Typic Hapludox cultivated with sugar cane at two landscape compartments. Soil samples were collected in the intercrossing points of a grid, in the traffic line, at 0-0.2 m and 0.6-0.8 m depths, comprising a set of 100 georeferenced points. The spatial variabilities of pH, P, K, Ca, Mg, cation exchange capacity and base saturation were quantified. Small relief shape variations lead to differentiated variability in soil chemical attributes as indicated by the dependence on pedoform found for chemical attributes at both 0-0.2 m and 0.6-0.8 m depths. Because of the higher variability, it is advisable to collect large number of samples in areas with concave and convex shapes. Combining relief shapes and geostatistics allows the determination of areas with different spatial variability for soil chemical attributes.Solos submetidos ao mesmo sistema de manejo em locais com pequena variação de relevo, manifestam variabilidade espacial diferenciada de seus atributos.

This impact is quantified through four indicators: product, employment, foreign investment and exports, and their variability allow the verification of the dissimilar vulnerability of each region and its dissimilar exposure to the risk of crisis contamination. The study is based on a conceptual frame that states that crisis continue to be more regional-like than global, and that there is a real geography of contamination.

    With this issue, Revista Médica de Chile will have been published uninterruptedly, for 130 years. Formal medical education had an early development since Chile became independent from Spain (1817). The first Medical Sciences Course was organized in 1833 by the Irish physician William C Blest. The Santiago Medical Society was founded in 1869 and its journal-Revista Médica de Chile--in 1872. Its first director was Dr. German Schneider. Revista Medica is the oldest serial publication in South America and the second oldest in the Spanish speaking world. This is a remarkable fact for a comparatively young country. With the creation of the Medical Society and Revista Medica, a process of continuous medical education was started and they became a real Graduate School. The Journal has adopted the main changes in knowledge and technology. Some important milestones of its development, during the second half of the 20th century, were the definition of its objectives and structure, the incorporation of peer review of manuscripts (even with foreign reviewers) the adoption of international guidelines for publication, its incorporation into the main biomedical journal indexes, the modernization of its printing process, the making of a computer generated index of all papers published since 1872, its incorporation into a digital library in INTERNET and the active participation of its editors in the World Association of Medical Journal Editors. The success of the journal is influenced by the independence that the Medical Society has conferred to the editors (all outstanding University Professors), as well as to the characteristics of an educational campus "invisible and without tumult" (Ingelfinger).

    There are no published studies on physical dating violence in college students in Chile, and campuses across the country currently lack systematized programs to prevent or respond to this public health problem. This is the first study to examine prevalence and predictors of physical dating violence victimization with a sample of female college students in Chile. A closed-ended questionnaire was administered to students enrolled in general education courses at a major public university. The prevalence of women's physical dating violence victimization was calculated, and generalized ordered logit models were used to estimate risk factors for such victimization (n = 441). Ancillary analyses examined associations of dating violence victimization with experiences of unwanted sexual contact and forced condom nonuse. Approximately 21% of subjects reported one or more incidents of physical dating violence not involving physical injury since age 14, and another 5% reported at least one incident resulting in physical injury during this time period. Risk factors identified in five sequential models were sexual abuse and witnessing of domestic violence in childhood, low parental education, residence away from the parental home, urban residence, and having had sexual intercourse. Maternal employment and religious participation had protective effects. Dating violence victimization was found to be significantly associated with experiences of unwanted sexual contact and forced condom nonuse. The study findings show a high prevalence of physical dating violence, strong associations between several sociodemographic factors and dating violence, and links between dating violence and sexual/reproductive risk. Our results indicate a need to expand attention to this public health problem in Chile as well as other developing countries, where research and prevention/response initiatives have generally been similarly limited. The findings also have important implications for the content of

    Chile's 1st case of AIDS was diagnosed in 1984. Some 250 AIDS cases and 1600 HIV positive persons have since been reported, although the actual number by some estimates may reach 5000. Chile, although in the initial stages of the epidemic, already has a serious problem which at present can only be combatted through education. It will be necessary to convince the population that significant modifications of sexual behavior are needed to control the spread of the disease. Education for AIDS prevention is a priority of the National Commission on AIDS (CONASIDA), which is basing its program on the premise that stable monogamy is the most natural form of expression of a couple. Manuals for prevention are under development, and the 1st, for health workers and the general population, is in process of publication. A series of pamphlets and educational videos for workers in sexually transmitted disease clinics are under development. Educational materials are also being created for specific groups such as university students and agricultural workers and for groups at high risk. A social communications campaign has been prepared and approved by the authorities, and is awaiting funding for dissemination. Education of the population is also a concern for the Catholic Church, which views reinforcement of the family and its mission of providing sex education as a primary means of preventing AIDS. CONASIDA is also responsible for epidemiological study of AIDS in Chile through surveillance of sentinel groups and in quality control of the blood supply. Condoms are to be distributed in sexually transmitted disease clinics for the purpose of AIDS prevention.

  18. On the generation of coastal lows in central Chile

    Rutllant, J.

    1994-07-01

    Previous studies of the coastal-low occurrences in central Chile have been aimed at the formulation of a conceptual model to explain observed features in connection with applied studies. The most prominent weather pattern associated with CL occurrences, (type A), coincides with the onset of a warm, middle-troposphere ridge over central Chile, and a surface high over northern Argentina. The synoptic forcing of the low is related to weak frontal disturbances that travel equatorwards. They result in a thickening of the marine layer that becomes blocked by the coastal escarpment, at the time of the onset of the ridge aloft. The blocking of the stable air above the subsidence inversion by the Andes is also hypothesized. The analysis of the subsidence inversion, the geometry of the coastal and Andes mountain ranges, and a scale analysis of the non-dimensional governing equations for the generation of the coastal lows, following the approach of Reason and Steyn (1990); leads to the conclusion that both blocking actions are strong and persistent in central Chile. An interactive mechanism between the upper and lower blocking effects is postulated to explain the cyclonic vorticity and the initial steering of the coastal lows. The scale analysis of the governing equations for the propagation stage of the low suggests that, departing for the South African case, non-linearity is important here, and that solitary Kelvin waves could be expected. Theoretical phase propagation speeds and Rossby radii are found to range between 8 and 15 m s-1 and 100-250 km, respectively. The importance of strong southerly winds ahead of the low and weak winds at its trailing edge is also stressed, as another major departure from the coastal-low behaviour elsewhere.

    Full Text Available This article examines how flexible work economy has been affecting a group of beauty salons’ workers in Santiago, Chile. They do not have a work contract and receive their payment as if they were giving an independent service, but depend on the rules their bosses impose them. The kind of work described in the article appears to be a new arrangement within the context of urban informality, which has present and future implications regarding social security and uncertainty. Drawing on ethnographic observation in four beauty salons, I describe how the embodied belief of being an independent worker helps to enact many skills required by the flexible work economy.

    To explore the work transitions of Chilean women. Observations and dialogue of Chilean women and their experiences in current and past work. A personal and historical reflection to understand the experiences of work for Chilean women. Exploring work transitions requires an understanding of the macro level historical impact on the participation of women in work in Chilean society. Macro level factors such as participation in the free labour market economy ultimately impacts on the individual choices of the women of Chile regarding their opportunities to transition into productive paid employment. The understanding of work transitions must consider the influences of the labour market economy.

    Full Text Available In 2007 (the last agricultural census, Chile had 308, 445 ha of fruit orchards: an increase of almost 32% from the previous census (1997. The most important species were table grapes (20%, avocados (13% and apples (12%. Some 22% of the fruit crops growing area corresponded to juvenile orchards; within the species with higher proportion of juvenile orchards were prunes (42% and blueberries (56%. Most orchards are located between latitude 27º18` S (Copiapó and 40º36´S (Puerto Varas. The industry is driven by the export component which accounts for more than 50% of the fruits produced. In the crop season 2009-2010, approximately 254 million boxes (around 2.5 million tons were exported, representing over US$ 3.5 million. Processed and fresh fruits represented 8.2 and 26.7% of the total forest and agricultural Chilean exports in 2008, respectively. The main markets for this fruits were USA/Canada (42% and Europe (32%. The fruit grower receives, on average, 12-16% of the total price of the fruit in its final destination. Each year the fruit industry employs 450.000 people directly, of which 1/3 are permanent. Even though the fruit industry employs the highest proportion of the agricultural labor and the growing area has increased in the last 20 years, the proportion of agricultural employment has decreased from 19.5% in 1989 to 10.8% in 2008. It might also be noted that Chile invests only 0.7% of the GDP in research. In the last 40 years, the fruit industry has been a motor for the Chilean economic development, but the lower rates of currency exchange, the rising costs of energy (oil, electricity, and the increasing scarcity of hand labor have drastically reduced the profitability and are putting at risk the viability of a large proportion of the fruit orchards in Chile. It is estimated that this season around 65% of the orchards will have a negative economic balance in their operations. Higher investment in research, improvements in fruit quality

    Chile, a middle-income country, recently joined Israel and Singapore as the world's only countries to require reciprocity as a precondition for organ transplantation. The Chilean reform includes opt-out provisions designed to foster donation and priority for organ transplantation for registered people. Although the reform has had serious difficulties in achieving its mission, it can be reviewed by other countries that seek to address the serious shortage of organs. As increased organ donation can substantially enhance or save more lives, the effect on organ availability due to incentives arising from rules of preference should not be underestimated.

O presente trabalho foi realizado com os objetivos de conhecer melhor a variabilidade genética dessa macrófita e relacionar essa variabilidade com a resposta à aplicação do herbicida glyphosate. Para isso, foram coletados indivíduos em 12 corpos hídricos em diferentes cidades do território nacional (Americana, Cambaratiba, Curitiba, Itapura, Jaboticabal, Lagoa Santa, Piraí, Rio Grande, Rubinéia, Salto Grande, Santa Gertrudes e Três Lagoas. Os acessos foram caracterizados pelo uso de marcadores RAPD (DNA Polimórfico Amplificado ao Acaso, que permitiram, com o auxílio de iniciadores aleatórios, a caracterização dos locos polimórficos identificados por uma matriz de ausência e presença de bandas. Utilizando essa matriz, a análise de agrupamento permitiu nítida classificação dos acessos em três grupos com diferenças genéticas entre eles. Um ensaio de controle químico, com plantas mantidas em vasos plásticos (5 L e pulverizadas com o herbicida glyphosate nas concentrações de 0,0, 0,6, 1,2, 1,8 e 2,4 kg ha-1, identificou, utilizando avaliações aos 7, 14 e 21 dias após aplicação, que as duas maiores doses promoveram melhor efeito herbicida.

    RESUMEN Introducción El mapeo de las diferentes regiones del estómago y el número de fragmentos de mucosa gástrica disponibles para evaluación histopatológica son fuentes importantes de variación en el momento de clasificar y hacer la gradación de la gastritis crónica. Objetivos Estimar la sensibilidad del número de fragmentos de mucosa gástrica necesarios para establecer los diagnósticos de gastritis atrófica con metaplasia intestinal (MI), displasia y estado de infección por Helicobacter pylori. Además evaluar la variabilidad intra-observador en la clasificación de estas lesiones precursoras del cáncer gástrico. Materiales y métodos En una cohorte de 6 años de seguimiento se evaluaron 1,958 procedimientos de endoscopia realizados por dos gastroenterólogos. En cada procedimiento y de cada participante se obtuvieron 5 biopsias de mucosa gástrica que representaban antro, incisura angularis y cuerpo. Un único patólogo hizo la interpretación histológica de las 5 biopsias y proporcionó un diagnóstico definitivo global que se utilizó como patrón de referencia. Cada fragmento de mucosa gástrica examinado condujo a un diagnóstico individual para cada biopsia que se comparó con el patrón de referencia. La variabilidad intra-observador se evaluó en 127 personas que corresponden a una muestra aleatoria de 20% del total de endoscopias hechas a los 72 meses de seguimiento. Resultados La sensibilidad del diagnóstico de MI y displasia gástrica aumentó de manera significativa con el número de fragmentos de mucosa gástrica evaluados El sitio anatómico de mayor sensibilidad para el diagnóstico de MI y displasia fue la incisura angularis. Para descubrir H. pylori se logró alta sensibilidad con el estudio de un solo fragmento de mucosa gástrica (95.9%) y fue independiente del sitio de obtención de la biopsia. El acuerdo intra-observador para el diagnóstico de gastritis crónica fue 86.1% con valor kappa de 0.79 IC 95% (0.76-0.85). Las

O DNA genômico de cada acesso foi extraído, e doze iniciadores decâmeros foram utilizados para a obtenção de marcadores moleculares RAPD, que foram convertidos em matriz de dados binários, a partir da qual foram estimadas as distâncias genéticas entre os acessos e realizadas análises de agrupamento e de dispersão gráfica. Foram obtidos 196 marcadores para P. nitida, dos quais 63,81% foram polimórficos. As distâncias genéticas entre os acessos de maracujá variaram de 0,031 a 0,614 e, considerando apenas P. nitida, de 0,031 a 0,417. Os marcadores moleculares demonstraram alta variabilidade genética dos acessos de P. nitida. Menores distâncias genéticas foram verificadas entre os acessos originados do mesmo estado. Considerando-se os acessos de um mesmo estado, menores distâncias genéticas foram verificadas entre os acessos provenientes de tipos fitofisionômicos próximos.

    Full Text Available In the last years relationship between autonomic nervous system (ANS function and cardiovascular mortality has been recognized. This has motivated research to find quantitative markers of autonomic balance. Heart rate variability (HRV is one of the most promising methods. HRV is defined as the variations occurred in the time interval between consecutive heartbeats and it is thought to depend on the ANS modulation. Tacogram (recording of cardiac frequency in time is used to evaluate HRV. The study of HRV started 30 years ago and has gained importance in the last 10 years. There are several methods to evaluate HRV. The most accepted today are frequency domain methods (spectral analysis. Spectral analysis consists in the decomposition in order to obtain the spectral components. There are high frequency components (HF, related to vagal tone, low frequency (LF components, related to the modulation of both sympathetic and vagal modulation, and very low frequency components which have not been related to any physiological variable. Time domain methods, are basically statistic and evaluate variability using means and standard deviations. These methods seem to have less advantages than spectral methods. HRV is correlated with physiological adaptations to changes in internal and external environment and to the presence of diseases. This article presents the main techniques in the time and frequency domains and their relationship with physiological changes and specific diseases. En los últimos años, se ha reconocido la relación existente entre el funcionamiento del sistema nervioso autónomo (SNA y la mortalidad cardiovascular. Esto ha motivado la búsqueda de marcadores cuantitativos del balance autonómico. La Variabilidad de la Frecuencia Cardíaca (VFC representa uno de los más promisorios.

    Full Text Available The Pink Disease is caused by Erythricium salmonicolor, which attacks broad hosts, such as citrus, coffee, rubber, Eucalyptus spp. and Acacia spp., infecting mainly branches. This disease became a serious problem in Brazil, reducing the citrus production up to 10%. However the genetic diversity and compatibility of the fungus E. salmonicolor from Brazilian citrus plants is not yet evaluated. Therefore, the aims of this study were to evaluate: i the genetic variability of E. salmonicolor in the São Paulo and Minas Gerais States by the RAPD technique, and ii the vegetative compatibility between these isolates. After RAPD analysis, six distinct groups were observed without correlation between the isolation site or host species. In the vegetative compatibility test, the contact of fungal hyphae between all evaluated crosses was observed, of which 84% presented hyphal fusion. Although the compatibility between strains was observed, no correlation between RAPD haplotypes and hyphal anastomosis was verified. These results show the importance of future studies on the sexual cycle of E. salmonicolor, since hyphal fusion, which precedes the formation of heterokaryons (sexual and parasexual reproduction that could be responsible for the genetic variability in this species.A rubelose é uma doença causada pelo fungo Erythricium salmonicolor que atinge muitos hospedeiros, como citros, café, seringueira, eucalipto, Acacia sp., infectando principalmente os galhos. Rubelose é um sério problema para o Brasil, reduzindo a produção de citros em valores próximos de 10%. A diversidade do fungo E. salmonicolor em cultivares brasileiras ainda não foi avaliada. Este trabalho teve como objetivos: i avaliar a variabilidade genética, por meio de RAPD, de 19 isolados de E. salmonicolor provenientes de diferentes regiões citrícolas de São Paulo e Minas Gerais, ii avaliar a compatibilidade vegetativa e fusão de hifas do fungo E. salmonicolor.

    Full Text Available Las especies de moluscos exóticas dulceacuícolas registradas en esta contribución, corresponden a ejemplares recolectados en humedales en acuarios comerciales o interceptados en barreras aduaneras, así como de referencias bibliográficas. Un total de 7 especies pertenecientes a 6 géneros fueron identificadas: Pomacea bridgesii; Helobia sp.; Thiara (Melanoides tuberculata; Melanoides maculata; Physa sp.; Physella venustula y Biomphalaria sp. Melanoides maculata fue recolectada en el río Lluta y clasificada como especie criptogénica. Los moluscos exóticos recolectados podrían tener éxito en su establecimiento si se considera la vulnerabilidad de los hábitats nativos debido al cambio en las condiciones climáticas globales o a las elevaciones térmicas producidas en el sector costero por los fenómenos de El Niño. En este sentido, las especies subtropicales observadas se podrían considerar como no endémicas y vectores potenciales de zoonosis parasitarias. Las principales vías de introducción de moluscos dulceacuícolas exóticos se derivaron del intercambio comercial, por lo cual, y frente a su incremento interregional, se hace necesario recopilar datos ecológicos y taxonómicos adecuados que permitan evaluar el riesgo de su establecimiento, así como servir de base para la aplicación de futuros tratamientos en bioseguridad.The exotic freshwater mollusk species we report here were collected in wetlands, commercial aquariums, or were given to us by government officials who intercepted some exotic species at customs offices.

    Full Text Available Estudios epidemiológicos han demostrado la relación entre los contaminantes atmosféricos y el incremento en la mortalidad por causas cardiovasculares, en especial en personas con enfermedad cardiopulmonar previa. Sin embargo, los mecanismos fisiopatológicos mediante los cuales estos padecimientos ocurren no son bien conocidos. Se ha sugerido que una de las vías mediante las cuales las partículas suspendidas respirables y otros contaminantes producen su efecto es alterar la regulación del corazón por el sistema nervioso autónomo. El análisis de los cambios en la variabilidad de la frecuencia cardiaca (VFC es un indicador de efecto sobre este mecanismo. En este trabajo se realiza una revisión de las bases fisiológicas de este método, de sus ventajas y limitaciones y de los resultados que se obtienen al relacionarlo con la exposición a contaminantes atmosféricos. A partir del análisis de la literatura disponible, se sugieren alternativas relacionadas con el diseño de los estudios, la selección de poblaciones en riesgo, los métodos para evaluar la exposición y los métodos de análisis estadístico que pueden servir para utilizar mejor el análisis del registro electrocardiográfico ambulatorio en relación con los riesgos cardiacos por exposición a contaminantes atmosféricos.

    Full Text Available La contaminación atmosférica afecta a ciudades y países de todo el planeta. Uno de los conta- minantes atmosféricos más comunes es el material particulado atmosférico, que tiene directa incidencia sobre la salud de la población (OMS, 2006. Las condiciones meteorológicas definen en gran medida su concentración a nivel troposférico. Por consiguiente, el objetivo del presente trabajo es analizar la variabilidad temporal del PM10 de la ciudad de Bahía Blanca (Argentina, estableciendo posibles relaciones entre dicho comportamiento y variables físicas y antropogéni- cas que pueden incidir en su dinámica. Se observó que la concentración del material particulado en Bahía Blanca se relaciona con factores naturales y antropogénicos. El flujo vehicular y las actividades portuarias, principalmente el transporte y almacenamiento de granos, favorecen la producción del contaminante. Esto se manifiesta en una distribución diferencial a lo largo del día y entre días laborables y no laborables. La alta concentración de PM10 se ve afectada por la presencia de vientos de componente Norte y de altas velocidades, que suelen estar acompañados de nubes de polvo y humo. También fenómenos naturales, como la erupción del Complejo Vol- cánico Puyehue-Cordón Caulle, inciden en los valores hallados.

    Full Text Available A acerola (Malpighia emarginata é uma frutífera tropical encontrada nativa na América Central e no Norte da América do Sul, sendo de grande importância econômica e social devido ao seu alto conteúdo de vitamina C (ácido ascórbico. Pomares de acerola têm sido preferencialmente estabelecidos por métodos de propagação vegetiva. No entanto, a propagação sexuada por sementes é igualmente utilizada e permite revelar um alto grau de polimorfismo na cultura, possibilitando a identificação de genótipos portadores de características de interesse agronômico. Vinte e quatro acessos de acerola, pertencentes ao Banco Ativo de Germoplasma da Universidade Estadual de Londrina, foram analisados, usando marcadores RAPD (Random amplified Polymorphic DNA e obtidos com iniciadores (primers de seqüência simples repetidas (SSRs. Um total de 164 e 73 marcadores foram obtidos com primers de RAPD e SSR, respectivamente. Os marcadores obtidos foram analisados, usando o método de agrupamentos UPGMA. A análise comparativa dos dendrogramas gerados com os primers de RAPD e com os primers SSR mostrou que, enquanto alguns acessos se associaram em grupos diferentes, outros apresentaram a mesma associação. Entretanto, maior polimorfismo entre acessos foi detectado com os primers de RAPD. A análise dos resultados revelou a alta variabilidade contida na coleção, permitindo associar o grau de similaridade genética, obtido por marcadores de DNA, com caracteres morfológicos compartilhados entre os acessos.

A área experimental foi cultivada sob um convencional preparo de solo, onde foi implantada a cultura do milho. Esta foi definida por uma malha quadrangular de 70 m x 70 m, selecionada a partir de características visuais homogêneas, onde se estabeleceu 64 pontos georeferenciados distanciados de 10 em 10 m. As avaliações da resistência à penetração foram realizadas até 40 cm de profundidade em três estágios distintos da cultura (V6, VT e R6. As análises geoestatísticas e a geração dos mapas de variabilidade foram realizadas com o uso da versão gratuita do programa computacional GS+. Os resultados apresentam diferença entre as avaliações em cada perfil estudado, apresentando diferenciações nos modelos, na classificação da dependência espacial e no alcance desta dependência, o que dificulta a tomada de decisões pois estas mensurações sofrem influência de inúmeros fatores. O estudo permitiu uma maior visualização das influências nas medidas de resistência à penetração e alerta profissionais da área no uso destas para identificação de camadas compactadas.

    Full Text Available A grande maioria dos ensaios de manejo e fertilidade do solo utiliza o método de delineamentos experimentais, segundo o qual as observações devem ser independentes umas das outras e as parcelas experimentais, uniformes quanto aos atributos estudados. A hipótese de independência entre as amostras apenas pode ser satisfeita e verificada na prática, se a amostragem contiver informações geográficas, como, por exemplo, as coordenadas com referências a um eixo arbitrário para possibilitar análises da geoestatística. O objetivo deste trabalho foi estudar a variabilidade espacial de alguns atributos químicos e granulométricos do solo dentro de uma parcela experimental e mostrar o uso da geoestatística para analisar os dados. O campo estudado localiza-se no Centro Experimental de Campinas do Instituto Agronômico, Campinas (SP, em um latossolo roxo distrófico sob preparo convencional nos últimos dez anos. Marcou-se uma parcela de 30 m por 30 m a cada 5 m em duas direções, resultando em um reticulado quadrado de 49 pontos de amostragem. Em cada ponto, coletaram-se amostras de solo das camadas 0-25 cm e 25-50 cm de profundidade, as quais foram levadas ao laboratório, secas ao ar, peneiradas em uma malha de 2 mm e submetidas às análises granulométricas e químicas de rotina para obter teor de argila, teor de silte, delta pH, soma de bases (S, capacidade de troca catiônica (CTC e saturação por bases (V%. Para a análise de variabilidade espacial, utilizou-se a geoestatística. Os coeficientes de variação encontrados são mais altos na camada 0-25 cm do que na 25-50 cm, provavelmente devido à região de maior alteração com cultivo. Foi encontrada dependência espacial para todos os atributos analisados para a camada 0-25 cm, e dependência fraca para a camada 25-50 cm. Considerando que o campo engloba apenas uma área de 30 m por 30 m, conclui-se que a variabilidade encontrada para os atributos químicos do solo foi grande e

    Full Text Available Objective: To establish variations in clinical practice associated with maintaining the patency of peripheral intravenous catheters (PIC and to determine to what extent such clinical practice falls within the limits of the available scientific evidence, based on a random sample of Spanish public hospitals. Methods: A cross-sectional, descriptive study was carried out in non-psychiatric public hospitals and their associated medical and surgical units. Cluster (hospitals, stratified (hospital size, and single-stage (all units sampling was applied. A questionnaire was mailed to all of the units involved. Results: A sample of 341 valid questionnaires was analysed (response rate 54.5%. Only one praxis-modality was carried out in the majority of units. Intermittent flushing and heparin saline versus normal saline was the most frequent modality employed, over those of continuous flushing and non-heparinised saline. There was a high degree of variation in the quantity of heparin administered: 81.7% when flushing was carried out with heparinised saline and 48.2% when it was conducted with concentrated heparin. About 40% of this variation was associated with the hospital in question, rather than with the unit. The clinical practice fell within the limits of available scientific evidence in fewer than half of the units studied. Conclusions: There was a high degree of variability in the practice of maintaining PIC patency. A significant part of this variation was attributable to the hospital in which the practice was carried out. Moreover, most of this practice was carried out beyond the limits of available scientific evidence.Objetivo: Determinar la variabilidad de la práctica clínica en el mantenimiento de la permeabilidad de los catéteres venosos periféricos en una muestra aleatoria de hospitales españoles y determinar en qué medida esta práctica se realiza dentro del rango de la evidencia disponible.

    In the last two decades, Chile has experienced advances in economical development and global health indicators. However, gender inequities persist in particular related to access to health services and financing of health insurance. To examine gender inequities in the access to health care in Chile. An analysis of data obtained from a serial national survey applied to assess social policies (CASEN) carried out by the Ministry of Planning. During the survey 45,379 and 48,107 dwellings were interviewed in 1994 and in 1998, respectively. Women use health services 1.5 times more often, their salaries are 30% lower in all socioeconomic strata. Besides, in the private health sector, women pay higher insurance premiums than men. Men of less than two years of age have 2.5 times more preventive consultations than girls. This difference, although of lesser magnitude, is also observed in people over 60 years. Women of high income quintiles and users of private health insurance have a better access to preventive consultations but not to specialized care. An improvement in equitable access of women to health care and financing is recommended. Also, monitoring systems to survey these indicators for women should improve their efficiency.

    A 3 a data set of isotopes in precipitation from northern Chile show a very distinct pattern, with δ 18 O values ranging between -18 and -15per thousand at high altitude stations, compared to δ 18 O values between -10 and -6per thousand at the lower altitude areas. The 18 O-depleted values observed in the high altitude area, the Altiplano, are related to processes that affect the air masses that originated over the Atlantic, cross the Amazon Basin (continental effect), ascend the Andes (altitude effect) and precipitated (convective effect) in the Altiplano. It is postulated that a second source of moisture, associated with air masses from the Pacific, may contribute to the 18 O-enriched values observed in the lower altitude areas. Similar isotopic patterns are documented in springs and groundwater indicating that the data presented in this paper are an accurate representation of the long term behavior isotopic composition of rain in northern Chile.

    2000-01-01

    In South America, there are about fifteen Rhagoletis species that live in association with wild and cultivated Solanaceae host plants (Foote 1981, Frias 1992). The principal information on taxonomy for these species is the morphology of adults. Thus, in the genus Rhagoletis, in general, there is little information about immature stages especially on first and second larva instars (Steck et al. 1990, Carrol and Wharton 1989, Steck and Wharton 1988, Persson 1963, White and Elson-Harris 1992, Hernandez-Ortiz 1992, 1993, Frias et al. 1993). Presently, in Chile, there are 4 species associated with Solanaceae host plants. R. tomatis Foote and R. nova (Schiner) are associated with cultivated Solanaceae Lycopersicum esculentum Miller or cultivated tomatoes and Solanum muricatum Aiton or sweet cucumber respectively. R. conversa Bethes has two Solanum host plants, S. nigrum L. and S. tomatillo (Remy) Phil. F. (Frias et al. 1984). The host for R. penela Foote is unknown. Moreover, in the last few years, a population on wild plums of the Myrobalan variety (Rosaceae) was detected (Gonzalez 1989). At present, there is no information about the origin and taxonomy of this population. In this work, we have studied the morphology of eggs, three instar larvae, pupae and adults of this population associated with wild plums as well as aspects of its geographical distribution in Chile

    This article examines, from a human rights perspective, the experience of women, and the practices of health care providers regarding abortion in Chile. Most abortions, as high as 100,000 a year, are obtained surreptitiously and clandestinely, and income and connections play a key role. The illegality of abortion correlates strongly with vulnerability, feelings of guilt and loneliness, fear of prosecution, physical and psychological harm, and social ostracism. Moreover, the absolute legal ban on abortion has a chilling effect on health care providers and endangers women's lives and health. Although misoprostol use has significantly helped to prevent greater harm and enhance women's agency, a ban on sales created a black market. Against this backdrop, feminists have taken action in aid of women. For instance, a feminist collective opened a telephone hotline, Linea Aborto Libre (Free Abortion Line), which has been crucial in informing women of the correct and safe use of misoprostol. Chile is at a crossroads. For the first time in 24 years, abortion law reform seems plausible, at least when the woman's life or health is at risk and in cases of rape and fetal anomalies incompatible with life. The political scenario is unfolding as we write. Congressional approval does not mean automatic enactment of a new law; a constitutional challenge is highly likely and will have to be overcome.

    The Peru Chile Current ecosystem is characterized by high biological productivity and important fisheries. Although this system is likely to be severely affected by climate change, its response to current global warming is still uncertain. In this paper we analyze 10-166 year old sediments in two cores collected in Mejillones Bay, an anoxic sedimentary setting favorable for preservation of proxies. Based on a 166 year chronology we used indicators of bottom water oxygenation proxies (Mo, V, S, and the (lycopane+n-C35)/n-C31) ratio) and surface water productivity (biogenic opal, counts of diatom valves, biogenic Ba, organic carbon and chlorins) to reconstruct environmental variations in Mejillones Bay. We find that at decadal scales, and during the last two centuries, a shift in the coastal marine ecosystem off Northern Chile took place which was characterized by intense ENSO-like activity and large fluctuations in biological export productivity, in bottom water oxygenation, and increased eolic activity (inferred from Ti/Al and Zr/Al). On top of this short-term variability, a gradual increase of sulfidic conditions has occurred being even more intensified since the early 1960s.

    Toxoplasmosis, cosmopolitan parasitic zoonosis often found in humans, is transmitted mainly by food and water, and is considered a significant risk of morbidity and mortality in pregnant women, newborns and immunocompromised patients. To identify the information about this zoonosis and its first reports in Chile. Review of publications in Pubmed, Mesh search of systematic reviews, case studies, cross-sectional studies, systematic reviews, meta-analysis and specialty publications. In addition, other publications in parasitology journals were analyzed. There are reports of the presence of this disease in Chile for 60 years. During this time several differences in prevalence depending on geographic location, age and education level of the population have been detected. There is low epidemiological vigilance and lack of specific official preventive measures for this disease, despite the possible introduction of new parasite genotypes of an increased virulence and pathogenicity in the country through the importation of meat. New enigmas have arisen in relation to this disease associating it with Alzheimer, Parkinson's disease, autism, learning disabilities, among others.

    This paper aims to describe the current challenges to recruitment of psychiatrists in Chile, and investigate factors related to interest in psychiatry from medical students of the Chilean Biobío Region. An online survey was completed by 39 medical students currently performing the internship. This survey included questions regarding socio-demographic aspects, probability of choosing a medical speciality, influencing factors on the choice of the medical speciality, and personal features. Students were separated in two groups for the analysis based on their likelihood of choosing psychiatry as a career. A total of 35.9% of the respondents showed some degree of interest in psychiatry. Factors considered important by the respondents were academic opportunities, training vacancies, and balance between job and personal life. The low participation in the study does not allow the extrapolation of data to the national situation, and may represent response bias to those already interested in psychiatry as a career. However, Chile has an average psychiatrist rate per number of inhabitants for the region, but an uneven distribution of this resource. National policies must be focused on this issue in order to reduce the gap in mental healthcare.

    Current geographic patterns of biodiversity are a consequence of the evolutionary history of the lineages that comprise them. This study was aimed at exploring how evolutionary features of the vascular flora of Chile are distributed across the landscape. Using a phylogeny at the genus level for 87% of the Chilean vascular flora, and a geographic database of sample localities, we calculated phylogenetic diversity (PD), phylogenetic endemism (PE), relative PD (RPD), and relative PE (RPE). Categorical Analyses of Neo- and Paleo-Endemism (CANAPE) were also performed, using a spatial randomization to assess statistical significance. A cluster analysis using range-weighted phylogenetic turnover was used to compare among grid cells, and with known Chilean bioclimates. PD patterns were concordant with known centers of high taxon richness and the Chilean biodiversity hotspot. In addition, several other interesting areas of concentration of evolutionary history were revealed as potential conservation targets. The south of the country shows areas of significantly high RPD and a concentration of paleo-endemism, and the north shows areas of significantly low PD and RPD, and a concentration of neo-endemism. Range-weighted phylogenetic turnover shows high congruence with the main macrobioclimates of Chile. Even though the study was done at the genus level, the outcome provides an accurate outline of phylogenetic patterns that can be filled in as more fine-scaled information becomes available.

  20. Configuración de la homosexualidad medicalizada en Chile

    Directory of Open Access Journals (Sweden)

    Juan Rolando Cornejo

    Full Text Available Este artículo realiza un análisis histórico de la producción intelectual chilena en torno a la homosexualidad y constata una permanencia del paradigma medicalizador, verificable hasta la actualidad. Tal paradigma, su conceptualización y representación, además de influenciar imaginarios sociales, dan lugar a la homofobia y a las dificultades para introducir reformas pro derechos de la comunidad LGBT. Sus antecedentes inmediatos se encuentran en el higienismo y en intentos modernizadores acaecidos en Chile durante las primeras décadas del siglo XX.

    A 3 a data set of isotopes in precipitation from northern Chile show a very distinct pattern, with {delta}{sup 18}O values ranging between -18 and -15per thousand at high altitude stations, compared to {delta}{sup 18}O values between -10 and -6per thousand at the lower altitude areas. The {sup 18}O-depleted values observed in the high altitude area, the Altiplano, are related to processes that affect the air masses that originated over the Atlantic, cross the Amazon Basin (continental effect), ascend the Andes (altitude effect) and precipitated (convective effect) in the Altiplano. It is postulated that a second source of moisture, associated with air masses from the Pacific, may contribute to the {sup 18}O-enriched values observed in the lower altitude areas. Similar isotopic patterns are documented in springs and groundwater indicating that the data presented in this paper are an accurate representation of the long term behavior isotopic composition of rain in northern Chile.

    The number of physicians available in a given country, their efficiency, quality and specialization is of utmost epidemiological importance. To evaluate the availability of physicians in Chile. The information about the number of physicians in Chile up to the year 2004, was obtained from the Ministry of Health, national universities and the register of immigrant physicians since 1950. The total number of physicians licensed to practice was 25,542, of whom 2,700 are immigrants. The physician/inhabitant ratio increased from 1/921 in 1998 to 1/612 in 2004. The greater impact in the increment of available physicians was given by the immigration of professionals and by the increase in the number of physicians graduated from national universities, mainly from the new private universities. Forty two percent of physicians work at public services and 61% of these are certified specialists. The regional distribution of general practitioners and basic specialists is adequate. Along the country, the mean physician/beneficiary ratio is 8.45/10,000, the specialist/beneficiary ratio is 4.9/10,000 and the general practitioner/beneficiary ratio is 2.3/10,000. The national information of available physicians, especially in the private sector, should be improved. Immigration of physicians should be regulated, maintaining validation examinations and a National Medical Test to assess medical proficiency should be instituted.

    To assess the distribution of financial burden in Chile, with a focus on the burden and progressivity of out-of-pocket payment. Based on the principle of ability to pay, we explore factors that contribute to inequities in the health system finance and issues about the burden of out-of-pocket payment, as well as the progressivity and redistributive effect of out-of-pocket payment in Chile. Our analysis is based on data from the 2006 National Survey on Satisfaction and Out-of-Pocket Payments. Results from this study indicate evidence of inequity, in spite of the progressivity of the healthcare system. Our analysis also identifies relevant policy variables such as education, insurance system, and method of payment that should be taken into consideration in the ongoing debates and research in improving the Chilean system. In order to reduce the detected disparities among income groups, healthcare priorities should target low-income groups. Furthermore, policies should explore changes in the access to education and its impact on equity.

    Catastrophe models help (re)insurers to understand the financial implications of catastrophic events such as earthquakes and tsunamis. In earthquake-prone regions such as Chile,(re)insurers need more sophisticated tools to quantify the risks facing their businesses, including models with the ability to estimate secondary losses. The 2010 (M8.8) Maule (Chile) earthquake highlighted the need for quantifying losses from secondary perils such as tsunamis, which can contribute to the overall event losses but are not often modelled. This paper presents some key modelling aspects of a new earthquake catastrophe model for Chile developed by Impact Forecasting in collaboration with Aon Benfield Research partners, focusing on the tsunami component. The model has the capability to model tsunami as a secondary peril - losses due to earthquake (ground-shaking) and induced tsunamis along the Chilean coast are quantified in a probabilistic manner, and also for historical scenarios. The model is implemented in the IF catastrophe modelling platform, ELEMENTS. The probabilistic modelling of earthquake-induced tsunamis uses a stochastic event set that is consistent with the seismic (ground shaking) hazard developed for Chile, representing simulations of earthquake occurrence patterns for the region. Criteria for selecting tsunamigenic events (from the stochastic event set) are proposed which take into consideration earthquake location, depth and the resulting seabed vertical displacement and tsunami inundation depths at the coast. The source modelling software RuptGen by Babeyko (2007) was used to calculate static seabed vertical displacement resulting from earthquake slip. More than 3,600 events were selected for tsunami simulations. Deep and shallow water wave propagation is modelled using the Delft3D modelling suite, which is a state-of-the-art software developed by Deltares. The Delft3D-FLOW module is used in 2-dimensional hydrodynamic simulation settings with non-steady flow

    Different Seed Selection and Conservation Practices for Fresh Market and Dried Chile Farmers in Aguascalientes, Mexico. The process of selecting and saving seed is the most basic and oldest of agricultural practices. In today's modern and highly capital-intensive agriculture, seeds are often treated like another chemical input. This study sought to examine seed selection and saving practices among chile farmers in Aguascalientes, Mexico, where both industrial and traditional agriculture are practiced. We observed a clear division among farmers who plant chile peppers commercially. Sixty-eight chile pepper farmers were surveyed in order to document seed selection and saving practices. Fifteen respondents (22%) planted chile peppers destined for the fresh market and all utilized purchased commercial seed of F1 hybrid varieties. Fifty-three farmers (78%) planted chiles to be dried and either saved their own or purchased seeds that others had saved and selected. Farmers who saved their own seed sought to maintain an ideotype, rather than directionally select for certain traits, much like Cleveland et al. (2000) chronicled in central Mexican maize farmers. Farmers would benefit from a participatory plant-breeding program in order to maintain productive seed stock for the continued cultivation of dried chile pepper in the state.

    Drought and water scarcity are important hazards and can lead to severe socio-economic impacts in many regions of the world. Given the interlinked interactions and feedbacks of hydrological droughts and their impacts and management, we need tools to evaluate these complexities and effects on the availability of water resources. Here we use a real-world case study of the Huasco basin (Northern Chile) in which we quantify the influence of human activities on hydrological drought signals. In this arid region, Andean snowmelt provides water essential for users, with agriculture acting as the main water consumer (85% of total). An increasing water demand from different water sectors (agriculture, mining, and domestic water usage) has increased pressure on available water and its management. Consequently, the Santa Juana dam was built by 1995 to increase irrigation security for downstream users, and recent management and restrictions have been established with the objective to limit impacts of hydrological droughts across the basin. The feedbacks between water availability and water management are explored for this water stressed region in Chile. Hydro-meteorological (e.g. precipitation, temperature, streamflow, reservoir levels) variables have been analysed to assess trends and drought patterns. Data over the past three decades has indicated a decrease in surface water supply, with the basin entering a situation of water scarcity during the recent multiyear drought (2007 - to-date), partly caused by meteorological drought and partly by abstraction. During this period, water supply failed to meet the demands of water users, resulting in the implementation of water restrictions. As well as the necessary continuous hydro-meteorological data, here we used information on human water users and scenario modeling, allowing for the analysis and quantification of feedbacks. This work highlights the importance of local knowledge, especially in understanding water laws, rights
