We compared biological and chemical parameters in surface waters of the Gulf of San Jorge to better understand carbon export and the factors that control phytoplankton production in an area of the Argentinian Continental Shelf, a vastly under sampled region of the SW Atlantic Ocean. In April of 2012, we estimated new and regenerated primary production in the Gulf by measuring nitrate and ammonium uptake, respectively. We also measured macronutrient, and in situ chlorophyll-a concentrations, which were compared to chlorophyll-a estimates from remote sensing. Although the Gulf of San Jorge presents high levels of chlorophyll-a and primary production, the relationship between these parameters is not straightforward. Previous studies showed that surface chlorophyll-a explains only part of the variance in euphotic-zone integrated primary production, and that satellite-derived chlorophyll-a underestimates in situ primary production. Our results showed large spatial variability in the Gulf, with transitional physico-chemical conditions, such as fronts, that could favor an increase in biological production. In situ chlorophyll-a concentrations were highest at the mid-shelf station (6.0 mg m- 3) and lowest at the northernmost location by an order of magnitude. Remote sensing measurements of chlorophyll-a underestimated our in situ chlorophyll-a concentrations. Total nitrogen (nitrate + ammonium) uptake showed relatively similar rates throughout the study area (≈ 130 nM-N d- 1), except in the northernmost station where it was much lower (53 nM-N d- 1). This north region had a distinct water mass and maximal levels of macronutrients (nitrate ≈ 6 μM, ammonium ≈ 1.2 μM, phosphate ≈ 1.2 μM and silicic acid ≈ 4 μM). For the entire sampling region, chlorophyll-a concentrations strongly correlated with total nitrogen uptake (r = 0.76, n = 8, p < 0.05) and new primary production (r = 0.78, n = 8, p < 0.05). Values of the f-ratio were 0.9 in mid-shelf, and ranged

Baseline concentration levels of As, B, Ca, Cd, Cr, Cu, Co, Fe, Mg, Mn, Mo, Ni, P, Pb, Se, V, and Zn were determined for Porphyra columbina and Ulva sp. collected from three locations along San Jorge Gulf, in Patagonia Argentina. Elements were quantified by inductively coupled plasma-optical emission spectrometry, with the exception of lead and cadmium in some samples which were determined by electrothermal atomic absorption spectrometry. Three stations with different exposure degree to human activities, Bahia Solano, the mouth of Arroyo La Mata stream and Punta Maqueda, were selected as sampling points. The results showed a wide range of metal retention capacity between the two studied species. Regarding the levels of pollutants found in the researched sites, Punta Maqueda seemed to be less influenced by anthropogenic activities than the other two sites except for Cd. Taking into account their toxicities seasonal variations in Pb and Cd levels were studied in both algae in Punta Maqueda. Maximum concentrations of Cd (9.8 μg g -1 dry wt.) were observed in P. columbina during winter, and maximum levels of Pb (0.82 μg g -1 dry wt.) were detected in Ulva sp. during summer. Legislative and health safety aspects were evaluated for Cd and Pb

Seaweed have a great capacity to accumulate heavy metals in their tissues. The chemical characterization of seaweed is important due to their use in environmental monitoring and human or animal food. The aim of the present study was to evaluate the multi-elemental composition of seaweed from San Jorge Gulf (Patagonia, Argentina) by Total Reflection X-ray Fluorescence (TXRF). The elements As, Br, Cu, Cr, Fe, Mn, Ni, Pb, Rb, Sr, V and Zn were seasonally analyzed and quantified in blades of Macrocystis pyrifera. TXRF showed to be a suitable technique for simultaneous multi-element analysis in this kind of samples. The results revealed seasonal variations in the chemical content for some elements; arsenic content was maximum in summer and autumn, iron concentration increased to the winter and zinc concentration was maximum in autumn. The sum of principal micronutrients (Fe + Zn + Mn + Cu) varied between 114 and 171 mg k- 1 g dw. The total As concentration ranged between 36 and 66 mg kg- 1. Lead, nickel and copper were not detected.

Full Text Available El objetivo de este trabajo fue evaluar la técnica electrocinética para la remediación de suelos contaminados con mercurio de la mina El Alacrán, ubicada en la cuenca del río San Jorge en el departamento de Córdoba, Colombia. Soluciones de KI y NaCl fueron usadas como agentes complejantes para la remoción del mercurio en dos concentraciones 0.01 y 0.05 M, aplicando voltajes de 30 y 40 V respectivamente. Los mejores resultados fueron obtenidos cuando el KI se usó como agente complejante, alcanzando porcentajes de recuperación hasta de 98.7%. los tratamientos donde el NaCl se usó como agente complejante no alcanzaron recuperaciones significativas (< 1%, excepto cuando se usó una concentración de 0.05 M de NaCl con un voltaje de 40 V alcanzando una recuperación de 38%. En todos los experimentos, el mercurio se movió hacia el ánodo, debido a la formación de complejos de naturaleza aniónica y se observó que incrementando la concentración y el voltaje, una mayor eficiencia y velocidad de remoción de mercurio del suelo fue alcanzada. Los resultados muestran que el ioduro tiene propiedades que lo hacen una solución electrolítica prometedora para la remoción del mercurio en suelos contaminados.

In the future the uranium exploration activities of CNEA would tend to improve the knowledge of geology and uranium favorability; to perform prospection tasks, and research and development in exploration technologies, to contribute to be in a position to meet the requirements of the country in the long term. On the other hand, a strong growth of nuclear capacity is expected in the first two decades of the next century. Based on its promising grade, the Cerro Solo uranium ore deposit was selected in 1990 by the CNEA to carry out an assessment project. The intensive exploration level was accomplished, as follows: definition of general characteristics of the main orebodies; detailed geologic studies; estimation of resources with adequate data; and preliminary selection of mining-milling methods to estimate the potential profitability of the project. The deposit belongs to the sandstone type. The mineralized layers are distributed into the fluvial sandstones and conglomerates of the cretaceous Chubut Group, lying 50 to 130 m deep Resources of the deposit, with an average grade of 0.3% U, in tonnes of recoverable uranium at costs of up to $80/kg U, are: Reasonable Assured Resources (RAR): 800 t U, Estimated Additional Resources, Category I (EAR-I): 2100 t U. Follow-up drilling programmes are being performed at present in some of the target sites defined in the paleochannel that hosts the Cerro Solo deposit, in order to establish the hypothetical resources of the area. The sites were determined as a result of the exploration that CNEA conducted in the Pichinan uranium district. Recently a regional research project was formulated, for the detailed exploration in the San Jorge Gulf Basin, where the Chubut Group is distributed. 17 refs, 4 figs

An extensive series of high-resolution satellite images from the advanced very high-resolution radiometer (AVHRR) and the sea-viewing wide field-of-view sensor (SeaWIFS) was used in a synoptic oceanographic characterization of San Jorge Gulf (SJG, Argentine Patagonia), an area of great significance for marine conservation and commercial fishing. Remotely sensed information was combined with on-board observer's data and published information to investigate the role of distinctive oceanographic features in relation to the life cycle of the Patagonian red shrimp (Pleoticus muelleri), main target of the industrial fleet in SJG. Three frontal systems-North, South and Outer SJG-are characterized. The North and South SJG fronts are associated with shrimp reproductive aggregations during late spring and summer. While both function as spawning/nursery grounds, they differ from each other in many respects. The thermohaline South SJG front has its maximum expression during the winter, reflecting the influence of the low-salinity Magellanic Plume, while the thermal North SJG front develops during spring and summer as the water column becomes stratified in the central basin of the gulf. Wind-related down-welling inshore of the front prevails in the North SJG, and upwelling in the South SJG frontal area. Chlorophyll a is concentrated near the thermocline on the stratified side of the North SJG, and for that reason, it is not detected by remote sensors during the spring bloom and the summer but becomes apparent offshore from the location of the front when the thermocline deepens during the fall (May). In the South SJG front, Chl-a concentration is apparent inshore from the front all year-round, related in part to upwelling-mediated resuspension. The northern end of the outer front coincides in time and space with a recurrent non-reproductive aggregation of red shrimp between November and January and is presumably related to foraging. It is argued that keeping the North and South

Little Ice Age advance and retreat of Glaciar Jorge Montt, Chilean Patagonia

A. Rivera

2012-03-01

Full Text Available Glaciar Jorge Montt (48°20' S/73°30' W, one of the main tidewater glaciers of the Southern Patagonian Icefield (SPI, has experienced the greatest terminal retreat observed in Patagonia during the past century, with a recession of 19.5 km between 1898 and 2011. This retreat has revealed trees laying subglacially until 2003. These trees were dated using radiocarbon, yielding burial ages between 460 and 250 cal yrs BP. The presence of old growth forest during those dates indicates that Glaciar Jorge Montt was upvalley of its present position before the commonly recognized Little Ice Age (LIA period in Patagonia. The post-LIA retreat was most likely triggered by climatically induced changes during the 20th century; however, Glaciar Jorge Montt has responded more dramatically than its neighbours. The retreat of Jorge Montt opened a 19.5 km long fjord since 1898, which reaches depths in excess of 390 m. The bathymetry is well correlated with glacier retreat rates, suggesting that dynamic responses of the glacier are at least partially connected to near buoyancy conditions at the ice front, resulting in high calving fluxes, accelerating thinning rates and rapid ice velocities.

Full Text Available El objetivo central de este trabajo es analizar el perfil sociodemográfico de los trabajadores transfronterizos o commuters de las ciudades de Tijuana-San Diego y Mexicali- Calexico de acuerdo con el sexo y el lugar donde se encuentra el trabajo. Los trabajadores transfronterizos o commuters son los individuos que residen en alguna ciudad de la frontera norte de México, pero cotidianamente cruzan la línea fronteriza para trabajar en la ciudad estadounidense contigua. La información que se utiliza para realizar este estudio es la obtenida por el Censo de Población y Vivienda mexicano del año 2010; sin embargo, el análisis sobre el perfil de los commuters se complementa con información de carácter etnográfico producto de diversas entrevistas realizadas a los trabajadores transfronterizos, principalmente en las ciudades de Tijuana y Mexicali. Consideramos que esta población tiene una imagen individual y cotidiana más completa de la compleja relación que se da en la frontera México-Estados Unidos, dada su característica principal de interacción continua entre ambos lados de la frontera. Ello al mismo tiempo nos permite contar con una visión más profunda de una realidad fronteriza que se basa en la dependencia creada y recreada en las sociedades tanto mexicana como estadounidense.

A ascese da Imagem Poética no encontro Jorge de Lima e Murilo Mendes

Full Text Available A partir do encontro de Murilo Mendes, Jorge de Lima e Ismael Nery e a conseqüente criação do livro de poemas Tempo e Eternidade, de 1935, após a morte do último, em 1930, os poetas Murilo e Jorge recriam sua voz poética na Restauração da poesia em Cristo. Num crescente questionamento do lugar do poeta na caótica modernidade, bem como na crença deste lugar como de ascese espiritual e recriação da imagem no plano onírico, os poetas aqui analisados nutriram sua trajetória com um surrealismo particular. A afinidade eletiva dos três artistas e sua aproximação com as artes plásticas podem ser apreciadas na linguagem tornada imagem, bem como na imagem tornada linguagem, como é o caso das séries de fotomontagens de Jorge de Lima aqui analisadas. Num procedimento tipicamente surrealista, Jorge de Lima apresenta imagens do inconsciente permeadas de poesia, onde ecoa a filosofia essencialista e visionária do poeta e pintor Ismael Nery, tantas vezes reivindicada por Murilo Mendes. Trata-se da abstração do tempo e do espaço, temas recorrentes em Jorge e Murilo, bem como a errância do homem e os atos do Cristo, a força da matéria e do erotismo, o equilíbrio entre as leis físicas e morais, o essencial, o absoluto e a unidade.

Evaluar la presencia de metales pesados: plomo(Pb, cobre (Cu, cadmio (Cd y mercurio (Hg en hígado y músculo pectoral derecho de bovino, procedentes de fincas de la zona del Sinú y San Jorge. Materiales y métodos. Se muestrearon bovinos machos, adultos, de raza cebú mestizo, entre 2 a 7 años los cuales fueron sacrificados para consumo humano durante seis meses. Las muestras se analizaron mediante: espectroscopia de absorción atómica, empleando lámparas de cátodo hueco y un quemador de aire acetileno para determinar Cu; vapor frío para la detección de Hg y polarografía para la detección de Cd y Pb. Resultados. Se observó que Los rangos de Hg, Cu, Cd y Pb estaban por debajo de los parámetros de referencia de la Comisión Europea y la Norma Oficial Mexicana. En el 4% de las muestras se encontraron niveles de Cu no permisibles para consumo humano. Conclusiones. La industria cárnica de la región presenta una gran potencialidad para acceder a mercados internacionales, debido a que el 96% de las reses presentaron niveles de metales por debajo de los límites permisibles de México y Europa. A pesar de que los niveles de mercurio se encuentran en los límites permisibles, la evaluación del riesgo basado en el índice de peligrosidad, sugiere que el consumo diario de 100 gramos de productos cárnicos con niveles de 0.08 ppm, podría incrementar el riesgo de envenenamiento a una persona de 70Kg.

Hydrotherapy and medical entrepreneurship: the "water spell" of Ricardo Jorge.

Science.gov (United States)

Pinto Costa, Rui Manuel

Between 1886 and 1893, the doctor and hygienist Ricardo Jorge was linked to a commercial and medical project on the waters of Gerês. Known for many centuries and used for therapeutic purposes, they were administered on an empirical basis. When new chemical analyses were first published, the empirical properties of these waters took on a new role in hydrotherapy based on their now proven mineral and medicinal qualities. The article discusses in detail Ricardo Jorge's business venture, framing it in the context of the economic collection and treatment potential of mineral waters and the revival of the phenomenon of hydrotherapy, legitimized by new developments in the chemical analysis of waters. The commercial failure to exploit the water resources highlights the difficulties of this project and the complexity of the professional practice of hydrological medicine, although it resulted in a strengthening of Ricardo's authority and prestige in the field of hydrotherapy.

Full Text Available Desde principios de la década de los 80, el sensor AVHRR a bordo de los satélites NOAA ha provisto de estimaciones de la temperatura de la superficie del mar (TSM a la comunidad científica en general. Hacia finales de la década de los 90, surge una nueva generación de radiómetros que combinan una mayor gama de mediciones espectrales con mejoras en la tecnología, como lo es el sensor  MODIS a bordo de los satélites Terra y Aqua. El desarrollo de este último sensor se basó en los años de trayectoria de la serie NOAA/AVHRR. La comprensión de la relación entre los productos derivados de distintos sensores es fundamental para el seguimiento continuo a largo plazo de cualquier variable y de la construcción de serie de tiempos combinados. El objetivo del presente trabajo fue realizar una comparación de los valores mensuales de TSM para el período 2003-2006 calculadas a partir de datos de la serie NOAA/AVHRR vs Aqua/MODIS sobre un sector de la Plataforma Continental Argentina frente al Golfo San Jorge. El análisis de las isotermas muestra un patrón de distribución similar durante todos los meses para ambos sensores. El coeficiente de correlación de Pearson tanto en el análisis estacional como mensual fue alto (> 0,8. El análisis comparativo de la temperatura medida en ambos sensores muestra que los productos de TSM son similares, teniendo en cuenta que la diferencia media de temperatura entre ambos sensores es inferior a 0,5ºC. Por lo tanto, para el estudio de largas series de tiempo de TSM en la plataforma continental argentina se puede utilizar en forma continua las mediciones de Aqua/MODIS, cuando ya no se disponen las de NOAA/AVHRR.

Inherited discontinuities and fault kinematics of a multiphase, non-colinear extensional setting: Subsurface observations from the South Flank of the Golfo San Jorge basin, Patagonia

We use three-dimensional (3D) seismic reflection data to analyze the structural style, fault kinematics and growth fault mechanisms of non-colinear normal fault systems in the South Flank of the Golfo San Jorge basin, central Patagonia. Pre-existing structural fabrics in the basement of the South Flank show NW-SE and NE-SW oriented faults. They control the location and geometry of wedge-shaped half grabens from the "main synrift phase" infilled with Middle Jurassic volcanic-volcaniclastic rocks and lacustrine units of Late Jurassic to Early Cretaceous age. The NE-striking, basement-involved normal faults resulted in the rapid establishment of fault lenght, followed by gradual increasing in displacement, and minor reactivation during subsequent extensional phases; NW-striking normal faults are characterized by fault segments that propagated laterally during the "main rifting phase", being subsequently reactivated during succesive extensional phases. The Aptian-Campanian Chubut Group is a continental succession up to 4 km thick associated to the "second rifting stage", characterized by propagation and linkage of W-E to WNW-ESE fault segments that increase their lenght and displacement in several extensional phases, recognized by detailed measurement of current throw distribution of selected seismic horizons along fault surfaces. Strain is distributed in an array of sub-parallel normal faults oriented normal to the extension direction. A Late Cretaceous-Paleogene (pre-late Eocene) extensional event is characterized by high-angle, NNW-SSE to NNE-SSW grabens coeval with intraplate alkali basaltic volcanism, evidencing clockwise rotation of the stress field following a ∼W-E extension direction. We demonstrate differences in growth fault mechanisms of non-colinear fault populations, and highlight the importance of follow a systematic approach to the analysis of fault geometry and throw distribution in a fault network, in order to understand temporal-spatial variations

(Palabras del doctor Guillermo Rueda Montaña, durante el entierro del doctor Jorge Cavelier, el 25 de junio de 1978.

Señores:

Cuentan viejos relatos indígenas, de la "Tierra de los árboles inmensos", que en los grandes bosques se produce un silencio total de muchas horas, cuando cae uno de esos titanes. Varias veces centenario. Como si la tierra y todas sus criaturas recibieran el impacto y el profundo dolor de la caída de un ser aparentemente inmortal. Así nosotros, absortos y asombrados, presenciamos el derrumbe de este otro gigante que proyectó su sombra sobre el Territorio Nacional, y se constituyó por sus ejecutorias, en figura casi mística en la Medicina Colombiana.

Pues fue JORGE CAVELIER el hombre - acción. Si hubiera vivido en el Egipto clásico, habría construído una pirámide, si en los tiempos medioevales, habría emprendido una cruzada o levantado una Catedral.
Tenía una visión muy clara y era capaz de traducirla a fuerza de mandobles si fuere necesario, en una obra de interés común.
La hercúlea conformación de su raza, mezcla de celtas y vikingos, creadora de marinos, de hombres de acción, de grandes capitanes, lo impulsaba a la ejecución.
Cuando se fijaba una meta, siempre orientada hacia el progreso de la comunidad, se lanzaba en procura sin que ningún obstáculo pudiera detener el impulso emocional de su voluntad ejecutiva. Así también, con esa misma garra, se enfrentó a la muerte, a rompe y rasga, sin cuartel, sin concesiones, porque quería vivir, para continuar haciendo.

Esos ojos profundamente azules, que en tantas ocasiones reflejaron la ira, cuando algo o alguien se interponía en el camino de su férrea voluntad, eran también capaces de brillar emocionados cuando se tocaba sus más íntimas fibras de aguda sensibilidad social y
completa solidaridad humana.
Fué intemperante y fue soberbio, pero fue grande en sus prop

Analía Verónica Uhrich

Full Text Available Objetivos: Investigar especies de Ulva del Golfo San Jorge, Patagonia Argentina, integrando aspectos bioquímicos, actividad biológica y variaciones estacionales/habitacionales que permitan determinar su potencial aplicación en Salud. Métodos: Las algas se colectaron estacionalmente en playas con y sin contaminación antrópica; se secaron, molieron y extrajeron con etanol. Los extractos se fraccionaron mediante solventes de distinta polaridad. Cada fracción fue caracterizada mediante reacciones químicas cualitativas y cromatografía. Las fracciones ricas en flavonoides se analizaron por HPLC-DAD y los lípidos, por TLC. La actividad biológica se ensayó mediante el test de citotoxicidad de Artemia salina, inhibición de la elongación radicular, inhibición de la xantino oxidasa, actividad antioxidante y antibacteriana. Resultados: Se identificaron Ulva rigida y Ulva lactuca. Ambas evidenciaron flavonoides, taninos, quinonas, lípidos, carbohidratos, esteroides. Los flavonoides resultaron mayoritarios en U. rigida (otoño e invierno y en U. lactuca (primavera e invierno, destacándose kayaflavona. Se detectaron alcaloides en Ulva rigida (verano. Los lípidos fueron mayoritarios en verano; U. lactuca en invierno mostró monogalactosildiacilglicérido y en otoño, digalactosilacilglicérido y fosfatidilcolina. La actividad inhibitoria de la elongación radicular, que presume actividad antitumoral, fue importante y dosis dependiente, destacándose U. rigida de otoño y primavera (DE50= 480 y 520 µg/ml, respectivamente. Las demás bioactividades resultaron escasas o negativas. Conclusiones: Las variaciones metabólicas observadas muestran la importancia de considerar las condiciones espacio - temporales al planificar una colecta de ejemplares para su estudio y/o aplicación. Este primer análisis integral de especies de Ulva de la Patagonia Argentina, evidencia su potencialidad como antitumoral.

Full Text Available O objetivo neste trabalho foi avaliar a qualidade da carne do músculo longissimus thoracis de bovinos durante a maturação. Amostras de 22 bovinos Nelore e 22 Red Norte machos, com 24 meses de idade, foram coletadas às 24 horas post mortem, mantidas a 2oC e analisadas aos 1, 7, 14 e 21 dias. Os animais foram terminados em confinamento (112 dias com silagem de milho (50% e concentrado (50% à vontade. Os valores de pH final, perda por cocção, umidade, proteína, gordura e cinzas foram semelhantes entre as amostras de animais Nelore e Red Norte. O teor de vermelho (a* e a intensidade de amarelo (b* foram semelhantes entre as carnes dos dois grupos genéticos, porém a luminosidade (L* foi maior nas amostras de animais Red Norte. A maturação afetou significativamente a luminosidade, o teor de vermelho e amarelo, croma (C*, o ângulo de tonalidade (H* e a percepção subjetiva da cor (ΔE, de forma que as alterações de cor mais importantes ocorreram entre 7 e 14 dias. A força de cisalhamento na carne dos animais Red Norte foi cerca de 0.9 kg inferior às dos animais Nelore. A maturação influenciou a força de cisalhamento ao longo da maturação e determinou reduções de 1,09; 0,21 e 0,56 kg nos períodos de 1 a 7; 7 a 14 e 14 a 21 dias, respectivamente. O índice de fragmentação miofibrilar foi maior na carne dos animais Red Norte e nas amostras maturadas por 21 dias. A carne dos animais Red Norte apresentou maior luminosidade e maciez. A maturação melhora a maciez das carnes, por reduzir a força de cisalhamento, porém modifica a cor, cujas alterações mais importantes acontecem entre 7 e 14 dias. A escolha do tempo de maturação mais adequado para as carnes bovinas depende do atributo a ser valorizado.The objective in this study was to evaluate meat quality of longissimus thoracisi muscle during ageing.

Full Text Available O presente artigo tem por fito analisar a estrutura temporal do conto “Testemunha”, de Lídia Jorge, a partir da aplicação teórica da metodologia do estudo do texto narrativo proposto por Gérard Genette, mas se apropriando também de outros teóricos que estudaram o assunto: Paul Ricoeur e Benedito Nunes. O conto em questão permite esse tipo de abordagem, pelo fato da escritora se valer do tempo narrativo como categoria central em sua história, apresentando evocações de cenas da infância, no período escolar, rememoradas pela protagonista. A alteração da ordem temporal (anacronia é, portanto, evidente nesta narrativa, tendo a organização discursiva subvertida por meio de recuos temporais (analepses, que contribuem para a motivação da história.

As legendas dos Santos Jorge da Capadócia e Cipriano de Antioquia: relíquias da controvérsia arriana (325-381 d.C.

Full Text Available O historiador inglês Edward Gibbon, em seu clássico A história do declínio e queda do Império Romano, provocou certa discussão no interior da academia inglesa do final do século XIX ao afirmar que o mártir, santo e herói cristão Jorge da Inglaterra devia ser identificado com Jorge da Capadócia, bispo de Alexandria entre 356 e 361 d.C., ano de sua morte por linchamento. Jorge foi vítima da “controvérsia arriana”, uma disputa teológica sobre a natureza de Cristo que acirrou os ânimos de orientações doutrinárias adversárias: para os “arrianos”, como Jorge e o então imperador Constâncio, Cristo era uma criatura, por meio de quem o Pai fez as outras criaturas existirem; para os “trinitaristas”, como Atanásio de Alexandria, o Filho era partícipe de uma Trindade, três “realidades subsistentes” (hypostaseis de uma mesma substância (homoousios, “consubstancial”. Desenvolvo, neste trabalho, uma solução que concilia a hipótese de Gibbon àquela de seus críticos, segundo quem o nome Jorge já estava associado a um santo mártir anterior à emergência histórica do bispo arriano. Com base em outra legenda, tão antiga quanto a de são Jorge – a dos santos Cipriano e Justina de Antioquia – apresento evidências de que, durante a controvérsia do século IV, a tradição hagiográfica do “santo-bruxo” da Síria foi apropriada não apenas pelo partido arriano, tal qual fizeram com a legenda de são Jorge da Capadócia, mas também pelos adversários trinitaristas. A chave para a conexão entre os documentos e a propaganda partidária é o “feiticeiro Atanásio”, personagem que é citado em determinadas versões das duas legendas. A despeito de ter existido um santo mártir homônimo, como quiseram os críticos de Gibbon, concluímos que, são Jorge da Capadócia pode, de fato, ser identificado, a partir da segunda metade do século IV, com o bispo arriano.

Se cumple el centenario del nacimiento del profesor Jorge Enrique Cavelier, a quien tanto debe la ciencia colombiana en su polifacética actividad médica, docente y de creador e impulsor de instituciones médicas y de salud pública.

En el hogar formado por el ingeniero francés Germán Cavelier, nacido en Normandía y quien vino a nuestro país a laborar en los trabajos del canal de Panamá y de la dama cartagenera doña Cristina Jiménez, Jorge E. Cavelier, nació el 12 de agosto de 1895, el que al paso de los años sería figura prestante de la medicina colombiana.

De su padre, heredó la severa dignidad de la perseverante consagración al trabajo emblema de su estirpe. Atemperada por la bondad que demostró a los enfermos, en la carrera médica que por la suave influencia materna habría de seguir y en la que descolló siempre.

El doctor Cavelier, luego de graduarse en la Universidad nacional en 1921, siguió estudios de especialización en clínica quirúrgica y urología en la Universidad de Chicago. Se recuerda que al regresar al país fue el primero en traer y aplicar la insulina recientemente descubierta para tratar la diabetes.

Sus servicios a la salud pública abarcaron desde la fundación del Instituto de Higiene de Cundinamarca, su admirable labor como Director de Higiene de Bogotá (1946-48, donde inició la descentralización de este importante organismo creando los primeros Puestos y Centros de Salud~y Ministro de Higiene (1949-50, en que implantó la medicatura rural y los Primeros Planes Nacionales (de Salubridad y Hospitalario, base del progreso y mejoramiento de la salud pública en Colombia.

E-mail: ummaia@usp.br This study aimed to assess the current status of stingless bee beekeeping (meliponiculture in the State of Rio Grande do Norte, Brazil, with the aid of structured questionnaires made during visits to beekeepers. The results were compared with a previous census made in the state and with a similar study from Australia. Meliponiculture in Rio Grande do Norte is still informal and little standardized. The activity has grown in recent years considering the mean number of nests per beekeeper. Most apiaries are formed of up to 50 colonies, usually distributed in the backyards of homes. Twelve species of stingless bees were reared in the state, and the most common was the “Jandaíra” bee (Melipona subnitida, whose honey is considered medicinal. While many beekeepers already know the importance of bees as pollinators, stingless bees are still not used for crop pollination. Compared to a recent analysis of beekeeping in Australia, meliponiculture in Brazil is more traditional, honey is the main product and the number of colonies per beekeeper is much higher. Our results highlight the need to reinforce knowledge about bees and promote specific training aimed at improving and standardizing management practices.

Classification of Nortes in the Gulf of Mexico derived from wave energy maps

Science.gov (United States)

Appendini, C. M.; Hernández-Lasheras, J.

2016-02-01

Extreme wave climate in the Gulf of Mexico is determined by tropical cyclones and winds from the Central American Cold Surges, locally referred to as Nortes. While hurricanes can have catastrophic effects, extreme waves and storm surge from Nortes occur several times a year, and thus have greater impacts on human activities along the Mexican coast of the Gulf of Mexico. Despite the constant impacts from Nortes, there is no available classification that relates their characteristics (e.g. pressure gradients, wind speed), to the associated coastal impacts. This work presents a first approximation to characterize and classify Nortes, which is based on the assumption that the derived wave energy synthetizes information (i.e. wind intensity, direction and duration) of individual Norte events as they pass through the Gulf of Mexico. First, we developed an index to identify Nortes based on surface pressure differences of two locations. To validate the methodology we compared the events identified with other studies and available Nortes logs. Afterwards, we detected Nortes from the 1986/1987, 2008/2009 and 2009/2010 seasons and used their corresponding wind fields to derive the wave energy maps using a numerical wave model. We used the energy maps to classify the events into groups using manual (visual) and automatic classifications (principal component analysis and k-means). The manual classification identified 3 types of Nortes and the automatic classification identified 5, although 3 of them had a high degree of similarity. The principal component analysis indicated that all events have similar characteristics, as few components are necessary to explain almost all of the variance. The classification from the k-means indicated that 81% of analyzed Nortes affect the southeastern Gulf of Mexico, while a smaller percentage affects the northern Gulf of Mexico and even less affect the western Caribbean.

The possibilities to stablish an organization of plowmen were studied in the northern zone of the Department del Cauca (Colombia in 1993. This research was carried out in four representative subzones, San Antonio, Mondomo, El Pital and Pescador. The factors included in the study were: the regional pattern of mechanization (PMR, draught offer, economical analysis and animal management. At the same time, a survey between the plowmen supplied information about feeding, health, criteria for the selection of draught animals, machines and implements, monthly income and regional pattern of mechanization (PMR. As a result, the Regional Organization of Plowmen of the Northern Cauca was created. The draught offer in the zone (number of oxen and plowmen was concentrated (more than 80% in the subzones of Pescador and Mondomo. San Antonio and El Pital were the most profitable subzones, The survey revealed a necessity for the education of plowmen and a supplementary action to diet and sanitary care of the oxen because it is difficult to define a feeding rule with reference to the energy requirements.

1983-01-01

The Colorado Geological Survey initiated and carried out a fully integrated assessment program of the geothermal resource potential of the western San Luis Valley during 1979 and 1980. The San Luis Valley is a large intermontane basin located in southcentral Colorado. While thermal springs and wells are found throughout the Valley, the only thermal waters found along the western part of the Valley are found at Shaw Warm Springs which is a relatively unused spring located approximately 6 miles (9.66 km) north of Del Norte, Colorado. The waters at Shaws Warm Spring have a temperature of 86 F (30 C), a discharge of 40 gallons per minute and contain approximately 408 mg/l of total dissolved solids. The assessment program carried out din the western San Luis Valley consisted of: soil mercury geochemical surveys; geothermal gradient drilling; and dipole-dipole electrical resistivity traverses, Schlumberger soundings, Audio-magnetotelluric surveys, telluric surveys, and time-domain electro-magnetic soundings and seismic surveys. Shaw Warm Springs appears to be the only source of thermal waters along the western side of the Valley. From the various investigations conducted the springs appear to be fault controlled and is very limited in extent. Based on best evidence presently available estimates are presented on the size and extent of Shaw Warm Springs thermal system. It is estimated that this could have an areal extent of 0.63 sq. miles (1.62 sq. km) and contain 0.0148 Q's of heat energy.

Restless Gentleman: Jorge Isaacs in Nineteenth-Century Colombia

Full Text Available María (1867 is one of the most widely read Spanish-American novels of all times; this work compares it to the ups and downs in its author's life. Jorge Isaacs had been rich and fallen on hard times; had been a conservative Catholic and turned into an anti-clerical liberal; had been a merchant and rose up in arms; later he was exiled from his native province. The parable of his life deserves an explanation and this paper offers two clues: Isaacs' ineptitude for business and the high price he had to pay for changing his political-ideological sign into one that ten years later opposed the political regime of La Regeneración (1878-1900. Ironically, a later conservative regime (1900-1930 crafted the literary canonization of María, a nostalgic and sentimental novel, and established it as a national model of immutable private morality.

Weak polygyny in California sea lions and the potential for alternative mating tactics.

Directory of Open Access Journals (Sweden)

Ramona Flatz

Full Text Available Female aggregation and male territoriality are considered to be hallmarks of polygynous mating systems. The development of genetic parentage assignment has called into question the accuracy of behavioral traits in predicting true mating systems. In this study we use 14 microsatellite markers to explore the mating system of one of the most behaviorally polygynous species, the California sea lion (Zalophus californianus. We sampled a total of 158 female-pup pairs and 99 territorial males across two breeding rookeries (San Jorge and Los Islotes in the Gulf of California, Mexico. Fathers could be identified for 30% of pups sampled at San Jorge across three breeding seasons and 15% of sampled pups at Los Islotes across two breeding seasons. Analysis of paternal relatedness between the pups for which no fathers were identified (sampled over four breeding seasons at San Jorge and two at Los Islotes revealed that few pups were likely to share a father. Thirty-one percent of the sampled males on San Jorge and 15% of the sampled males on Los Islotes were assigned at least one paternity. With one exception, no male was identified as the father of more than two pups. Furthermore, at Los Islotes rookery there were significantly fewer pups assigned paternity than expected given the pool of sampled males (p<0.0001. Overall, we found considerably lower variation in male reproductive success than expected in a species that exhibits behavior associated with strongly polygynous mating. Low variation in male reproductive success may result from heightened mobility among receptive females in the Gulf of California, which reduces the ability of males to monopolize groups of females. Our results raise important questions regarding the adaptive role of territoriality and the potential for alternative mating tactics in this species.

Thus, she devises a secret plan, which includes losing her virginity to a complete stranger, shortly before committing the crime, so she could argue that her boss had raped her and that she killed him in self-defense. Firstly, the text shows the contrast between formal justice and taking justice into own hands. Secondly, the question of self-inflicted punishment, which in the story takes place before the perpetration of the crime. Finally, the issue whether truth is the version that can be inferred from the evidence presented in a trial, or the one which is kept to themselves by those involved in a crime. Emma Zunz, de Jorge Luis Borges, es la historia de una chica que decide matar a su jefe para vengar la muerte de su padre, creyendo que la versión de su padre de un hecho que ocurrió años atrás era cierta. De este modo, diseña un plan secreto, que incluye la pérdida de su virginidad con un desconocido, poco antes de cometer el crimen, para poder argumentar que su jefe la había violado y que ella lo mató en defensa propia. En primer lugar, el texto muestra el contraste entre la justicia formal y la justicia por cuenta propia. En segundo lugar, la cuestión de la pena infligida a uno mismo, lo que en la historia se produce antes de la comisión del delito. Por último, la cuestión de si la verdad es la versión que se puede inferir de las pruebas presentadas en un juicio, o la que se guardan para sí mismas las personas involucradas en un crimen.

Jorge Oteiza's Modernity and His Latin American Travels

Directory of Open Access Journals (Sweden)

Marina Pérez de Mendiola

2006-01-01

Full Text Available Along with Eduardo Chillida, Jorge Oteiza is one of the best-known Basque sculptors of his generation. Although many scholars have written on Oteiza's significant contribution to the field of sculpture, and have analyzed his theories on the meaning of art, very few take into consideration Oteiza's 13 years in Latin America, much less acknowledge that these years had a decisive impact on his art and particularly on his critical essays and poetry. In this essay, I explore how Oteiza's stay in Latin America contributed to his reevaluation of the avant-garde movements in Europe and Latin America, and how it led him to redefine his relationship to progress, science, reason and nature, space and time, ethics, and national art. During the course of his interaction with Latin American artistic movements, Oteiza's thoughts on artistic singularity and universality matured, and he confirmed his strong sense of spirituality in order to liberate traditionally defined conceptual opposites such as the intellectual and the sacred from their teleological confinement.

Art and aesthetics in the Minutogramas of Jorge Oteiza

Directory of Open Access Journals (Sweden)

José Javier Azanza López

2018-02-01

Full Text Available During his stay in Buenos Aires in 1939, Jorge Oteiza promoted the artistic information service The art walk, a consequence of which are his Minutogramas. They are close to the comic aesthetic, show a remarkable interest in graphic design, and display a discourse that echoes Surrealism and the “ramonismo” of Ramón Gómez de la Serna. In this way, the sculptor provides some keys to understanding his aesthetic thinking: his belief in the universal values of Geometry following in the footsteps of Leonardo; Nature as the foundation for sculptural creation which he discovers in Maillol, Zadkine, Alberto and Erzia; his admiration for El Greco, Velázquez and Goya as Hispanic models; the recognition of Cézanne as the father of Contemporary Art and the teachings of Hans Arp, constitute some of the themes found in his Minutogramas, in which he also manifests his humanistic dimension in several areas of knowledge.

Full Text Available Lychee crops occurs mainly in South and Southeast regions of Brazil. In this study, the digital terrain modeling (DTM of the micro-region Mata Norte Pernambucana, was designed to identify the districts that have potential for lychee crop, through the parameters of average altitude, precipitation and temperature. The districts analyzed were Aliança, Buenos Aires, Camutanga, Carpina, Condado, Ferreiros, Goiâna, Itambé, Itaquitinga, Lagoa do Carro, Lagoa do Itaenga, Macaparana, Nazaré da Mata, Paudalho, Timbaúba, Tracunhaém and Vicência. The analysis of climate, wind power and altitude in Mata Norte Pernambucana, has revealed that some districts of the micro-region have potential for lychee crops, which is a product with great financial return, and may contribute to increase economy and quality of life in the micro-region.

Detrital zircon geochronology and provenance of the Chubut Group in the northeast of Patagonia, Argentina

Science.gov (United States)

Navarro, Edgardo L.; Astini, Ricardo A.; Belousova, Elena; Guler, M. Verónica; Gehrels, George

2015-11-01

The Chubut Group constitutes the most widespread sedimentary unit in NE Patagonia, characterized by variable-energy fluvial deposits. U-Pb analysis of detrital zircons from two sections of the Chubut Group constraint the age of the oldest sedimentary rocks in the northeast of the Somuncurá - Cañadón Asfalto Basin. In the Cañadón Williams area, at San Jorge section, 20 km NW of Telsen locality, dating of 56 detrital zircons from a medium to coarse sandstone indicated a maximum depositional age of 109 ± 1 Ma (n = 4). These sandstones were interpreted to represent shallow channels, associated with a lacustrine system. In the Telsen locality, a laser ablation analysis of 115 detrital zircons from a medium to coarse-grained sandstone, from fluvial channel facies, yielded a maximum depositional age of ca. 106 ± 1 Ma (n = 8). Both ages are consistent with volcanic events of the Barremian to Albian age in the central Patagonian Andes Region. Cathodoluminescence images of zircons from the San Jorge sample suggest an igneous origin, which is further supported by Th/U values above 0.5 in most of the grains. The distribution of the statistical modes of the main age populations of detrital zircons for the two samples [182, 185 and 189 Ma for Telsen sample (T2S) and 181 ± 1 Ma for San Jorge sample (SJS)] matches the age of the volcanic Marifil Formation. The rocks of the Marifil Formation of these ages are exposed NE to SE of the study area. The abundance of zircons of similar Jurassic ages (n = 52 for SJS and n = 105 for T2S) and the external morphology of the zircons in the sample SJS, implies a close proximity of the source area. Suggestion that the Marifil Formation was the main provenance source is also supported by northeast-southeasterly paleocurrents measured at the San Jorge and Telsen sections.

His reception therefore is mixed. For his English-language readers, he is a fascinating source of exotic and titillating narratives about the vast, unknown country of Brazil, and for Brazilians he is either a "great ambassador of Brazilian culture around the world" or a faux populist who disguises sexist and racist attitudes behind charming prose. This paper will address Amado's literary career, his unique contributions to Brazilian letters, the challenges of translating his work, and his influence on the production of a new Brazilian literature for export

In this work, a study on a set of paintings from the most significant altarpiece assigned to Master Jorge Afonso (c. 1470-1540) painting workshop is presented. This altarpiece is composed by fourteen paintings made to the church of Convento de Jesus, in Setúbal, Portugal, and was made circa 1517-19/1530, according to art-history. This set of paintings is compared to one of the other most important Portuguese altarpieces from the 16th century: the panels of the Round Church of the Convento de Cristo, in Tomar, made circa 1510-1515. The aim of this study is to characterize the wooden support, pigments, ground layers materials and technique used in Jorge Afonso workshop by means of complementary analyses. A dendrochronological approach was made in order to corroborate (or not) the historical date initially assigned. Infrared photography (IRP) and reflectography (IRR) allowed the study of the underdrawing technique and macro photography (MP) was used to recognize overlapping layers technique. Cross-sections from the paintings were examined by optical microscopy (OM), and analyzed by μ-X-ray diffraction (μ-XRD), Energy Dispersive X-ray Fluorescence spectroscopy (EDXRF), Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (SEM-EDS), micro-Raman spectroscopy (μ-Raman), micro-Fourier Transform Infrared spectroscopy (μ-FTIR), Pyrolysis Gas Chromatography Mass Spectrometry (py-GC/MS). The characterization of the palette and ground layers and the study of the overlapping of paint layers brought a new insight of the adopted painting techniques by the most important group of painters working in Portugal in the 16th century - the Lisbon workshop, leaded by Master Jorge Afonso.

Os mecanismos envolvidos na suscetibilidade/resistência do hospedeiro frente ao agente não estão ainda elucidados, dentre eles encontra-se a constituição genética. Portanto, o objetivo deste trabalho é avaliar a distribuição fenotípica do grupo sangüíneo Duffy em pacientes com doença de Jorge Lobo e calcular suas freqüências gênicas. Foram analisados 21 pacientes, 13 caucasóides e oito mestiços (tipo moreno claro, provenientes do estado do Acre, e 44 indivíduos, não acometidos por esta doença, habitantes da cidade de Rio Branco (AC, como grupo controle. O fenótipo Duffy foi definido pela presença dos antígenos nas hemácias pela reação de aglutinação dos eritrócitos com anti-soros anti-Fya e anti-Fyb incubando-se a 37ºC e aplicando-se o teste da antiglobulina humana. Os resultados mostram que a distribuição fenotípica do sistema Duffy nos pacientes difere significativamente daquela observada nos controles, pela alta freqüência de indivíduos com fenótipo Fy(a-b-. Observa-se claramente que os pacientes apresentam maior freqüência do alelo FY e menor do alelo FYA do que os controles. O alelo FYB (não inclui os alelos que não são expressos tem praticamente a mesma freqüência nos dois grupos. Com relação à comparação entre distribuição do grupo sangüíneo Duffy com as formas clínicas, sugere maior número de pacientes com forma localizada da doença de Jorge Lobo apresentando um predomínio do fenótipo Fy(a-b+ seguido do fenótipo Fy(a-b- e inexistência do fenótipo Fy(a+b-. Por outro lado, temos a forma disseminada com maior incidência de fenótipo Fy(a+b-. A forma multifocal foi menos expressiva.

Full Text Available The mesquite (Prosopis juliflora (Sw DC was established as a successful action of xerophilous introduction in Brazilian Northeast dry region. Its fruits are used in animal feed and the wood may be used as piles, firewood and charcoal. The species was introduced in 1942, spreading in "low areas" in Rio Grande do Norte, Paraiba, Pernambuco, Bahia and Piauí States. This article aims to elucidate how mesquite was introduced in Rio Grande do Norte State and to understand how it was spread. It was first introduced in Rio Grande do Norte State by the introduction experiments installed at São Miguel farm in the municipality of Angicos. The enthusiasm of technicians and researchers promoted the distribution of pods and seedlings on farms and cities in the state. In addition, there were government incentives to production, distribution and planting the species. This work aims to establish considerations to be used as historical basis on studies about this species and to consider aspects regarding current situation of this culture in Brazilian Northeast.

The five sheets of the San Francisco folio the Tamalpais, Ban Francisco, Concord, Ban Mateo, and Haywards sheets map a territory lying between latitude 37° 30' and 38° and longitude 122° and 122° 45'. Large parts of four of these sheets cover the waters of the Bay of San Francisco or of the adjacent Pacific Ocean. (See fig. 1.) Within the area mapped are the cities of San Francisco, Oakland, Berkeley, Alameda, Ban Rafael, and San Mateo, and many smaller towns and villages. These cities, which have a population aggregating about 750,000, together form the largest and most important center of commercial and industrial activity on the west coast of the United States. The natural advantages afforded by a great harbor, where the railways from the east meet the ships from all ports of the world, have determined the site of a flourishing cosmopolitan, commercial city on the shores of San Francisco Bay. The bay is encircled by hilly and mountainous country diversified by fertile valley lands and divides the territory mapped into two rather contrasted parts, the western part being again divided by the Golden Gate. It will therefore be convenient to sketch the geographic features under four headings (1) the area east of San Francisco Bay; (2) the San Francisco Peninsula; (3) the Marin Peninsula; (4) San Francisco Bay.

Fluid typing and tortuosity analysis with NMR-DE techniques in volcaniclastic reservoirs, Patagonia/Argentina

Alternative hydrocarbon-detection techniques are used to differentiate water from hydrocarbon where resistivity-based methods are difficult to apply, such as freshwater reservoirs and complex lithologies. One of these areas is represented by the complex volcaniclastic freshwater reservoirs in the Golfo San Jorge basin, Patagonia Argentina, where water and oil have often identical response on conventional logs. Some advances in hydrocarbon identification based on nuclear magnetic resonance (NMR) techniques were achieved in long T1 environments (very light oils, gas) in the Golfo San Jorge basin by previous NMR fluid typing methods. However, since medium to heavy oils are commonly present in these intervals, hydrocarbon detection by such techniques cannot be properly achieved. In addition, restricted diffusion phenomena recognized in these intervals, constitute further complications in fluid typing since its presence have similar response than native oil. To address this problem, a fluid characterization method using NMR Diffusion-Editing techniques and processing/interpretation with D-T2 maps in a suite of NMR measurements was applied. The technique allowed the detection and evaluation of restricted diffusion in these reservoirs, enabling better hydrocarbon characterization in a broad viscosity range (from light to heavy). The method also improved the petrophysical evaluation because restricted diffusion is related to tortuosity in the reservoir. Since the application of this innovative reservoir evaluation method, fluid prognosis vs well completion results was increased from around 68% to around 88% in Golfo San Jorge basin. Moreover, in some of these areas rates above 95% were recently achieved in 2004. (author)

Jorge Luis Borges at two final judgments

Full Text Available Em 1988, Beatriz Sarlo propõe uma passagem entre duas poéticas em Jorge Luis Borges: de Evaristo Carriego (1930 em direção a Historia universal de la infamia (1935. Os dois textos são “insidiosos”, defende a pesquisadora, porque falsificam as biografias de seus personagens. Porém, a coletânea de 1935 opera em âmbito universal. Este movimento, afirma Sarlo, é portador de um acumulo de prerrogativas, associado à dupla inscrição de Borges: o cidadão do mundo e, simultaneamente, o de um país pensado a partir de Buenos Aires. Neste ensaio, sugerimos uma passagem anterior, evidenciada em “Sentirse en muerte” (1928: do criollismo – o poeta dos arrabaldes, dotado da capacidade de transporte sensível e instalado nos limites de sua cidade imaginada, que busca a representação poética digna de seu conceito de argentinidade – em direção à prosa que alcança o caráter argumentativo-reflexivo dos ensaios sobre o tempo e a eternidade característicos de Borges, início de sua legitimação como “percibidor abstracto del mundo”. Este movimento é também portador de um acúmulo de prerrogativas, dupla inscrição de Borges: como poeta, literato e ensaísta programático do criollismo; como meditador dedicado aos assombros contidos em nossos conceitos de vida, tempo e universo, operador de textos da Filosofia e da Teologia.

El eje fecundatorio norte-sur del Perú: una interpretación psicológica

Directory of Open Access Journals (Sweden)

Federico R. León

1984-06-01

Full Text Available El eje fecundatorio norte-sur consiste en una relación ordinal entre una dimensión geográfica  (regiones de planificación Norte, Centro y Sur del Perú y el deseo de hijos de la mujer peruana, siendo el deseo mayor entre las norteñas y menor entre las sureñas. Análisis correlacionales, de covarianza, y de regresión fueron ejecutados en el banco de datos de la ENPA (N = 6,437 para determinar en las mujeres con hijos del norte, centro y sur (N = 1, 765 si variables tales como la altura/cultura (costa, sierra, urbanización, educación, ingreso, trabajo, conyugalidad, número de hijos vivos, y número de hijos muertos podrían dar cuenta del eje fecundatorio. El eje fecundatorio probó ser independiente de estas variables, aunque algunas interacciones aproximaron significación estadística. Se propuso una interpretación psicológica de  los resultados. La mujer norteña desearía más hijos debido a su mayor aceptación de un rol femenino dependiente y mayor disposición a satisfacer el machismo de su marido. La mujer sureña desearía menos hijos debido a su posición más autónoma en la vida familiar y mayores expectativas de participación activa en roles ocupacionales.

Full Text Available Reality shown by nature gives us multiple messages. These messages communicate continuously with each individual thereby establishing a strong person-nature link. This link can be represented and studied via an artistic or creative act. This study shows some of the multiple connections established between nature and people, including the aesthetic and metaphysical dimensions of reality. As a syncretic example of a process nature-reality, aesthetic-art and spirituality-transcendence, the case of the sculptor Jorge Oteiza is outstanding in terms both of his life and work. The author studies the conceptualization of his work, in a synthetic way, through its connection to significant life experiences (SLE with nature, expressed by his aesthetic thought and represented in his art.

Hitler na crônica militante de Jorge Amado

Directory of Open Access Journals (Sweden)

Márcio Henrique Muraca

2013-08-01

Full Text Available Militante comunista até meados da década de 1950, Jorge Amado configura sua obra com sopros panfletários. Escritor prolífero, seus escritos vão além dos romances, sendo o baiano um assíduo colaborador em jornais de seu tempo. Entre 1942 e 1945, Amado escreveu a colona “Hora da Guerra”, no jornal O Imparcial, de Salvador. Umas das figuras mais citadas e tratadas pelo autor é Adolf Hitler, sobretudo como metonímia do mal. A figuração demoníaca do líder alemão está articulada, no plano internacional, ao movimento comunista encabeçado por Moscou e, no plano nacional, ao engajamento esquerdista antifascista que enxerga no período da Guerra a oportunidade de virada democrática no Brasil. Em termos literários, a crônica de Amado estabelece uma dicção modernista da linguagem, enquanto ideologicamente pretende convencer pela emoção, ao associar Hitler a uma tríade: ódio-vingança-repúdio, tudo em oposição a uma identidade nacional baseada na miscigenação.

Tres tipos de cortes de secuencias de margen pasivo, geográficamente bien diferenciados, afloran en el norte de Cuba: A-Cortes de Guaniguanico, divisibles a su vez en tres subtipos: Sierra del Rosario, Sierra de los Órganos y Cinturón Cangre; B-Cortes del norte de Cuba Central, caracterizados por una manifiesta zonalidad estratigráfica y estructural, y C-Cortes de Maisí, caracterizados poe el metamorfismo de bajo grado de sus rocas. En estas tres regiones los cortes más jóvenes, comenzando en el Jurásico Superior, son casi exclusivamente carbonatados, mientras que su parte inferior (Oxfordiano y más antiguo es terrígena, exceptuando los más septentrionales, en Cuba central, donde están presentes evaporitas. Los cortes A y B presentan una discordancia qie se correlaciona estrechamente con el Mid-Cretaceous Sequence Boundary, detectado en el sur del golfo de México y el estrecho de La Florida. Las similitudes, en particular entre las regiones A y B, indican una misma identidad geológica. Su posición actual, yuxtapuestos a las plataformas de Bahamas y Yucatán de la placa norteamericana, y su bien confirmado tránsito a los cortes de Bahamas en el norte de Cuba central, indican que los cortes del PPS deben formar parte del margen pasivo mesozoico de la América del Norte. La continuación al este de los cortes de Guaniguanico es visible en varios afloramientos y registrada por numerosos pozos de prospección desde el oeste de La Habana hasta Matanzas. Por tanto, no hay razón para considerar los cortes de Guaniguanico como parte de los "terrenos sudoccidentales". Siguiendo esta

San Miguel volcano, also known as Chaparrastique, is a basaltic volcano along the Central American Volcanic Arc (CAVA). Volcanism is induced by the convergence of the Cocos Plate underneath the Caribbean Plate, along a 1200-km arc, extending from Guatemala to Costa Rica and parallel to the Central American Trench. The volcano is located in the eastern part of El Salvador, in proximity to the large communities of San Miguel, San Rafael Oriente, and San Jorge. Approximately 70,000 residents, mostly farmers, live around the crater and the city of San Miguel, the second largest city of El Salvador, ten km from the summit, has a population of ~180,000 inhabitants. The Pan-American and Coastal highways cross the north and south flanks of the volcano.San Miguel volcano has produced modest eruptions, with at least 28 VEI 1-2 events between 1699 and 1967 (datafrom Smithsonian Institution http://www.volcano.si.edu/volcano.cfm?vn=343100). It is characterized by visible milddegassing from a summit vent and fumarole field, and by intermittent lava flows and Strombolian activity. Since the last vigorous fire fountaining of 1976, San Miguel has only experienced small steam explosions and gas emissions, minor ash fall and rock avalanches. On 29 December 2013 the volcano erupted producing an eruption that has been classified as VEI 2. While eruptions tend to be low-VEI, the presence of major routes and the dense population in the surrounding of the volcano increases the risk that weak explosions with gas and/or ash emission may pose. In this study, we present the first inventory of SO2, CO2, HCl, and HF emission rates on San Miguel volcano, and an analysis of the hazard from volcanogenic SO2 discharged before, during, and after the December 2013 eruption. SO2 was chosen as it is amongst the most critical volcanogenic pollutants, which may cause acute and chronicle disease to humans. Data were gathered by the geochemical monitoring network managed by the Ministerio de Medio Ambiente

2011-01-01

SANS (Small Angle Neutron Scattering) is a popular method for elucidation of nano-scale structures. However science continually challenges SANS for higher performance, prompting exploration of ever-more exotic and expensive technologies. We propose a compact high resolution SANS, using very cold neutrons, magnetic focusing lens and a wide-angle spherical detector. This system will compete with modern 40 m pinhole SANS in one tenth of the length, matching minimum Q, Q-resolution and dynamic range. It will also probe dynamics using the MIEZE method. Our prototype lens (a rotating permanent-magnet sextupole), focuses a pulsed neutron beam over 3-5 nm wavelength and has measured SANS from micelles and polymer blends. (authors)

Full Text Available Background: The participation of Colombian coal in the international market has depended and will depend primarily on price to compete with other potential international suppliers, if the strategy is not changed to compete. Therefore one of the most important factors to consider has to do with the cost of logistics operation, in the case of Norte de Santander. Objective: The main objective of this project is to make the diagnosis of coal logistics operation in Northern Santander. Methods: Basically the methodology used was the application of polls leading experts and entrepreneurs exporters of coal in Norte de Santander. Results: One of the most important aspects that mitigate the possibility of capturing value in foreign trade are high costs in logistics operation. The identified problem occurs in the absence of studies to characterize the international physical distribution of coal in Norte de Santander, the most representative for extraction Municipalities sector. Conclusions: Finally the internationalization of the economy requires productive sectors, to shift from comparative advantages to competitive advantages. These are needed to tap international markets, however, strategic sectors for its potential reserves and features of your product, as the coal sector in Norte de Santander, not yet consolidated elements for their use.

Climate-induced forest dieback as an emergent global phenomenon: Organized oral session at the Ecological Society of America/Society of Ecological Restoration Joint Meeting; San Jose, California, 5-10 August 2007

Science.gov (United States)

Allen, Craig D.; Breshears, David D.

2007-01-01

An organized oral session at the annual meeting of the Ecological Society of America in San Jose, Calif., posed this question: Is climate-induced drought stress triggering increasing rates and unusual patterns of forest die-off at a global scale? Twenty-nine researchers representing five continents reported on patterns, mechanisms, and projections of forest mortality.Observations include widespread forest dieback or reductions in tree cover and biodiversity in response to drought and warmer temperatures in the African Sahel (Patrick Gonzalez, The Nature Conservancy), Mediterranean and alpine Europe (Jorge Castro, Universidad de Granada), and Argentinean Patagonia (Thomas Kitzberger, Universidad Nacional del Comahue). In contrast, although much Eucalyptus mortality has resulted from recent droughts in Australia, warming trends have been less pronounced in the Southern Hemisphere and it is unclear if contemporary climate-induced tree mortality differs from previous historical drought impacts (Rod Fensham, Queensland Herbarium).

Es un momento muy importante en el que se refuerza la cohesión de los tepehuanos que tienen un patrón de asentamiento muy disperso, como los demás grupos del norte, pero sus rituales presentan también similitudes con los mesoamericanos.

Summary Introduction Leprosy is a public health problem in Brazil where 31,044 new cases were detected in 2013. Rio Grande do Norte is a small Brazilian state with a rate of leprosy lower than other areas in the same region, for unknown reasons. Objectives We present here a review based on the analysis of a database of registered leprosy cases in Rio Grande do Norte state, comparing leprosy's geographic distribution among municipalities with local socio-economic and public health indicators and with historical documents about human migration in this Brazilian region. Results The current distribution of leprosy in Rio Grande do Norte did not show correlation with socio-economic or public health indicators at the municipal level, but it appears related to economically emerging municipalities 100 years ago, with spread facilitated by railroads and train stations. Drought-related migratory movements which occurred from this state to leprosy endemic areas within the same period may be involved in the introduction of leprosy and with its present distribution within Rio Grande do Norte. Conclusions Leprosy may disseminate slowly, over many decades in certain circumstances, such as in small cities with few cases. This is a very unusual situation currently and a unique opportunity for epidemiologic studies of leprosy as an emerging disease. PMID:26964429

La nostalgie des jours heureux contre le vent rude et glacial de l’exil, chez Jorge Semprun

Beatriz Coca Méndez

2013-11-01

Full Text Available Semprun recalled: "my only identity link was my own memory", link also nurtured by his poetic memory, from which it drew the words that give life to his stories. There are also narrative processes that Jorge Semprun used in Adieu, vive clarté…, in order to witness the devastated landscape of his soul: his exile, deportation and life underground. Indeed, for Semprun to cultivate the memory and the testimony is necessary to frame the moral of the resistance in the context of his experiences. In addition, it is through writing that Semprun found freedom and the dignity of human beings. If this was expressed in French this linguistic choice relates to bilingual stateless status which characterizes the author.

Book review, Amati cani, José Jorge Letria

2008-03-01

Full Text Available Con Amati cani ci discostiamo per una volta dalle pubblicazioni a carattere scientifico, per dare il giusto risalto ad un’interessante raccolta di narrativa che esplora il rapporto tra l'uomo e il suo miglior amico. José Jorge Latria, noto soprattutto per essere un esponente di spicco della canzone politica portoghese e per le sue opere poetiche, teatrali e di letteratura per ragazzi, nello scrivere questo libro compie un vero e proprio atto d’amore verso i cani, con il preciso intento di costringere i lettori ad eliminare dal proprio vocabolario il gratuito modo di dire ‘mondo cane’. L’Autore delinea brevi ritratti di cani che, da Argo in poi, hanno accompagnato da amici veri i loro celebri padroni nella buona e nella cattiva sorte: racconta cioè la storia di quei cani che non sono sprofondati nella voragine dell’oblio perchè i loro padroni hanno raggiunto la celebrità nel mondo della letteratura, della politica, del cinema, delle scienze o della musica. Con a fianco un amico fedele come un cane, la vita ha avuto un sapore diverso per Ernest Hemingway, Isaac Newton, Sigmund Freud, Buster Keaton, Marilyn Monroe, Pablo Picasso, John Steinbeck, Lord Byron, Tim Burton e altri ancora, tutti personaggi che sono presenti in questo libro grazie ai cani che hanno condiviso con loro la vita e le memorie. La lettura di Amati cani dà piacere poichè in ognuno di questi racconti batte, affettuoso e delicato, il cuore di un cane; ma dà anche un pò da pensare in quanto celebra in maniera molto tenera l’amore, la fedeltà e la solidarietà tra l’uomo e il suo speciale amico a quattro zampe.

The human dimension of AIDS in Cuba: Jorge Pérez MD MS, Director, Pedro Kourí Tropical Medicine Institute. Interviewed by Gail Reed.

Pérez, Jorge

2011-04-01

Except for the people living with the disease, no others have so immersed themselves in Cuba's world of HIV/AIDS as Dr Jorge Pérez. It is a world of Cuban returnees from Angola's war against apartheid South Africa, gay and bisexual men, housewives, transactional sex workers, rebellious teenagers, and infected surgeons and scientists-a cultural kaleidoscope reflecting all the faces of AIDS. To more than one international author, he is simply "Cuba's AIDS doctor." Speaking to his patients at the Pedro Kourí Tropical Medicine Institute in Havana, it is easy to see why, but also to appreciate the courage, compassion, and persistent search for new knowledge that characterize the Institute's staff as a whole. Dr Pérez's story-now told in two books based on his diaries-is not his alone. MEDICC Review held two interview sessions with Jorge Pérez just days apart at the beginning of April: one before and one after his designation as the new Director of the Tropical Medicine Institute, where he previously served as Deputy Director and Chief of Hospital Services. More than strictly medical matters, the conversation turned to the human dimension of HIV/AIDS, the depth to which it has touched many directly and affected Cuban society as a whole, and the challenges ahead for Cuba's flagship institution for research and treatment of infectious diseases.

Renditions of Faithfulness; from Jorge Calvetti’s Poetry to Gustavo Fontán’s Films.

Directory of Open Access Journals (Sweden)

Adriana C. Cid

2015-04-01

Full Text Available An original and sensitive filmmaker, Gustavo Fontán goes beyond classic transpositions to venture into a poet’s obsessions, aesthetic and atmospheres. He has done so with the work of Jacobo Fijman, Juan L. Ortiz and Jorge Calvetti – to name just a few. In this paper I intend to explore El paisaje invisible, a short film by Fontán that brings us closer to Calvetti. I will focus on the director’s strategies – characteristic of the cinematographic language - that convey the poet’s mythical world and aesthetic, and I will analyze the union of both artists’ poetics. Finally, I would like to offer a brief explanation of the title of this article, which is drawn from a reflection by Calvetti: “All inspiration is born with its own form or forms. The same subject can be written as a narrative or in verse. Why not? They are different renditions of faithfulness.” I believe cinema is another rendition.

San Marino, an independent republic located in north central Italy, in 1983 had a population of 22,206 growing at an annual rate of .9%. The literacy rate is 97% and the infant mortality rate is 9.6/1000. The terrain is mountainous and the climate is moderate. According to local tradition, San Marino was founded by a Christian stonecutter in the 4th century A.D. as a refuge against religious persecution. Its recorded history began in the 9th century, and it has survived assaults on its independence by the papacy, the Malatesta lords of Rimini, Cesare Borgia, Napoleon, and Mussolini. An 1862 treaty with the newly formed Kingdom of Italy has been periodically renewed and amended. The present government is an alliance between the socialists and communists. San Marino has had its own statutes and governmental institutions since the 11th century. Legislative authority at present is vested in a 60-member unicameral parliament. Executive authority is exercised by the 11-member Congress of State, the members of which head the various administrative departments of the goverment. The posts are divided among the parties which form the coalition government. Judicial authority is partly exercised by Italian magistrates in civil and criminal cases. San Marino's policies are tied to Italy's and political organizations and labor unions active in Italy are also active in San Marino. Since World War II, there has been intense rivalry between 2 political coalitions, the Popular Alliance composed of the Christian Democratic Party and the Independent Social Democratic Party, and the Liberty Committee, coalition of the Communist Party and the Socialist Party. San Marino's gross domestic product was $137 million and its per capita income was $6290 in 1980. The principal economic activities are farming and livestock raising, along with some light manufacturing. Foreign transactions are dominated by tourism. The government derives most of its revenue from the sale of postage stamps to

Pero Isaacs, además, fue un político liberal radical que llevó adelante una revolución, en enero de 1880, movido por sus principios ideológicos en medio de lo que él consideraba la traición de los liberales. La revolución, embebida de romanticismo, fue una empresa romántica destinada al fracaso desde un principio. Este artículo, a partir del estudio de los documentos de la época, analiza de qué manera Isaacs desarrolló sus actividades militantes, como superintendente de Educación, primero, como congresista, después, y como revolucionario, en el marco del proceso de recuperación del poder por parte de los conservadores. Asimismo, este artículo se enfoca en el espíritu romántico que animó a Isaacs y cómo se expresó a través de la palabra encendida de los manifiestos, proclamas, cartas e informes recopilados por el propio Isaacs en su libro La revolución radical en Antioquia (1880.   Jorge Isaacs is well-known for Maria (1867, which is considered the most important novel of Latin American romanticism.

Visioni apocalittiche in El cuerpo de Giulia-no di Jorge Eduardo Eielson

Giovanna Minardi

2013-06-01

Full Text Available Jorge Eduardo Eielson is a well-known poet and plastic artist, but his narrative works remain little-known, even in his native Peru. El cuerpo de Giulia-no is a discontinous and elusive text. Written in the 1950s but not published until 1971 in Mexico, it is an undoubtedly innovative work which thwarts the readers’s expectations with its fragmentary composition, elliptical tendencies, and the underlying dislogue amongst literature, visual arts and science running throughout the text. Like a typical Eislson work, it is a ‘chaotic’ text, which brings together the themes of the indigenist conflict and the Apocalypse emboded by the crisis of language with elements of meta-theatre and science fiction. I focus on the parody of science fiction within the novel. The world of the future, that anticipated in science fiction, is, for Eielson, the present world. Thus he represents, in the contemporary context, the cultural conflict with the indigenous world though a sort of ‘alien’ invasion (indigenous people which is controlled and repressed, the origins of which can be found in the history of Peru. However, through this sort of ‘ontological break’, Eielson let us see the first steps toward the foundation of a new order out of chaos.

The Red Odyssey. Several lines to the political portrait of Jorge Vivo d’Escoto

Víctor Jeifets

2014-12-01

Full Text Available Despite of the partial opening of the archives of the Communist International, there are still many white spots in history of international communism and of a number of national Communist Parties. This is due to the fact that information about the activities of many militants and leaders of the left-wing groups and parties is not readily available to the general public. The Communist Party of Cuba (PCC, the only ruling communist party in Latin America, did not manage to avoid this problem either. The paper intents to narrow the gap by revealing some of the main events in the life and political activities of Jorge A. Vivó d’Escoto , a “forgotten Secretary-General” who was at the top of PCC in the beginning of the 1930s. The paper also describes his role in the development of Central American, Colombian, and Mexican left-wing parties. The article is based on the analysis of a vast quantity of primary sources from Russian and Mexican archives.

Full Text Available The growth and reproduction investment of the young of the year (0+ of the squat lobster Munida gregaria in San Jorge Gulf, Argentina, were analysed. Moult cycle and size frequency distribution were studied in monthly field samples. Experiments to determine moult increments and intermoult duration were conducted. Sexual maturity, fecundity and reproductive output were analysed in field samples. In addition, maturity experiments in laboratory cultures were conducted. After settlement (November, juveniles showed fast growth until winter (July and growth restarted in September-October. At the beginning of the mating period (early June, males 0+ exhibited mature gonads, whereas females 0+ only showed previtellogenic oocytes. Experimental data showed that females with developed gonads had smaller-size increments in the previous moult. Fecundity and reproductive output were significantly lower in females 0+ than in older females. The early life history of M. gregaria in San Jorge Gulf differs from that of southern populations as those of Beagle Channel and Strait of Magellan due to faster growth and early reproductive investment. Our results suggest that females 0+ of M. gregaria have two investment strategies: early maturity with low fecundity and delayed maturity with higher future fecundity.

This seems to indicate the emergence of a new pedagogical logos, which attemptsper haps to overcome the frontiers ofreflection imposed by the so-called “sciences of education”. Some of the approaches, however, not only display visible and understandable limitations,such as the absence of a receptiontheory of fictional texts, but alsodemonstrate the ambition ofrevolutionising pedagogic discoursethrough literature by transforming it intoan aesthetics of existence project.

Apesar das contestações quanto ao caráter improdutivo do modelo tradicional de produção local, diversos Estados africanos têm estabelecido acordos internacionais de investimento com vistas à modernização de sua agricultura. Nesse contexto, surge o acordo trilateral entre Japão, Brasil e Moçambique, que possibilitará a implementação neste país do Prosavana, o programa de desenvolvimento agrícola da Savana moçambicana.

Territorio flexible en la semiperiferia: La frontera norte mexicana

Full Text Available En este trabajo se realiza una discusión sobre la aplicabilidad de la propuesta de la denominada corriente regulacionista en torno a la espacialidad de los procesos recientes de industrialización, para un caso dentro de los países no centrales, en particular sobre el proceso de industrialización ocurrido en la Frontera Norte mexicana, desde mediados de la década pasada. Lo que se cuestiona, primeramente, a nivel teórico, es la utilidad de esta propuesta para parte de los estados no-centrales del Sistema Mundial. También se desarrollan, en el mismo plano, las objeciones principales en relación a sus supuestos generales al aplicarse esta teoría tanto al centro del Sistema Mundial como también al resto de ésta. Las características principales de este reciente proceso de industrialización en el territorio del norte mexicano son esbozadas para luego ser confrontadas a los supuestos subyacentes a la teoría regulacionista. Desde la crítica formulada a esta escuela de pensamiento, se genera una propuesta interpretativa, basada primeramente sobre el concepto de espacio de flujos, y después sobre la flexibilidad en el uso de la región fronteriza del norte mexicanoA debate is proposed in this paper on the suitability of the regulationist proposal to explain the spatial implications of recent industrial processes. This suitability is questioned for a particular territory in a non-central Nation-State, the Mexican Northern Border, from the mid-dle 1980´s. At a theoretical level, the usefulness of this for parts of the non-central nations of the World-System. On the same level the main objections on its general assumptions when this theory is applied to the center of the World-System as well as to the rest of it.

The whole-rock K-Ar dates from porphyry copper prospects of Paramillos Sur (phyllic and potasic alteration zones) and Paramillos Norte (propilitic zone) are reported. Radiometric data yielded 17,8 {+-} 0,9 Ma, 15,8 {+-} 1,0 Ma and 15,2 {+-} 0,5 Ma in Paramillos Sur, and 17,3 {+-} 0,7 Ma in Paramillos Norte, which can be added to an previously reported age of 16,4 {+-} 0,3 Ma. These data are in agreement with isotopic ages from non altered or non mineralized magmatic rocks of the region. When the isotopic ages and petrographic characteristics of the dated rocks are considered, two alteration-mineralization events are suggested for Paramillos Sur prospect. However this possibility needs to be confirmed by means of future studies, in view of the reduced interval between these events when compared with the analytical errors. (author)

A case for historic joint rupture of the San Andreas and San Jacinto faults.

Science.gov (United States)

Lozos, Julian C

2016-03-01

The San Andreas fault is considered to be the primary plate boundary fault in southern California and the most likely fault to produce a major earthquake. I use dynamic rupture modeling to show that the San Jacinto fault is capable of rupturing along with the San Andreas in a single earthquake, and interpret these results along with existing paleoseismic data and historic damage reports to suggest that this has likely occurred in the historic past. In particular, I find that paleoseismic data and historic observations for the ~M7.5 earthquake of 8 December 1812 are best explained by a rupture that begins on the San Jacinto fault and propagates onto the San Andreas fault. This precedent carries the implications that similar joint ruptures are possible in the future and that the San Jacinto fault plays a more significant role in seismic hazard in southern California than previously considered. My work also shows how physics-based modeling can be used for interpreting paleoseismic data sets and understanding prehistoric fault behavior.

Latin American Marxism paper . The editorial policy of Jorge Abelardo Ramos in the early sixties

Directory of Open Access Journals (Sweden)

Martín Ribadero

2016-03-01

Full Text Available The importance of the Marxism in the Latin-American thought has been indicated in repeated opportunities. Its aptitude to generate diverse political and cultural projects was a central characteristic of the above mentioned tradition, opened across different agents and institutions from the arrival of the writings of Marx and Engels to Latin America at the end of the XIXth century. Nevertheless, good part of this history is still partial, anchored in national perspectives and little commits an outrage against the study of its material forms, this is, to those aspects across which the Marxist speech managed to shape a specific materiality, so much for the theoretical making as the action of militants, workers, students and intellectuals. The work aims to propose an exploration of the Latin-American Marxism from the perspective of the reconstruction of its printed world, from delineating a series of problems, topics and reflections settled in the study of the publishing house Coyoacán of Jorge Abelardo Ramos in the early 1960s in Argentina

Full Text Available Three contemporary movie narratives produced in Rio Grande do Sul by Jorge Furtado were analized. The objective is to investigate the films from the point of view of genre in the cultural and relational dimensions of the category, showing the differences between the female characters. The three movies chosen for this debate are: Houve uma Vez Dois Verões (2002, O Homem que Copiava (2003 and Meu Tio Matou um Cara (2004. Although the movies have the narration by the male characters in off, there are the women who, preponderantly break out the plot conflicts. From this observation it was concluded that the dynamics of the male´s view has been flexible, although keeping some of their original characteristics.

De las obras de arquitectura popular en América, las mexicanas requieren especial consideración, ya que a pesar de la ubicación geográfica de México en América del Norte, su cultura permanece fuertemente arraigada. Esta suerte de independencia en hábitos y ritos se refleja en la arquitectura mexicana vernácula, lo que nos da la oportunidad de analizarla como un fenómeno cultural extendido desde México al Norte de California. Veremos aquí que las raíces del imaginario mexicano se hunden en la Conquista española y surgen en la actualidad dando como resultado una "nueva" estética arquitectónica.

Coastlines around the world are under ever-increasing pressure due to population trends, commerce, and geophysical processes like tropical storms and erosion. This multi-institutional field campaign was conducted to improve our understanding of complex nearshore processes under varying forcing conditions on a microtidal, sandy beach located in Sisal, Yucatan from 3/27 to 4/12/2014. Hydrodynamics, morphodynamics, and textural variability were investigated during: (1) a cold front event (referred to as El-Norte); (2) land breeze (LB); and (3) sea breeze (SB). The instrumentation layout included three surf/swash zone cross-shore transects where water elevation, suspended sediment concentration, bed load, and current velocities were measured, as well as several offshore ADCP for hydrodynamic measurements. TKE, τb, ɛ and were estimated using the data obtained from surf zone ADV. In addition, Hs and Tsin the surf zone were computed using measurements from ADV pressure sensors, while a separate pressure transducer was used to obtain water free-surface elevation within the swash zone. During SB cycles the study area experienced wind velocities reaching up to 12ms-1, and 15ms-1 during El-Norte. Elevated wind stress during El-Norte resulted in Hs of 1.5m and 0.6m in water depths of 10m and 0.4m, respectively. Surface sediment grab samples during SB/LB cycles showed that the swash zone had a moderately well sorted distribution with a mean grain size of 0.5mm, while poor sorting and a mean grain size of 0.7mm were found during El-Norte. Additionally, measured bathymetry data showed evidence for offshore sandbar migration during strong offshore currents (0.4ms-1) during El-Norte, while onshore sandbar migration was evident during SB/LB periods (0.3ms-1 and 0.1ms-1, respectively). This study highlights how different weather forcing conditions affect hydrodynamics, morphodynamics, and textural variability on a sandy beach. Aside from furthering our knowledge on these complex

2003-03-01

SANS data from some standard samples have been obtained using BATAN-SANS instrument in Serpong. The experiments were performed for various experimental set-ups that involve different detector positions and collimator lengths. This paper describes the BATAN-SANS instrument briefly as well as the data taken from those experiments and followed with discussion of the results concerning the performance and calibration of the instrument. The standard samples utilized in these experiments include porous silica, polystyrene-poly isoprene, silver behenate, poly ball and polystyrene-poly (ethylene-alt-propylene). Even though the results show that BATAN-SANS instrument is in good shape, but rooms for improvements are still widely open especially for the velocity selector and its control system. (author)

The Wall as a Spatial Work: the Reliefs of Jorge Oteiza in Architecture (1951-58

Emma López Bahut

2014-03-01

Full Text Available This paper analyses the mural projects of Basque sculptor Jorge Oteiza on façades and internal walls between the years 1951-58. At first, he dealt with walls as ground planes on which to execute his sculptures, finally viewing them as an empty plane with spatial possibilities, defined by the minimum forms and the action of natural light. Based on original, previously unpublished material, we explore the evolution of this work with the aim of establishing to what extent this process was marked by the architecture on which his work was executed, by the architects with whom he collaborated, or the stage of his sculptural experimentation with which they are associated. We show that apart from the presence of an architect, there is a correlation between the way in which the reliefs were applied to the wall and the work carried out on the space where the project was created: the larger the spatial work on the wall, the greater the relationship with the space within which it was inserted, at every scale, from the interior of the architecture to the urban space.

A case for historic joint rupture of the San Andreas and San Jacinto faults

The San Andreas fault is considered to be the primary plate boundary fault in southern California and the most likely fault to produce a major earthquake. I use dynamic rupture modeling to show that the San Jacinto fault is capable of rupturing along with the San Andreas in a single earthquake, and interpret these results along with existing paleoseismic data and historic damage reports to suggest that this has likely occurred in the historic past. In particular, I find that paleoseismic data...

Full Text Available Archeological evidence suggest that the cultural developments occurred in the highlands around lake Titicaca in the Central Andes, exerted influence on the cultural elaborations of the human groups that peopled the valley of Azapa, close to the city of Arica, and the Pacific coast of northern Chile. In this communication we show by means of a distance analysis, that a craniofacial differentiation accompanied the process of cultural evolution in the valley. The biological influence of Tiwanaku is partially reflected in craniofacial morphology, providing preliminary evidence that cultural changes were associated to intermittent gene flow from the highlands, specially during the Alto Ramírez and San Miguel phasesLos desarrollos culturales ocurridos en el altiplano en el área circumtiticaca en los Andes centrales, ejercieron influencia sobre las elaboraciones culturales de los grupos humanos que poblaban el Valle de Azapa cercano a la ciudad de Arica y la costa del norte de Chile.

Full Text Available El objetivo del presente artículo consiste en proponer una relectura de la novela El museo de cera, que el escritor chileno Jorge Edwards publicó en 1981, concentrando la atención no sólo en la habitual interpretación crítica que evidencia la lúcida condena satírica del pensamiento reaccionario chileno, sino abordando la trama desde una perspectiva que ilumina la relación entre tiempo individual y colectivo. En paralelo, se examina la representación de la decadencia de una arquitectura sociopolítica, poniendo en relación las imágenes ficcionales de Edwards con las representaciones del declive presentes en la narrativa austrohúngara de comienzos del siglo xx. Se analizan, finalmente, las dinámicas de ósmosis entre los dos espacios geosociales descritos en la ficción evidenciando la permeabilidad de sectores en apariencia opuestos.The purpose of the present article consists of proposing a different interprtetation of the novel El museo de cera, which the Chilean writer Jorge Edwards published in 1981: we will concentrate not only in the habitual critical interpretation that confirms the lucid satirical sentence of the reactionary Chilean thought, but we will approach the plot from a perspective that demonstrates the relation between individual and collective time. At the same time, we analyze the representation of the decadence of a social and political structure, by connecting the fictional images from Edwards with the representations of the decline presented in the Austro-Hungarian narrative of the beginning of the 20th century. Finally, we examine the dynamics of osmosis between the two geosocial contexts described in the fiction demonstrating the permeability of sectors by all appearances opposite.

Full Text Available The city of Londrina (north of Paraná State emancipated politically on December 10, 1934, five years after the arrival of the pioneers of the Companhia de Terras Norte do Paraná (CTNP - mostly English owned company that began colonization in 1929. In October 1934, two months before being elevated to the status of municipality, was born the first communication vehicle in the city, the newspaper Paraná-Norte. Present from the beginning, the press reported on its pages the transformations that city suffered through the years, being a document of important historical value. This study therefore aims to analyze the beginning of the trajectory ofLondrina's press from the place occupied by the image in the pages of the city's first newspaper, Paraná-Norte (1934-1953 and the magazine A Pioneira (1948-1954. To understand the importance of photography published in such vehicles as trace for writing the history ofLondrina, it employed some research methodologies. The first was the literature, followed by the documentary analysis (MOREIRA, 2009 for all editions of the newspaper and magazine available to the public consultation, which allowed to write about the history of the two media pioneers. Already a comparative study of photography in Paraná-Norte and A Pioneira was done by iconographic analysis, proposed by Kossoy (2001. Faced with the impossibility of studying the universe of photographs published by two journals, we chose to select, via random draw, one copy per year of circulation newspaper and magazine. Thus, the study focused on 18 editions of Paraná-Norte (for the years 1951 and 1952 there are no copies available and 7 of the magazine A Pioneira. Drawing on theoretical frameworks that deal with interfaces between story and image, press photography and memory, portraits and family albums, we conclude that, although the use of imagery has been explored differently by the two vehicles, even because of difficulties technical and financial, in

El ser humano ha sido capaz de adaptarse a estos microambientes optimizando sus asentamientos para poder aprovechar los recursos que se encuentran en cada uno de éstos. Este trabajo se enfoca en la zona costera del centro-norte de Yucatán y su trayectoria hacia el interior, donde linealmente se puede hallar una sucesión de tales nichos y donde con base en la información arqueológica obtenida mediante varios proyectos de prospección y salvamento arqueológico en la región, se pueden identificar diferencias importantes en el patrón de asentamiento y las características de las  estructuras. Dichos datos a la vez, brindan la pauta para comprender el tipo de relaciones que los habitantes de la zona mantuvieron con el entorno y la forma como se han adaptado a través del tiempo.

This article discusses the development of techniques for cesarean sections by doctors in Brazil, during the 20th century, by analyzing the title "Operação Cesárea" (Cesarean Section), of three editions of the textbookObstetrícia, by Jorge de Rezende. His prominence as an author in obstetrics and his particular style of working, created the groundwork for the normalization of the practice of cesarean sections. The networks of meaning practiced within this scientific community included a "provision for feeling and for action" (Fleck) which established the C-section as a "normal" delivery: showing standards that exclude unpredictability, chaos, and dangers associated with the physiology of childbirth, meeting the demand for control, discipline and safety, qualities associated with practices, techniques and technologies of biomedicine.

1998-01-01

The whole-rock K-Ar dates from porphyry copper prospects of Paramillos Sur (phyllic and potasic alteration zones) and Paramillos Norte (propilitic zone) are reported. Radiometric data yielded 17,8 ± 0,9 Ma, 15,8 ± 1,0 Ma and 15,2 ± 0,5 Ma in Paramillos Sur, and 17,3 ± 0,7 Ma in Paramillos Norte, which can be added to an previously reported age of 16,4 ± 0,3 Ma. These data are in agreement with isotopic ages from non altered or non mineralized magmatic rocks of the region. When the isotopic ages and petrographic characteristics of the dated rocks are considered, two alteration-mineralization events are suggested for Paramillos Sur prospect. However this possibility needs to be confirmed by means of future studies, in view of the reduced interval between these events when compared with the analytical errors. (author)

Full Text Available Se evaluaron 57 explotaciones lecheras representativas del altiplano Norte de Antioquia, correspondientes a los municipios de Belmira, Entrerrios, San Pedro de los Milagros, Don Matías Santa Rosa de Osos, San José de la Montaña y Yarumal. La zona está situada entre 2200 y 2550 msnm y tiene precipitaciones anuales entre 2060 y 4000 mm La topografía predominante es ondulada y los suelos de textura franco-arenosa, son ácidos y de baja fertilidad. Se trabajó mediante una encuesta inicial sobre características generales de la explotación y luego se realizó un monitoreo, durante 6 meses, sobre los parámetros productivos y reproductivos. El análisis de la información se realizó mediante estadística descriptiva. El tamaño de las fincas, predominante en la zona, es de menos de 50 hectáreas y con promedio de 42 animales, en su mayoría de raza Holstein. Los pastos predominantes son kikuyo (Pennisetun clandestinum, y en segundo lugar la falsa poa (Holcus lanalus. Un 90-100 % de las fincas utilizan fertilizante químico y hasta un 70 % de ellas, aplican porquinaza, pero solo un 40-50% utilizan encalamiento; sin embargo es necesaria mucha transferencia tecnológica acerca del manejo adecuado de pasturas. Los insectos plagas chinche (Collaria sp y lorito verde (Draeculacephala sp, causan daño grave en las praderas y se requieren alternativas viables para su control. El uso de suplementos concentrados en vacas y novillas es inadecuado y son requeridas acciones de transferencia tecnológica, relacionadas con el uso eficiente de ellos. Solamente el 24 %de los ganaderos usa inseminación artificial, pero parece ser más importante el problema alimenticio en la zona. La crianza de las terneras se realiza en base a leche, suministrando 200-400 litros en períodos entre 60 y 120 días, con muy poco uso de suplemento concentrado. La producción de leche por vaca/día está entre 10.5-12.1 litros, acorde con el programa alimenticio

Soil CO2 Degassing Path along Volcano-Tectonic Structures in the Pico-Faial-São Jorge Islands (Azores Archipelago, Portugal

Full Text Available The Azores archipelago is composed of nine volcanic islands located at the triple junction between the North American, Eurasian, and Nubian plates. Nowadays the volcanic activity in the archipelago is characterized by the presence of secondary manifestations of volcanism, such as hydrothermal fumaroles, thermal and cold CO2-rich springs as well as soil diffuse degassing areas, and low magnitude seismicity. Soil CO2 degassing (concentration and flux surveys have been performed at Pico, Faial, and São Jorge islands to identify possible diffuse degassing structures. Since the settlement of the Azores in the fifteenth Century these three islands were affected by seven onshore volcanic eruptions and at least six destructive earthquakes. These islands are crossed by numerous active tectonic structures with dominant WNW-ESE direction, and less abundant conjugate NNW-SSE trending faults. A total of 2,855 soil CO2 concentration measurements have been carried out with values varying from 0 to 20.7 vol.%. Soil CO2 flux measurements, using the accumulation chamber method, have also been performed at Pico and Faial islands in the summer of 2011 and values varied from absence of CO2 to 339 g m−2 d−1. The highest CO2 emissions were recorded at Faial Island and were associated with the Pedro Miguel graben faults, which seem to control the CO2 diffuse degassing and were interpreted as the pathways for the CO2 ascending from deep reservoirs to the surface. At São Jorge Island, four main degassing zones have been identified at the intersection of faults or associated to WNW-ESE tectonic structures. Four diffuse degassing structures were identified at Pico Island essentially where different faults intersect. Pico geomorphology is dominated by a 2,351 m high central volcano that presents several steam emissions at its summit. These emissions are located along a NW-SE fault and the highest measured soil CO2 concentration reached 7.6 vol.% with a maximum

Full Text Available In this article I analyse two autobiographical narrations that have recently been published by the sons of southern Spanish migrants to Catalonia. In Paseos con mi madre by Javier Pérez Andújar (2011, and La vida iba en serio by Jorge Javier Vázquez (2013, the authors deal with their social condition as youngsters in the urban periphery, producing a discourse, written in the first person, that is unprecedented in the Catalan context. The relevance of these books derives from a number of factors. First, they offer a new voice that rises out of a self-representation vacuum in this social sector. Secondly, they conflictively rethink a social place which hegemonic discourse had assumed «normalized» and overcome. Thirdly, although both reflect on their migratory origin and the difficulty of fitting into Catalonia’s urban mesocracy, their migratory background is largely subsumed in the experience of urban segregation, and hardly expressed at all in either ethnic or national terms.En este artículo analizo dos relatos autobiográficos publicados recientemente por hijos de inmigrantes procedentes del sur de España y radicados en Cataluña.

Emission inventories of ozone precursors are routinely used as input to comprehensive photochemical air quality models. Photochemical model performance and the development of effective control strategies rely on the accuracy and representativeness of an underlying emission inventory. This paper describes the tasks undertaken to compile and evaluate an ozone precursor emission inventory for the El Paso/Ciudad Juarez/Southern Dona Ana region. Point, area and mobile source emission data were obtained from local government agencies and were spatially and temporally allocated to a gridded domain using region-specific demographic and land-cover information. The inventory was then processed using the US Environmental Protection Agency (EPA) recommended Emissions Preprocessor System 2.0 (UAM-EPS 2.0) which generates emissions files compatible with the Urban Airshed Model (UAM). A top-down evaluation of the emission inventory was performed to examine how well the inventory represented ambient pollutant compositions. The top-down evaluation methodology employed in this study compares emission inventory ratios of non-methane hydrocarbon (NMHC)/nitrogen oxide (NO{sub x}) and carbon monoxide (CO)/NO{sub x} ratios to corresponding ambient ratios. Detailed NMHC species comparisons were made in order to investigate the relative composition of individual hydrocarbon species in the emission inventory and in the ambient data. The emission inventory compiled during this effort has since been used to model ozone in the Paso del Norte airshed (Emery et al., CAMx modeling of ozone and carbon monoxide in the Paso del Norte airshed.

We examine the Pleistocene tectonic reorganization of the Pacific-North American plate boundary in the Salton Trough of southern California with an integrated approach that includes basin analysis, magnetostratigraphy, and geologic mapping of upper Pliocene to Pleistocene sedimentary rocks in the San Felipe Hills. These deposits preserve the earliest sedimentary record of movement on the San Felipe and San Jacinto fault zones that replaced and deactivated the late Cenozoic West Salton detachment fault. Sandstone and mudstone of the Brawley Formation accumulated between ???1.1 and ???0.6-0.5 Ma in a delta on the margin of an arid Pleistocene lake, which received sediment from alluvial fans of the Ocotillo Formation to the west-southwest. Our analysis indicates that the Ocotillo and Brawley formations prograded abruptly to the east-northeast across a former mud-dominated perennial lake (Borrego Formation) at ???1.1 Ma in response to initiation of the dextral-oblique San Felipe fault zone. The ???25-km-long San Felipe anticline initiated at about the same time and produced an intrabasinal basement-cored high within the San Felipe-Borrego basin that is recorded by progressive unconformities on its north and south limbs. A disconformity at the base of the Brawley Formation in the eastern San Felipe Hills probably records initiation and early blind slip at the southeast tip of the Clark strand of the San Jacinto fault zone. Our data are consistent with abrupt and nearly synchronous inception of the San Jacinto and San Felipe fault zones southwest of the southern San Andreas fault in the early Pleistocene during a pronounced southwestward broadening of the San Andreas fault zone. The current contractional geometry of the San Jacinto fault zone developed after ???0.5-0.6 Ma during a second, less significant change in structural style. ?? 2007 by The University of Chicago.

the Miocene-Pliocene boundary is represented in this area. The lower tuff beds, outcropping at the southwest of San Fernando Sur, provided an age of 5.59 ± 0.04 Ma (late Miocene, Messinian). The others tuffs beds, both outcropping at the west-northwest of San Fernando Norte and overlaying the first one, gave an age of 4.79 ± 0.15 Ma and 4.72 ± 0.08 Ma (early Pliocene, Zanclean), respectively. These absolutes ages, together with the results of a sedimentological analysis, indicate that westward from San Fernando River, much of the areas mapped as Corral Quemado Formation correspond to the Andalhuala Formation; while part of the area considered as Punaschotter unit must be assigned to Corral Quemado Formation. Also, a thick tuff bed, recognized at the contact of Corral Quemado and Punaschotter, was considered as the previous one dated in 3.66 Ma, in Puerta de Corral Quemado locality.

Full Text Available Dos motivos fundamentales enmarcan el mundo de Cántico, la obra más representativa del poeta español Jorge Guillén. Por un lado, la exaltación de una realidad en la que el hombre depende de las cosas, de las cosas mudas que están a su alrededor. Una vivencia elemental —quizá la más elemental— en la que se descubre el mundo y en la que se revelan sus esencias con el simple hecho de nombrar, rasgo que guarda una íntima relación con la concepción analógica del universo, la de las correspondencias, que debe su origen al romanticismo y se sostiene en la fe en una comunicación verdadera con un mundo superior. Por otro lado está el tiempo, que en Cántico se reconoce por dos vertientes opuestas: una, en la que representa una amenaza, un elemento destructor, y otra, de naturaleza esencial, un tiempo mítico al que se le otorga la virtud de trascender la experiencia personal.

Cataclastic rocks of the San Gabriel fault—an expression of deformation at deeper crustal levels in the San Andreas fault zone

Anderson, J. Lawford; Osborne, Robert H.; Palmer, Donald F.

1983-10-01

The San Gabriel fault, a deeply eroded late Oligocene to middle Pliocene precursor to the San Andreas, was chosen for petrologic study to provide information regarding intrafault material representative of deeper crustal levels. Cataclastic rocks exposed along the present trace of the San Andreas in this area are exclusively a variety of fault gouge that is essentially a rock flour with a quartz, feldspar, biotite, chlorite, amphibole, epidote, and Fe-Ti oxide mineralogy representing the milled-down equivalent of the original rock (Anderson and Osborne, 1979; Anderson et al., 1980). Likewise, fault gouge and associated breccia are common along the San Gabriel fault, but only where the zone of cataclasis is several tens of meters wide. At several localities, the zone is extremely narrow (several centimeters), and the cataclastic rock type is cataclasite, a dark, aphanitic, and highly comminuted and indurated rock. The cataclastic rocks along the San Gabriel fault exhibit more comminution than that observed for gouge along the San Andreas. The average grain diameter for the San Andreas gouge ranges from 0.01 to 0.06 mm. For the San Gabriel cataclastic rocks, it ranges from 0.0001 to 0.007 mm. Whereas the San Andreas gouge remains particulate to the smallest grain-size, the ultra-fine grain matrix of the San Gabriel cataclasite is composed of a mosaic of equidimensional, interlocking grains. The cataclastic rocks along the San Gabriel fault also show more mineralogiec changes compared to gouge from the San Andreas fault. At the expense of biotite, amphibole, and feldspar, there is some growth of new albite, chlorite, sericite, laumontite, analcime, mordenite (?), and calcite. The highest grade of metamorphism is laumontite-chlorite zone (zeolite facies). Mineral assemblages and constrained uplift rates allow temperature and depth estimates of 200 ± 30° C and 2-5 km, thus suggesting an approximate geothermal gradient of ~50°C/km. Such elevated temperatures imply a

Case studies in live electronic music preservation : Recasting Jorge Peixinho's Harmónicos (1967-1986 and Sax-Blue (1984-1992

Full Text Available We present two examples of technology transfer from analogical to digital systems, in two works of live electroacoustic music by the Portuguese composer Jorge Peixinho (1940-1995, Harmónicos (1967 and Sax-Blue (1982. These works require the use of analogue technology that has become obsolete or difficult to access by the average performer. We think that migration from electronics to software, also referred as recast represents a necessary step to preserve live electroacoustic music. However, this process can pose multiple questions as it also relies on aesthetic considerations. In this case, we put on a considerable effort into understanding both the composer's intentions and the equipment operating mode and we think the solutions proposed are adequate to perform both works. Finally, we discuss some of the questions, solutions and limitations that arose with these recasts and how they can contribute to the sustainability problem concerning these works.

The disappearing San of southeastern Africa and their genetic affinities.

Southern Africa was likely exclusively inhabited by San hunter-gatherers before ~2000 years ago. Around that time, East African groups assimilated with local San groups and gave rise to the Khoekhoe herders. Subsequently, Bantu-speaking farmers, arriving from the north (~1800 years ago), assimilated and displaced San and Khoekhoe groups, a process that intensified with the arrival of European colonists ~350 years ago. In contrast to the western parts of southern Africa, where several Khoe-San groups still live today, the eastern parts are largely populated by Bantu speakers and individuals of non-African descent. Only a few scattered groups with oral traditions of Khoe-San ancestry remain. Advances in genetic research open up new ways to understand the population history of southeastern Africa. We investigate the genomic variation of the remaining individuals from two South African groups with oral histories connecting them to eastern San groups, i.e., the San from Lake Chrissie and the Duma San of the uKhahlamba-Drakensberg. Using ~2.2 million genetic markers, combined with comparative published data sets, we show that the Lake Chrissie San have genetic ancestry from both Khoe-San (likely the ||Xegwi San) and Bantu speakers. Specifically, we found that the Lake Chrissie San are closely related to the current southern San groups (i.e., the Karretjie people). Duma San individuals, on the other hand, were genetically similar to southeastern Bantu speakers from South Africa. This study illustrates how genetic tools can be used to assess hypotheses about the ancestry of people who seemingly lost their historic roots, only recalling a vague oral tradition of their origin.

Some attempts at a geological explanation for the origin of the Sierra Nevada de Santa Marta in the Nineteenth Century: the naturalists Joaquin Acosta and Jorge Isaacs

International Nuclear Information System (INIS)

Castro Lopez, Pablo Antonio; Cardona Molina, Agustin

2010-01-01

The Sierra Nevada de Santa Marta, located in the northernmost part of Colombia, has been an object of scientific inquiry since at least the XIXth century, among other things because of its isolated character in relation to the Andean mountain chain. In this article we present some contributions to the knowledge of its origin and geological framework made by Joaquin Acosta (1800-1852) and Jorge Isaacs (1837-1895). Furthermore we establish a possible theoretical and conceptual relationship between these authors and some important European geologists and naturalists in the XIXth century, in the context of a history of ideas pertaining to orogenesis in Colombia.

Full Text Available The cocoa (Theobroma cacao L. based economyhas been considered a valid alternative to support sustainable development in northeastern Colombia. However, there is a lack of information about the cocoa production systems in the region which is needed for the implementation of effective plans to improve their performance and sustainability. Four of the main cocoa producing municipalities in the Norte de Santanderdepartment were considered for this study: Teorama, Bucarasica, Cúcuta and San Calixto. These entities were selected due to their adequate security conditions, availability of field assistants and departmental representativeness in cocoa production. The objective was to obtain basic information for local, specific and participatory actions for the sustainability of the cocoa production systems and to improve the living conditions of farmers. The methodology used was based on the farming system approach, considering the socioeconomic, technological and agro-ecologicalcomponents, and their relationships, and evaluating themaccording to the principles of sustainable agriculture. The phases covered were: (1 analysis of secondary data, (2 formulation and evaluation of sustainability indicators, (3 design, implementation and analysis of survey data and (4 validation by the farmers of the obtained information and the prioritization of problems. The results indicate that there is only one cocoa production system of a family-mercantile type, with low technology. Most farmers havelow incomes and basic needs such as health, education and public services are not met. They do not employ the agronomic and postharvest practices recommended by specialists. The water and soil resources are being degraded. In general, the farming system leans towards unsustainability and it is vital that integrative actions be taken to change this situation. / Se considera que el desarrollo de una economía basada en el cacao (Theobroma cacao L

Toxic phytoplankton in San Francisco Bay

Science.gov (United States)

Rodgers, Kristine M.; Garrison, David L.; Cloern, James E.

1996-01-01

The Regional Monitoring Program (RMP) was conceived and designed to document the changing distribution and effects of trace substances in San Francisco Bay, with focus on toxic contaminants that have become enriched by human inputs. However, coastal ecosystems like San Francisco Bay also have potential sources of naturally-produced toxic substances that can disrupt food webs and, under extreme circumstances, become threats to public health. The most prevalent source of natural toxins is from blooms of algal species that can synthesize metabolites that are toxic to invertebrates or vertebrates. Although San Francisco Bay is nutrient-rich, it has so far apparently been immune from the epidemic of harmful algal blooms in the world’s nutrient-enriched coastal waters. This absence of acute harmful blooms does not imply that San Francisco Bay has unique features that preclude toxic blooms. No sampling program has been implemented to document the occurrence of toxin-producing algae in San Francisco Bay, so it is difficult to judge the likelihood of such events in the future. This issue is directly relevant to the goals of RMP because harmful species of phytoplankton have the potential to disrupt ecosystem processes that support animal populations, cause severe illness or death in humans, and confound the outcomes of toxicity bioassays such as those included in the RMP. Our purpose here is to utilize existing data on the phytoplankton community of San Francisco Bay to provide a provisional statement about the occurrence, distribution, and potential threats of harmful algae in this Estuary.

2002-01-01

The Advanced Spaceborne Thermal Emission and Reflection radiometer, ASTER, is an international project: the instrument was supplied by Japan's Ministry of International Trade and Industry. A joint US/Japan science team developed algorithms for science data products, and is validating instrument performance. With its 14 spectral bands, extremely high spatial resolution, and 15 meter along-track stereo capability, ASTER is the zoom lens of the Terra satellite. The primary mission goals are to characterize the Earth's surface; and to monitor dynamic events and processes that influence habitability at human scales. ASTER's monitoring and mapping capabilities are illustrated by this series of images of the San Francisco area. The visible and near infrared image reveals suspended sediment in the bays, vegetation health, and details of the urban environment. Flying over San Francisco (3.2MB) (high-res (18.3MB)), we see the downtown, and shadows of the large buildings. Past the Golden Gate Bridge and Alcatraz Island, we cross San Pablo Bay and enter Suisun Bay. Turning south, we fly over the Berkeley and Oakland Hills. Large salt evaporation ponds come into view at the south end of San Francisco Bay. We turn northward, and approach San Francisco Airport. Rather than landing and ending our flight, we see this is as only the beginning of a 6 year mission to better understand the habitability of the world on which we live.

Jorge Juan and Antonio de Ulloa, naval officers of the Spanish Navy in the Midshipmen's Royal Academy were appointed to take part in one of the most important scientific expeditions of the 18th century. The question of the shape of the Earth, of vital importance for navigation, was solved by the Paris Academy of Sciences by request of Louis XV of France in 1735. The aim was to determine the form of the ellipsoid that Newton had described in the 17th century for any spherical and homogeneous body in rotation about an axis. Two expeditions were prepared for the geodetic measures of meridian arc both in high latitudes (Lapland, Finland) and in the equatorial zone (the Kingdom of Peru); Pierre Louis Maupertuis took charge of the northern expedition whereas the second one was charged to La Condamine, along with Jorge Juan and Antonio de Ulloa. The results obtained by the Spaniards were gathered in a publication: Observaciones astronómicas y físicas hechas en los Reinos del Perú. In it, they dedicate a chapter to the determination of astronomic longitude with the only technology that was providing certain precision at the moment: the simultaneous observation of the same astronomic phenomenon in two different places. Specifically, they explain in detail in Book III: Las Observaciones de la Inmersiones y Emersiones de los satélites de Júpiter, como asimismo de los eclipses de Luna; de las cuales de deduce la Longitud de los Lugares, incluyendo las correcciones a efectuar por la variación de la declinación diaria del Sol.

Argumenta que sus documentales, películas etnográficas y noticieros para el cine constituyen una totalidad discursiva que presenta estéticamente la producción del espacio estatal boliviano durante el siglo XX. A partir de una retórica audiovisual que juega con nociones de verticalidad, horizontalidad y centralidad, la obra de Ruiz posiciona el espacio andino como el eje de la modernización estatal y sitúa  a la cuenca amazónica en los márgenes del estado. Concluye que hacer visible la región amazónica en el discurso de la nación tuvo como efecto el desplazamiento de los antagonismos de clase en favor del conflicto entre centro y regiones.This article studies the cinematography of Jorge Ruiz making use of the socio-spatial theory of Henri Lefebvre. It argues that his documentaries, ethnographic films and newsreels for the cinema constitute a discursive totality that presents aesthetically the production of the Bolivian state space during the twentieth century. From an audiovisual rhetoric that plays with notions of verticality, horizontality and centrality, Ruiz’s work locates Andean space as the focal point of state modernization and situates the Amazon basin at the margins of the state. It concludes that in making the Amazon region visible in the nation’s discourse this had the effect of displacing class antagonisms in favor of the conflict between center and regions.

SANS studies of polymers

International Nuclear Information System (INIS)

Wignall, G.D.

1984-10-01

Before small-angle neutron scattering (SANS), chain conformation studies were limited to light and small angle x-ray scattering techniques, usually in dilute solution. SANS from blends of normal and labeled molecules could give direct information on chain conformation in bulk polymers. Water-soluble polymers may be examined in H 2 O/D 2 O mixtures using contrast variation methods to provide further information on polymer structure. This paper reviews some of the information provided by this technique using examples of experiments performed at the National Center for Small-Angle Scattering Research (NCSASR)

Modeling pesticide loadings from the San Joaquin watershed into the Sacramento-San Joaquin Delta using SWAT

2016-12-01

The Sacramento-San Joaquin Delta is an ecologically rich, hydrologically complex area that serves as the hub of California's water supply. However, pesticides have been routinely detected in the Delta waterways, with concentrations exceeding the benchmark for the protection of aquatic life. Pesticide loadings into the Delta are partially attributed to the San Joaquin watershed, a highly productive agricultural watershed located upstream. Therefore, this study aims to simulate pesticide loadings to the Delta by applying the Soil and Water Assessment Tool (SWAT) model to the San Joaquin watershed, under the support of the USDA-ARS Delta Area-Wide Pest Management Program. Pesticide use patterns in the San Joaquin watershed were characterized by combining the California Pesticide Use Reporting (PUR) database and GIS analysis. Sensitivity/uncertainty analyses and multi-site calibration were performed in the simulation of stream flow, sediment, and pesticide loads along the San Joaquin River. Model performance was evaluated using a combination of graphic and quantitative measures. Preliminary results indicated that stream flow was satisfactorily simulated along the San Joaquin River and the major eastern tributaries, whereas stream flow was less accurately simulated in the western tributaries, which are ephemeral small streams that peak during winter storm events and are mainly fed by irrigation return flow during the growing season. The most sensitive parameters to stream flow were CN2, SOL_AWC, HRU_SLP, SLSUBBSN, SLSOIL, GWQMN and GW_REVAP. Regionalization of parameters is important as the sensitivity of parameters vary significantly spatially. In terms of evaluation metric, NSE tended to overrate model performance when compared to PBIAS. Anticipated results will include (1) pesticide use pattern analysis, (2) calibration and validation of stream flow, sediment, and pesticide loads, and (3) characterization of spatial patterns and temporal trends of pesticide yield.

Full Text Available The aim of this study is to elucidate butterfly fauna in Mt. Gariwang-san, Korea. A field survey was conducted from 2010 to 2015 using the line transect method. A literature survey was also conducted. A total of 2,037 butterflies belonging to 105 species were recorded. In the estimation of species richness of butterfly, 116 species were estimated to live in Mt. Gariwang-san. In butterfly fauna in Mt. Gariwang-san, the percentage of northern species was very high and the percentage of grassland species was relatively higher than that of forest edge species and forest interior species. Sixteen red list species were found. In particular, Mimathyma nycteis was only recorded in Mt. Gariwang-san. When comparing the percentage of northern species and southern species including those recorded in previous studies, the percentage of northern species was found to have decreased significantly whereas that of southern species increased. We suggest that the butterfly community, which is distributed at relatively high altitudes on Mt. Gariwang-san, will gradually change in response to climate change.

Distribution and demography of San Francisco gartersnakes (Thamnophis sirtalis tetrataenia) at Mindego Ranch, Russian Ridge Open Space Preserve, San Mateo County, California

San Francisco gartersnakes (Thamnophis sirtalis tetrataenia) are a subspecies of common gartersnakes endemic to the San Francisco Peninsula of northern California. Because of habitat loss and collection for the pet trade, San Francisco gartersnakes were listed as endangered under the precursor to the Federal Endangered Species Act. A population of San Francisco gartersnakes resides at Mindego Ranch, San Mateo County, which is part of the Russian Ridge Open Space Preserve owned and managed by the Midpeninsula Regional Open Space District (MROSD). Because the site contained non-native fishes and American bullfrogs (Lithobates catesbeianus), MROSD implemented management to eliminate or reduce the abundance of these non-native species in 2014. We monitored the population using capture-mark-recapture techniques to document changes in the population during and following management actions. Although drought confounded some aspects of inference about the effects of management, prey and San Francisco gartersnake populations generally increased following draining of Aquatic Feature 3. Continued management of the site to keep invasive aquatic predators from recolonizing or increasing in abundance, as well as vegetation management that promotes heterogeneous grassland/shrubland near wetlands, likely would benefit this population of San Francisco gartersnakes.

Full Text Available A relação dialógica que há entre Sena e Camões é inegável e permite que se façam variadas incursões no que diz respeito ao diálogo entre eles. Por isso, investigar a leitura “maneirista” que Jorge de Sena faz acerca da obra camoniana e como ele entende ser uma obra de arte maneirista pode ajudar a crítica de ambos os autores a entender melhor a relação entre a poética deles, uma vez que, na esteira de Harold Bloom, acredito que dialogar é manter viva uma chama, é reconhecer a grandiosidade de um texto, dando-lhe presságios de ressurreição. A partir dessa leitura que proponho, é possível apontar em Sena pontos nodais de escrita que, inegavelmente, são devedores dos ensinamentos camonianos, como o humanismo, a problematização da condição moderna do sujeito, a subversão à ordem, a ética da escrita relacionada de maneira direta ao Outro.

Willingness to Pay for Dog Rabies Vaccine and Registration in Ilocos Norte, Philippines (2012).

The Philippines is one of the developing countries highly affected by rabies. Dog vaccination campaigns implemented through collaborative effort between the government and NGOs have played an important role in successfully reducing the burden of disease within the country. Nevertheless, rabies vaccination of the domestic animal population requires continuous commitment not only from governments and NGOs, but also from local communities that are directly affected by such efforts. To create such long-term sustained programs, the introduction of affordable dog vaccination and registration fees is essential and has been shown to be an important strategy in Bohol, Philippines. The aim of this study, therefore, was to estimate the average amount of money that individuals were willing to pay for dog vaccination and registration in Ilocos Norte, Philippines. This study also investigated some of the determinants of individuals' willingness to pay (WTP). A cross-sectional questionnaire was administered to 300 households in 17 municipalities (out of a total of 21) selected through a multi-stage cluster survey technique. At the time of the survey, Ilocos Norte had a population of approximately 568,017 and was predominantly rural. The Contingent Valuation Method was used to elicit WTP for dog rabies vaccination and registration. A 'bidding game' elicitation strategy that aims to find the maximum amount of money individuals were willing to pay was also employed. Data were collected using paper-based questionnaires. Linear regression was used to examine factors influencing participants' WTP for dog rabies vaccination and registration. On average, Ilocos Norte residents were willing to pay 69.65 Philippine Pesos (PHP) (equivalent to 1.67 USD in 2012) for dog vaccination and 29.13PHP (0.70 USD) for dog registration. Eighty-six per cent of respondents were willing to pay the stated amount to vaccinate each of their dogs, annually. This study also found that WTP was influenced by

Alameda County is located at the northern end of the Diablo Range of Central California. It is bounded on the north by the south flank of Mount Diablo, one of the highest peaks in the Bay Area, reaching an elevation of 1173 meters (3,849 ft). San Francisco Bay forms the western boundary, the San Joaquin Valley borders it on the east and an arbitrary line from the Bay into the Diablo Range forms the southern boundary. Alameda is one of the nine Bay Area counties tributary to San Francisco Bay. Most of the country is mountainous with steep rugged topography. Alameda County is covered by twenty-eight 7.5' topographic Quadrangles which are shown on the index map. The Quaternary deposits in Alameda County comprise three distinct depositional environments. One, forming a transgressive sequence of alluvial fan and fan-delta facies, is mapped in the western one-third of the county. The second, forming only alluvial fan facies, is mapped in the Livermore Valley and San Joaquin Valley in the eastern part of the county. The third, forming a combination of Eolian dune and estuarine facies, is restricted to the Alameda Island area in the northwestern corner of the county.

Small angle neutron scattering (SANS) has been a very powerful tool to study nanoscale (1-100 nm) bulk structures in various materials such as polymer, self assembled materials, nano-porous materials, nano-magnetic materials, metal and ceramics. Understanding the importance of the SANS instrument, the 8m SANS instrument was installed at the CN beam port of HANARO in 2001. However, without having a cold neutron source, the beam intensity is fairly low and the Q-range is rather limited due to short instrument length. In July 1, 2003, therefore, the HANARO cold neutron research facility project was launched and a state of the art 40m SANS instrument was selected as top-priority instrument. The development of the 40m SANS instrument was completed as a joint project between Korea Advanced Institute of Science and Technology and the HANARO in 2010. Here, we report the specification of a state of art 40m SANS instrument at HANARO

During this period we witness the implementation of a new ordo, or liturgical ritual that replaces the Hispanic one, strongly established in the Territorium. The liturgical adaptation produces tension and conflicts among the members of different monastic communities, and even between the Episcopate and the monarchy - being King Alfonso VI. In some of the monasteries, the arrival of the new ordo causes the adaptation of the liturgical space, with subsequent changes in liturgical furniture.

Full Text Available Una obra frecuentemente consultada por Jorge Luis Borges fue Matemáticas e imaginación, de E. Kasner y J. Newman, en la que se discute la teoría de los conjuntos (que es la rama de la matemática que estudia la relación entre conjuntos, propuesta por Georg Cantor (1845-1918, y mediante la cual se crea la aritmética transfinita (que va más allá de la finita y se establece un sistema epistémico para representar los diversos niveles del infinito. Así, Cantor le asigna a esas ininitudes la primera letra del alfabeto hebreo, el Aleph, seguido de un determinado número, dependiendo del nivel de infinitud (Aleph-cero, Aleph-uno, etc.. Borges, de esa manera, teje varias de sus narraciones en las que se trata el tema del ininito y del absoluto: un ejemplo de ello es la colección de relatos bajo el título El Aleph, que abre con el cuento «El inmortal» y cierra con el que le da el título a la colección. El presente ensayo tiene el propósito de estudiar «El inmortal» bajo la óptica cantoriana, para hablar de un absoluto en particular: el yo, y sugerir que no es posible establecer un vocabulario inal o una deinición deinitiva sobre el tema en cuestión. Tal imposibilidad, propone Borges, está dada en parte por la finitud lingüística, mientras que por otro lado la falibilidad de la memoria juega también un papel crucial en todo intento de deinición.

Full Text Available The 50,470 m2 the total area of the hospital is distributed as follows: 18,900 m2 for the 22 main clinics and for the additional clinics; 2,770 m2 for complementary activities; and the remaining 28,800 m2 for a parking lot with space for 700 cars. The building occupies a site that slopes strongly towards the north across which runs the pedestrian access from one of the circumference roads to the main façade; the access road for the vehicles leads to the back facade, where the natural slope of the ground has been taken advantage of to build the 5 storey parking building. The two main functions —the clinics and the parking house— are conveniently separated though connected with each other by means of corridors and lifts. The interior design of the clinics is very flexible so as to allow for further enlargements. The patients' waiting rooms are provided with a glazed façade and have a beautiful view over the San Francisco Bay and its surroundings. The construction is entirely of concrete and its structure is calculated ín such a manner as to allow for two additional storeys.Cuenta con una superficie total construida de 50.470 m2, repartidos de la siguiente forma: 18.900 se destinan a la distribución de 22 clínicas principales y otras secundarias; 2.770 a locales de actividades complementarias; y el resto, 28.800 m2, a aparcamiento con capacidad para 700 plazas. El edificio ocupa una parcela fuertemente inclinada hacia el norte, inclinación que permite el acceso peatonal a la clínica, por la fachada principal, desde una de las avenidas perimetrales; y el vehicular, por la fachada posterior, en donde, aprovechando el desnivel del terreno, se han organizado las cinco plantas del aparcamiento. Las dos funciones principales —clínicas y aparcamiento— se hallan convenientemente separadas, estableciéndose el enlace entre los distintos niveles mediante ascensores que relacionan las clínicas, el centro médico, los aparcamientos

Full Text Available Este texto realiza el retrato del líder político más importante de la primera parte del siglo XX en Colombia, el liberal Jorge Eliécer Gaitán, asesinado el 9 de abril de 1948, cuando la Presidencia de la República parecía estar a su alcance. Desde entonces, su fantasma acosó a una Colombia donde la violencia estalló y se mantuvo durante toda la segunda parte del siglo XX, con breves interrupciones. En este contexto, su trayectoria y pensamiento no dejaron de ser objetos de controversias y debates apasionados. El esfuerzo de clarifi cación conduce a reconocer la filiación populista del político colombiano. Es así como, a pesar de la ausencia de una experiencia populista duradera, el populismo tuvo un impacto central en la historia contemporánea del país andino. Las consecuencias de la presencia de esa ausencia son materia a reflexión sobre el resurgir de los populismos y el estancamiento democrático en la América latina contemporánea.

En la última década el cultivo de esta planta ha estado en crisis debido a los bajos precios del producto; sin embargo,los agricultores mantienen los cafetales como fuente de ingreso adoptando nuevas estrategias para obtener recursos económicos mediante la introducción o incremento de cultivos de importancia económica, como pimienta, mamey o plantas medicinales, aprovechando la versatilidad y posibilidades de reorganización de estos agroecosistemas. En este trabajo se presenta el inventario de la flora útil encontrada en cafetales de la SNP. A la fecha están registradas 319 especies pertenecientes a 238 géneros y 99 familias; 90 especies son objeto de comercio y pueden representar nuevas fuentes de ingreso; 256 son nativas y 63 introducidas y se han agrupado en 13 categorías antropocéntricas, de las cuales las medicinales y comestibles son las más numerosas.Coffee plantations in the Sierra Norte de Puebla (SNP are agroecosystems with variable composition and structure.

Conflictos sindicales en la maquila de la frontera norte

Cirila Quintero Ramírez

1999-01-01

Full Text Available El artículo analiza tres movimientos laborales en las maquiladoras de la frontera norte, acontecidos entre 1997 y 1998, señalando que más que eventos coyunturales, tales manifestaciones son parte de la reestructuración sindical iniciada en estas empresas durante los años setenta y ochenta. El comienzo de este proceso estuvo caracterizado por una definición de la función y los objetivos que estas organizaciones deberían desempeñar en estas industrias; así se conformaron dos comportamientos: el sindicalismo tradicional, vinculado a los trabajadores, y el sindicalismo subordinado, enlazado a los inversionistas. La segunda fase, iniciada a principios de los noventa, se ha caracterizado por un reacomodo en las estructuras internas de las organizaciones sindicales locales. En este reacomodo, la fragilidad de algunas organizaciones conformadas ex-profeso para las maquiladoras, como lo muestran los conflictos analizados, ha sido evidente.

Backwater Flooding in San Marcos, TX from the Blanco River

Earl, Richard; Gaenzle, Kyle G.; Hollier, Andi B.

2016-01-01

Large sections of San Marcos, TX were flooded in Oct. 1998, May 2015, and Oct. 2015. Much of the flooding in Oct. 1998 and Oct. 2015 was produced by overbank flooding of San Marcos River and its tributaries by spills from upstream dams. The May 2015 flooding was almost entirely produced by backwater flooding from the Blanco River whose confluence is approximately 2.2 miles southeast of downtown. We use the stage height of the Blanco River to generate maps of the areas of San Marcos that are lower than the flood peaks and compare those results with data for the observed extent of flooding in San Marcos. Our preliminary results suggest that the flooding occurred at locations more than 20 feet lower than the maximum stage height of the Blanco River at San Marcos gage (08171350). This suggest that the datum for either gage 08171350 or 08170500 (San Marcos River at San Marcos) or both are incorrect. There are plans for the U.S. Army Corps of Engineers to construct a Blanco River bypass that will divert Blanco River floodwaters approximately 2 miles farther downstream, but the $60 million price makes its implementation problematic.

"Sowing death in our women's wombs": modernization and indigenous nationalism in the 1960s Peace Corps and Jorge Sanjinés' "Yawar Mallku".

Science.gov (United States)

Geidel, Molly

2010-01-01

This paper explores the centrality of gender and sexual politics to both 1960s modernization discourses and anti-imperialist cultural nationalist ideologies through an analysis of Jorge Sanjinés' 1969 radical neorealist film Yawar Mallku, the text that led to the Peace Corps' expulsion from Bolivia. After outlining the development discourse that explicitly guided both the Peace Corps and the Revolutionary Nationalist (MNR) government of Bolivia and exploring the relationship of this discourse to the Bolivian radical and indigenous movements of the late 1960s, this paper reads Yawar Mallku in the context of these movements to arrive at an understanding how cultural nationalism in Bolivia became directed towards the developmentalist ideal of a masculine utopia whose construction would entail controlling women's bodies. Finally, the paper attempts to understand how indigenous women in Bolivia have articulated radical political visions within and in response to U.S. modernizing forces and indigenous cultural nationalism.

Holocene slip rates along the San Andreas Fault System in the San Gorgonio Pass and implications for large earthquakes in southern California

Science.gov (United States)

Heermance, Richard V.; Yule, Doug

2017-06-01

The San Gorgonio Pass (SGP) in southern California contains a 40 km long region of structural complexity where the San Andreas Fault (SAF) bifurcates into a series of oblique-slip faults with unknown slip history. We combine new 10Be exposure ages (Qt4: 8600 (+2100, -2200) and Qt3: 5700 (+1400, -1900) years B.P.) and a radiocarbon age (1260 ± 60 years B.P.) from late Holocene terraces with scarp displacement of these surfaces to document a Holocene slip rate of 5.7 (+2.7, -1.5) mm/yr combined across two faults. Our preferred slip rate is 37-49% of the average slip rates along the SAF outside the SGP (i.e., Coachella Valley and San Bernardino sections) and implies that strain is transferred off the SAF in this area. Earthquakes here most likely occur in very large, throughgoing SAF events at a lower recurrence than elsewhere on the SAF, so that only approximately one third of SAF ruptures penetrate or originate in the pass.Plain Language SummaryHow large are earthquakes on the southern San Andreas Fault? The answer to this question depends on whether or not the earthquake is contained only along individual fault sections, such as the Coachella Valley section north of Palm Springs, or the rupture crosses multiple sections including the area through the San Gorgonio Pass. We have determined the age and offset of faulted stream deposits within the San Gorgonio Pass to document slip rates of these faults over the last 10,000 years. Our results indicate a long-term slip rate of 6 mm/yr, which is almost 1/2 of the rates east and west of this area. These new rates, combined with faulted geomorphic surfaces, imply that large magnitude earthquakes must occasionally rupture a 300 km length of the San Andreas Fault from the Salton Sea to the Mojave Desert. Although many ( 65%) earthquakes along the southern San Andreas Fault likely do not rupture through the pass, our new results suggest that large >Mw 7.5 earthquakes are possible on the southern San Andreas Fault and likely

Full Text Available A Tuberculose é uma endemia de grande impacto na saúde pública brasileira, e o uso de mapas para análise da espacialização de indicadores torna-se uma importante ferramenta para subsidiar as ações de controle dessa doença. O objetivo desse estudo foi analisar a distribuição espacial dos casos novos de tuberculose pulmonar na região Norte do Brasil. Trata-se de um estudo ecológico que utiliza a distribuição espacial de dados secundários de casos novos de tuberculose diagnosticados em residentes nos municípios do Norte do Brasil nos anos de 2005 a 2010. Analisou-se os principais indicadores da doença. Foram diagnosticados 41.832 casos novos de Tuberculose; o estado do Amazonas registrou a maior incidência; 84,9% dos casos foram classificados como Tuberculose pulmonar; a taxa de letalidade foi de 5,43%. Os municípios com as maiores médias anuais de casos novos foram Manaus, Belém e Ananindeua. O percentual de co-infecção com o Vírus da Imunodeficiência Humana foi de 4,17%; 1533 casos foram registrados em menores de 15 anos. A taxa de cura foi menor que 85% em mais de 80% dos municípios. Os indicadores de Tuberculose na Região Norte do Brasil estão aquém das metas preconizadas pelo Ministério da saúde, apontando para a necessidade de implementação de políticas de saúde voltadas para populações residentes em áreas de maior risco.

Full Text Available At the end of 1925 the construction of Saint Jorge’s bridge began in Alcoy. This was one of the first large viaduct built entirely of reinforced concrete in Spain, but it also constitutes one of the unique overwhelming examples that the language of Art Deco used in its elements. The 90th anniversary of this bridge may serve to commemorate the success of a close collaboration between engineering and architecture. This viaduct had peculiar problems and important modifications during the construction that were resolved satisfactorily in a period of history where culture was heading towards modernity. In the present case, the work of the engineer and architect, duly selected by a shrewd and effective construction company in their building abilities, resulted in a magnificent forgotten structure that should be rehabilitated in the collective memory.

Full Text Available La falta de información de la erosividad de la lluvia en la Sierra Norte de Puebla, ha impedido una evaluación objetiva de su contribución al proceso de erosión. El presente trabajo se planteó como objetivo determinar el potencial erosivo y la variabilidad temporal de las precipitaciones en la Subcuenca del río San Marcos, a partir de diferentes índices que miden el grado de agresividad de las precipitaciones, así como establecer relaciones entre los mismos. Se utilizaron los registros pluviométricos de diez años de siete estaciones meteorológicas. Se calcularon los Índices de Fournier Anual (IFA, Modificado de Fournier (IMF, Concentración de Precipitaciones (ICP y Erosividad Total (IET. El estudio permite concluir que los riesgos de erosión son mayores en la zona de influencia de las estaciones climáticas de Xicotepec, Venustiano Carranza y Progreso, ubicadas en altitudes comprendidas entre 1279 y 886 msnm. Las precipitaciones según el ICP se concentran de manera estacional moderada de julio a octubre, y el IET evidencia que las precipitaciones presentan alta potencialidad erosiva. Los resultados fundamentarían el desarrollo de una estrategia agroecológica de conservación de suelos en función de la agresividad climática que presenta la zona de estudio

Cacao use and the San Lorenzo Olmec

Science.gov (United States)

Powis, Terry G.; Cyphers, Ann; Gaikwad, Nilesh W.; Grivetti, Louis; Cheong, Kong

2011-01-01

Mesoamerican peoples had a long history of cacao use—spanning more than 34 centuries—as confirmed by previous identification of cacao residues on archaeological pottery from Paso de la Amada on the Pacific Coast and the Olmec site of El Manatí on the Gulf Coast. Until now, comparable evidence from San Lorenzo, the premier Olmec capital, was lacking. The present study of theobromine residues confirms the continuous presence and use of cacao products at San Lorenzo between 1800 and 1000 BCE, and documents assorted vessels forms used in its preparation and consumption. One elite context reveals cacao use as part of a mortuary ritual for sacrificial victims, an event that occurred during the height of San Lorenzo's power. PMID:21555564

Susceptibility to mass movement processes in the municipality of Tlatlauquitepec, Sierra Norte de Puebla

Directory of Open Access Journals (Sweden)

Roberto Carlos Borja Baeza

2011-02-01

Full Text Available Since historical times, mass movement processes have taken place in the Mexican territory as a result of its topography, heterogeneous lithology, intense rainfall and the impact of anthropic activity, particularly in mountainous areas such as the Sierra Norte de Puebla. In this region, as a result of extremely high rainfall, a large number of landslides occurred in October 1999. These were mainly slides and flows; they affected economic, structural and environmental aspects and caused the loss of dozens of human lives. Among the various approaches to analysis of this type of hazard, cartography is of considerable importance since it allows the understanding and assessment of spatial distribution, as well as of the interactions of elements of the terrain that determine slope instability. Hence, some studies of landslide hazard cartography have been carried out in Mexico; these have mainly been based on the overlaying, against a background of geographic information systems, of layers of information concerning the parameters that are involved in slope instability. However, there is a tendency for this approach to establish similar degrees of influence for all factors, regardless of specific local conditions. The present aim was to consider the influence of the five most important parameters controlling regional slope instability in the Sierra Norte de Puebla (slope, morphogenesis, relief dissection, deforestation and roads, and to validate the results by means of a recurrence index. Multicriteria analysis has allowed a map of susceptibility to mass movement processes to be produced for the municipality of Tlatlauquitepec.

Distribution of 226Ra, 232Th, and 40K in soils of Rio Grande do Norte (Brazil)

International Nuclear Information System (INIS)

Malanca, A.; Pessina, V.; Dallara, G.

1996-01-01

A survey programme aimed at studying the environmental radioactivity in the Brazilian state of Rio Grande do Norte was undertaken. Fifty-two soil samples, together with two rock and two uraniferrous ore samples were collected from the eastern and central regions of this state. Concentrations of radioelements in samples were determined by γ-ray spectrometry. The average concentrations of 226 Ra, 232 Th, and 40 K in the surveyed soils were 29.2 ± 19.5 (SD), 47.8 ± 37.3, and 704 ± 437 Bq kg -1 , respectively. Higher values were found in the rock samples. The distributions of 226 Ra and 232 Th were fitted by log-normal curves. Radiological measurements carried out with a portable scintillometer at the sampled sites revealed an average absorbed dose rate of 55 ± 27 (SD) nGy h -1 . Computed dose rates obtained through the Beck formula ranged from 15-179 nGy h -1 , with a mean value of 72.6 ± 38.7 (SD) nGy h -1 , and their distribution fitted a log-normal curve. An annual average effective dose equivalent of 552 μSν (range: 117-1361 μSν) was estimated for 51 sites in Rio Grande do Norte. (author)

Marketing San Juan Basin gas

International Nuclear Information System (INIS)

Posner, D.M.

1988-01-01

Marketing natural gas produced in the San Juan Basin of New Mexico and Colorado principally involves four gas pipeline companies with significant facilities in the basin. The system capacity, transportation rates, regulatory status, and market access of each of these companies is evaluated. Because of excess gas supplies available to these pipeline companies, producers can expect improved take levels and prices by selling gas directly to end users and utilities as opposed to selling gas to the pipelines for system supply. The complexities of transporting gas today suggest that the services of an independent gas marketing company may be beneficial to smaller producers with gas supplies in the San Juan Basin

Full Text Available OBJETIVO: Comparar o uso de drogas entre os universitários e a população geral brasileira, assim como com os universitários norte-americanos, identificando possíveis diferenças de uso pela interferência da cultura. MÉTODOS: Para comparar o uso de drogas na vida entre as populações de interesse, foram utilizados os dados públicos de levantamentos estatísticos brasileiros realizados com universitários e a população geral, assim como levantamento estatístico norte-americano, por meio da comparação de intervalos de confiança (IC 95%. RESULTADOS: O uso de drogas na vida é mais frequente entre os estudantes norte-americanos, que relatam usar mais tabaco, tranquilizantes, maconha, ecstasy, alucinógenos, cocaína, crack e heroína que os universitários brasileiros. Em contrapartida, os universitários brasileiros relatam usar quase duas vezes mais inalantes do que os universitários norte-americanos. Esse padrão se repete ao se analisarem as diferenças intragênero. A isso se soma que os universitários brasileiros parecem envolver-se com mais frequência no uso de bebidas alcoólicas, maconha, tranquilizantes, inalantes, alucinógenos e anfetamínicos que seus pares da população geral brasileira. CONCLUSÕES: Conhecer as particularidades do uso de drogas entre os universitários é de suma importância para a detecção precoce desse consumo. Investimentos nesse segmento e diferenças de sexo devem ser contempladas nas políticas preventivas, assim como na elaboração de estratégias para a redução e o controle desse consumo, como programas de triagem e intervenção breve, uma vez que possuem a melhor relação custo-benefício.

Sulfide geochemical survey in Dawahan, Larap, Camarines Norte (Southern Luzon), Philippines

International Nuclear Information System (INIS)

Santos, G. Jr.

1979-07-01

Sulfide geochemical activation analysis survey was conducted in Southern Luzon, Philippines. Trace elements in the rocks of Dawahan, Larap, Camarines Norte, particularly in the sulfide fraction of the rocks were determined and correlated in the search for mineral deposits in the project area. The study has shown that the Cu, V, Co, Pb, Mn, Zn, Ni, Au, Ag and As distributions in Dawahan are log normal with Cu, As and V having an excess of low values. There is a direct relationship between the mineralizations of Ag and Pb with Cu mineralization. Fair geochemical correlations were observed between Cu-Zn, Cu-As and Cu-Co. Low negative or inverse correlation exists between Cu-Mn, Cu-V and Cu-Au. Silver is a good pathfinder for copper deposits in Dawahan and adjacent areas and most probably including the Paracale mining district

Full Text Available Green areas, also known as green infrastructure or urban vegetation, are vital to urbanites for their critical roles in mitigating urban heat island effects and climate change and for their provision of multiple ecosystem services and aesthetics. Here, I provide a high spatial resolution snapshot of the green cover distribution of the city of San Juan, Puerto Rico, by incorporating the use of morphological spatial pattern analysis (MSPA as a tool to describe the spatial pattern and connectivity of the city's urban green areas. Analysis of a previously developed IKONOS 4-m spatial resolution classification of the city of San Juan from 2002 revealed a larger area of vegetation (green areas or green infrastructure than previously estimated by moderate spatial resolution imagery. The city as a whole had approximately 42% green cover and 55% impervious surfaces. Although the city appeared greener in its southern upland sector compared to the northern coastal section, where most built-up urban areas occurred (66% impervious surfaces, northern San Juan had 677 ha more green area cover dispersed across the city than the southern component. MSPA revealed that most forest cover occurred as edges and cores, and green areas were most commonly forest cores, with larger predominance in the southern sector of the municipality. In dense, built-up, urban land, most of the green areas occurred in private yards as islets. When compared to other cities across the United States, San Juan was most similar in green cover features to Boston, Massachusetts, and Miami, Florida. Per capita green space for San Juan (122.2 m²/inhabitant was also comparable to these two U.S. cities. This study explores the intra-urban vegetation variation in the city of San Juan, which is generally overlooked by moderate spatial resolution classifications in Puerto Rico. It serves as a starting point for green infrastructure mapping and landscape pattern analysis of the urban green spaces

Sediment transport of streams tributary to San Francisco, San Pablo, and Suisun Bays, California, 1909-66

Porterfield, George

1980-01-01

A review of historical sedimentation data is presented, results of sediment-data collection for water years 1957-59 are summarized, and long-term sediment-discharge estimates from a preliminary report are updated. Comparison of results based on 3 years of data to those for the 10 water years, 1957-66, provides an indication of the adequacy of the data obtained during the short period to define the long-term relation between sediment transport and streamflow. During 1909-66, sediment was transported to the entire San Francisco Bay system at an average rate of 8.6 million cubic yards per year. The Sacramento and San Joaquin River basins provided about 83% of the sediment inflow to the system annually during 1957-66 and 86% during 1909-66. About 98% of this inflow was measured or estimated at sediment measuring sites. Measured sediment inflow directly to the bays comprised only about 40% of the total discharged by basins directly tributary to the bays. About 90% of the total sediment discharge to the delta and the bays in the San Francisco Bay system thus was determined on the basis of systematic measurements. (USGS)

Demand for woodfuels by households in the Province of Ilocos Norte, Philippines

Energy Technology Data Exchange (ETDEWEB)

Hyman, E

1985-12-01

This paper presents the results of a survey on woodfuel consumption conducted in the Province of Ilocos Norte, the Philippines. The survey examined household consumption of wood and other fuels such as coconut shells and husks, rice hulls and stems, bagasse, bamboo, animal dung, charcoal, kerosene, liquefied petroleum gas and electricity. The author describes the various pressures on the woodfuel supply in the province and patterns of consumption, collection and ways in which consumers are trying to compensate for their relatively high levels of fuelwood consumption by reafforestation and turning to other fuels. The author concludes with a number of policy options. These include an extensive tree planting program, the introduction of more fuel-efficient wood-stoves, and the increased substitution of other fuels such as bamboo or kerosene. 2 tables.

San Andreas tremor cascades define deep fault zone complexity

Science.gov (United States)

Shelly, David R.

2015-01-01

Weak seismic vibrations - tectonic tremor - can be used to delineate some plate boundary faults. Tremor on the deep San Andreas Fault, located at the boundary between the Pacific and North American plates, is thought to be a passive indicator of slow fault slip. San Andreas Fault tremor migrates at up to 30 m s-1, but the processes regulating tremor migration are unclear. Here I use a 12-year catalogue of more than 850,000 low-frequency earthquakes to systematically analyse the high-speed migration of tremor along the San Andreas Fault. I find that tremor migrates most effectively through regions of greatest tremor production and does not propagate through regions with gaps in tremor production. I interpret the rapid tremor migration as a self-regulating cascade of seismic ruptures along the fault, which implies that tremor may be an active, rather than passive participant in the slip propagation. I also identify an isolated group of tremor sources that are offset eastwards beneath the San Andreas Fault, possibly indicative of the interface between the Monterey Microplate, a hypothesized remnant of the subducted Farallon Plate, and the North American Plate. These observations illustrate a possible link between the central San Andreas Fault and tremor-producing subduction zones.

Hydrologic assessment and numerical simulation of groundwater flow, San Juan Mine, San Juan County, New Mexico, 2010–13

Stewart, Anne M.

2018-04-03

Coal combustion byproducts (CCBs), which are composed of fly ash, bottom ash, and flue gas desulfurization material, produced at the coal-fired San Juan Generating Station (SJGS), located in San Juan County, New Mexico, have been buried in former surface-mine pits at the San Juan Mine, also referred to as the San Juan Coal Mine, since operations began in the early 1970s. This report, prepared by the U.S. Geological Survey in cooperation with the Mining and Minerals Division of the New Mexico Energy, Minerals and Natural Resources Department, describes results of a hydrogeologic assessment, including numerical groundwater modeling, to identify the timing of groundwater recovery and potential pathways for groundwater transport of metals that may be leached from stored CCBs and reach hydrologic receptors after operations cease. Data collected for the hydrologic assessment indicate that groundwater in at least one centrally located reclaimed surface-mining pit has already begun to recover.The U.S. Geological Survey numerical modeling package MODFLOW–NWT was used with MODPATH particle-tracking software to identify advective flow paths from CCB storage areas toward potential hydrologic receptors. Results indicate that groundwater at CCB storage areas will recover to the former steady state, or in some locations, groundwater may recover to a new steady state in 6,600 to 10,600 years at variable rates depending on the proximity to a residual cone-of-groundwater depression caused by mine dewatering and regional oil and gas pumping as well as on actual, rather than estimated, groundwater recharge and evapotranspirational losses. Advective particle-track modeling indicates that the number of particles and rates of advective transport will vary depending on hydraulic properties of the mine spoil, particularly hydraulic conductivity and porosity. Modeling results from the most conservative scenario indicate that particles can migrate from CCB repositories to either the

2009-01-01

Chronic subdural hematomas (CSDHs) are basically treated by surgery. In some cases with no or minimum symptoms, however, they may be treated conservatively. In the present study, we evaluated the therapeutic effect of a Kampo medicine (Japanese traditional herbal medicine), Gorei-san, in the treatment of those CSDHs. Gorei-san 7.5 g t.i.d. was orally administered for 4 weeks in 22 patients with 27 CSDHs. Maximum thickness of the hematoma was followed up on CT scan for 4 to 29 weeks after administration of Gorei-san. In 7 of 22 patients, tranexamic acid and/or carbazochrome sodium sulfonate were also administrated. Gorei-san was effective in 23 of 27 CSDHs. In 12 of them, the hematoma was completely disappeared within 14 weeks after administration. In the other 11 CSDHs, the thickness was decreased. In those effective cases, thickness began to decrease 3 to 4 weeks after administration of Gorei-san. It was more effective in CSDHs with iso-/high or mixed density than with low density on CT. It was not effective in 4 out of 27 CSDHs. No apparent adverse effect was noted in the present series of patients. The present study suggests that a Kampo medicine, Gorei-san, is a useful option in the conservative treatment of CSDHs with no or minimum symptoms. (author)

Chemical and Physical Characteristics of Pulverized Granitic Rock Adjacent to the San Andreas, Garlock and San Jacinto Faults: Implications for Earthquake Physics

Science.gov (United States)

Rockwell, T. K.; Sisk, M.; Stillings, M.; Girty, G.; Dor, O.; Wechsler, N.; Ben-Zion, Y.

2008-12-01

We present new detailed analyses of pulverized granitic rocks from sections adjacent to the San Andreas, Garlock and San Jacinto faults in southern California. Along the San Andreas and Garlock faults, the Tejon Lookout Granite is pulverized in all exposures within about 100 m of both faults. Along the Clark strand of the San Jacinto fault in Horse Canyon, the pulverization of granitic rocks is highly asymmetric, with a much broader zone of pulverization along the southwest side of the Clark fault. In areas where the granite is injected as dyke rock into schist, only the granitic rock shows pulverization, demonstrating the control of rock type on the pulverization process. Chemical analyses indicate little or no weathering in the bulk of the rock, although XRD analysis shows the presence of smectite, illite, and minor kaolinite in the clay-sized fraction. Weathering products may dominate in the less than 1 micron fraction. The average grain size in all samples of pulverized granitic rock range between about 20 and 200 microns (silt to fine sand), with the size distribution in part a function of proximity to the primary slip zone. The San Andreas fault samples are generally finer than those collected from along the Garlock or San Jacinto faults. The particle size distribution for all samples is non-fractal, with a distinct slope break in the 60-100 micron range, which suggests that pulverization is not a consequence of direct shear. This average particle size is quite coarser than previous reports, which we attribute to possible measurement errors in the prior work. Our data and observations suggest that dynamic fracturing in the wall rock of these three major faults only accounts for 1% or less of the earthquake energy budget.

Full Text Available Los miembros del equipo de cooperación internacional "Territorio Andaluz, Desarrollo e Innovación" se han implicado durante más de una década en proyectos de desarrollo sobre zonas colindantes con el Estrecho de Gibraltar. En este artículo se resume el perfil y las conclusiones obtenidas en los proyectos de cooperación desarrollados por el grupo, así como otros hechos relacionados con las transformaciones territoriales del Norte de Marruecos. En la actualidad, las acciones se basan en la construcción de grandes puertos y carreteras cercanas a los nuevos centros turísticos de la costa. Los impactos son evidentes en el medio ambiente y en el contexto social. La transformación radical ha aumentado el atractivo en las zonas urbanas, incrementando el éxodo rural que ya era de por sí considerable. Por otra, la pérdida de calidad de vida la asociamos a la merma de suelo cultivable y el deterioro del medio al poner en cultivo tierras forestales. La agricultura es de subsistencia y como tal está sometida a la supervivencia de las familias en un medio cada vez más desfavorable. Las intervenciones en este medio podrían tomar como ejemplo los patrones que se han aplicado en el entorno rural español en el pasado, cuyo deterioro siguió pautas similares en un período de tiempo más largo.

Full Text Available En el presente estudio se compara la abundancia y riqueza entre los roedores nocturnos de un zacatal gipsófilo y los de 3 matorrales micrófilos, en el norte de San Luis Potosí. Los muestreos se llevaron a cabo en sitios con distintas características edáficas y de estructura de la vegetación, en la estación lluviosa y en la seca de los años 2003 y 2004. Como estimador del tamaño poblacional se utilizó el número de individuos capturados en cada periodo. Se capturaron 414 individuos de 12 especies de las familias Heteromyidae y Muridae. Se concluye que: 1 las comunidades de roedores en cada sitio fueron diferentes en función de la estructura vegetal y cambiaron de manera notable entre el zacatal y los 3 sitios de matorral adyacentes; 2 dichas comunidades reflejaron el mosaico de la vegetación más que la época del año; 3 los tres tipos de matorral mantuvieron su identidad individual a lo largo del año, y 4 la baja precipitación y/o el pastoreo, a través de la reducción de la cobertura vegetal sobre suelos gipsófilos afectó a los roedores.In this study we compared abundance and species richness of nocturnal rodents at the edge of gypsophilous grassland on an exposed gypsum substrate and 3 sites of microphilous shrubland, in northern San Luis Potosí, Mexico. We sampled at sites that differed in edaphic characteristics and vegetation structure, in the wet and dry seasons of 2003 and 2004. As a population estimator we used the number of individuals captured in each sampling period. We captured 414 individuals of 12 species of Heteromyidae and Muridae. We concluded that 1 rodent communities were different among sites as a function of vegetation structure, and varied notably between grassland and adjacent shrublands: 2 such communities reflected the vegetation mosaic more than season of the year: 3 the three shrubland types maintained their identity throughout the year; y 4 low precipitation and/or grazing, through the reduction of

San Juanico is a fishing village of approximately 120 homes in the Municipality of Comondu, Baja California. In April, 1999, a hybrid power system was installed in San Juanico to provide 24-hour power, which was not previously available. Before the installation of the hybrid power system, a field study was conducted to characterize the electrical usage and institutional and social framework of San Juanico. One year after the installation of the hybrid power system a''post-electrification'' study was performed to document the changes that had occurred after the installation. In December of 2003, NREL visited the site to conduct a technical assessment of the system.

Estimating natural recharge in San Gorgonio Pass watersheds, California, 1913–2012

Science.gov (United States)

Hevesi, Joseph A.; Christensen, Allen H.

2015-12-21

A daily precipitation-runoff model was developed to estimate spatially and temporally distributed recharge for groundwater basins in the San Gorgonio Pass area, southern California. The recharge estimates are needed to define transient boundary conditions for a groundwater-flow model being developed to evaluate the effects of pumping and climate on the long-term availability of groundwater. The area defined for estimating recharge is referred to as the San Gorgonio Pass watershed model (SGPWM) and includes three watersheds: San Timoteo Creek, Potrero Creek, and San Gorgonio River. The SGPWM was developed by using the U.S. Geological Survey INFILtration version 3.0 (INFILv3) model code used in previous studies of recharge in the southern California region, including the San Gorgonio Pass area. The SGPWM uses a 150-meter gridded discretization of the area of interest in order to account for spatial variability in climate and watershed characteristics. The high degree of spatial variability in climate and watershed characteristics in the San Gorgonio Pass area is caused, in part, by the high relief and rugged topography of the area.

A simulation of the San Andreas fault experiment

Agreen, R. W.; Smith, D. E.

1974-01-01

The San Andreas fault experiment (Safe), which employs two laser tracking systems for measuring the relative motion of two points on opposite sides of the fault, has been simulated for an 8-yr observation period. The two tracking stations are located near San Diego on the western side of the fault and near Quincy on the eastern side; they are roughly 900 km apart. Both will simultaneously track laser reflector equipped satellites as they pass near the stations. Tracking of the Beacon Explorer C spacecraft has been simulated for these two stations during August and September for 8 consecutive years. An error analysis of the recovery of the relative location of Quincy from the data has been made, allowing for model errors in the mass of the earth, the gravity field, solar radiation pressure, atmospheric drag, errors in the position of the San Diego site, and biases and noise in the laser systems. The results of this simulation indicate that the distance of Quincy from San Diego will be determined each year with a precision of about 10 cm. Projected improvements in these model parameters and in the laser systems over the next few years will bring the precision to about 1-2 cm by 1980.

El complejo vial Ulisses de Góis ubicado en la porción Norte de la capital potiguar está compuesto por el Puente Ulisses de Góis, más conocido como Puente de Igapó, el cual fue durante más de tres décadas la única conexión entre la porción Norte con el resto de la ciudad y por el Viaducto Ulisses de Góis, concluido en 2002, el que interconecta el Puente de Igapó con otras relevantes arterias de esta Zona administrativa natalense. Con la construcción de este último componente viario, ocurrieron profundas dinámicas en el sistema de tránsito, no solamente en la Zona Norte como el de la capital potiguar. De esta forma, la presente investigación pretendió comprender la influencia del complejo vial en las dinámicas impuestas en el sistema de tránsito y en las propias configuraciones urbanas de la capital potiguar, y las posibles mejoras (o no traídas por esta obra vial para la fluencia de los vehículos automotores. Por lo tanto, a través de investigaciones bibliográficas e investigaciones de campo, realizada con la aplicación de cuestionarios estructurados a usuarios y residentes del área en cuestión, se observó que: a pesar de la considerable proporción de los usuarios (48% que afirman que ocurrió una significativa mejora en el tránsito de la zona, en el norte con la construcción del Viaducto Ulisses de Góis, una parte no menos importante (37%, considera que el impacto de la construcción del viaducto para la fluidez del tránsito fue insignificante, pues no contribuyó a la resolución de los problemas de circulación de los vehículos. Se percibió, que se hace necesario dotar a la ciudad de una planificación volcada hacia su realidad, con el objetivo de aumentar aún más la fluidez del tránsito en la capital potiguar, a través de medidas como el incremento del transporte de masa, posibilitando aún más la movilidad urbana y, así, constituyendo una ciudad más justa e igualitaria para todos los natalenses.

A globalização vista do norte e do sul: quais os seus mecanismos sociais?

Directory of Open Access Journals (Sweden)

Olivier Giraud

Full Text Available Procura-se, neste artigo, definir a globalização a partir da identificação de uma série de mecanismos sociais por meio dos quais essa age diretamente sobre os comportamentos individuais e coletivos ou ainda sobre a maneira de pensar, as crenças, as identidades, as formas de institu-cionalização, etc. O que constitui a especificidade da globalização é justamente o fato de ser um fenômeno social que se manifesta em todo o planeta. Será que os mecanismos específicos que caracterizam o funcionamento da globalização são aplicáveis nas mesmas condições nas sociedades que apresentam fortes diferenças como é o caso das sociedades do Norte e do Sul? Diferentes mecanismos ligados ao reforço da competição econômica internacional e às suas conseqüências sobre o sistema de proteção social, ou ainda ligados à difusão de normas e de práticas políticas no contexto da globalização, serão abordados em seguida. De forma mais sistemática, quatro cenários convergência, divergência, hibridação e recomposição das hierarquias internacionais serão apresentados no contexto de uma análise comparativa dos efeitos da globalização nas sociedades do Sul e do Norte.

Full Text Available Los hallazgos arqueológicos en la costa norte peruana durante las últimas décadas han permitido constatar que el género femenino tuvo un peso muy importante en las estructuras regionales de poder. Se ha descubierto que las mujeres ocuparon cargos especiales en el mundo político-religioso, lo cual significa una importante contribución al actual análisis de la sociedad prehispánica en la costa norte del Perú. Este artículo analiza cuatro de estos cargos ocupados por mujeres de élite y argumenta que, posiblemente, tengan una vinculación directa entre ellos mediante un fuerte sentido de espiritualidad donde los mundos político, religioso y social aparecen fuertemente vinculados.   Archaeological findings on the Northern coast of Peru in recent decades, have allowed for bringing to light the important role played by women in the power structures in the coast. The acknowledgement that women occupied special positions in the political and religious worlds, means a significant contribution to the current analysis of pre-Hispanic society in the Northern coast of Peru. Therefore, this article looks at four of these positions occupied by elite women, and argues that they may be intertwined by means of a strong sense of spirituality in which the political, the religious and the social worlds can't be dissociated from one another.

The band grapples with the ways by which a dominant U.S. national discourse has historically subordinated Mexican migrant and Chicano/a communities. Through t...

The instrument SANS-1 at the Geesthacht neutron facility GeNF was used for scattering experiments in 2000 at 196 of 200 days of reactor and cold source operation. The utilisation was shared between the in-house R and D program and user groups from different universities and research centers. These measurements were performed and analysed either by guest scientists or GKSS staff. The focus of the work in 2000 at the experiment SANS-1 was the structural investigation of hydrogen containing substances such as biological macromolecules (ribosomes, protein-RNA-complexes, protein solutions, glycolipids and membranes), molecules which are important in the fields of environmental research (refractoric organic substances) and technical chemistry (surfactants, micelles).

We report on SANS measurements carried out on the instrument SANS1 (V4) at the BENSC facility on solutions and composites of cellulose tricarbanilate (CTC). This cellulose derivative exhibits lyotropic behaviour in methylacrylate (MA). The SANS data indicate that in the isotropic liquid state (up to 25% wt CTC in MA) the CTC chains behave like rods of mass per unit length (M/L). In the liquid crystalline (LC) phase (at and above 35% wt CTC in MA), the Q dependence varies from Q sup - sup 1 to Q sup - sup 4 , probably as a result of self-assembling of the CTC chains. The general aim of our work is to prepare molecular composites, i.e. miscible blends of rigid-rod and flexible-coil polymers, from CTC solutions in polymerizable media. To establish the degree of homogeneity of the composites, we performed SANS measurements on UV-cured CTC/MA solutions. Here, we compare the SANS data of CTC/monomer solutions with those of the corresponding composites. (orig.)

Contemporary in situ tectonic stress indicators along the San Andreas fault system in central California show northeast-directed horizontal compression that is nearly perpendicular to the strike of the fault. Such compression explains recent uplift of the Coast Ranges and the numerous active reverse faults and folds that trend nearly parallel to the San Andreas and that are otherwise unexplainable in terms of strike-slip deformation. Fault-normal crustal compression in central California is proposed to result from the extremely low shear strength of the San Andreas and the slightly convergent relative motion between the Pacific and North American plates. Preliminary in situ stress data from the Cajon Pass scientific drill hole (located 3.6 kilometers northeast of the San Andreas in southern California near San Bernardino, California) are also consistent with a weak fault, as they show no right-lateral shear stress at approximately 2-kilometer depth on planes parallel to the San Andreas fault.

The San Miguel volcano lies near the city of San Miguel, El Salvador (13.43N and -88.26W). San Miguel volcano, an active stratovolcano, presents a significant natural hazard for the city of San Miguel. Furthermore, the internal state and activity of volcanoes remains an important component to understanding volcanic hazard. The main technology for addressing volcanic hazards and processes is through the analysis of data collected from the deployment of seismic sensors that record ground motion. Six UTEP seismic stations were deployed around San Miguel volcano from 2007-2008 to define the magma chamber and assess the seismic and volcanic hazard. We utilize these data to develop images of the earth structure beneath the volcano, studying the volcanic processes by identifying different sources, and investigating the role of earthquakes and faults in controlling the volcanic processes. We will calculate receiver functions to determine the thickness of San Miguel volcano internal structure, within the Caribbean plate. Crustal thicknesses will be modeled using calculated receiver functions from both theoretical and hand-picked P-wave arrivals. We will use this information derived from receiver functions, along with P-wave delay times, to map the location of the magma chamber.
