Los Topónimos, Su Manejo Mediante Sig y Sus Aplicaciones en Cartografía
Fil: Asato, C.G. Servicio Geológico Minero Argentino; Argentina. ORCID: 0000-0002-1968-7741Fil: Wright, E.M. Servicio Geológico Minero Argentino; Argentina.Este trabajo fue presentado en el Segundo Congreso de la Ciencia Cartográfica - IX Semana Nacional de la Cartografía-2004Tradicionalmente en una composición cartográfica digital, los topónimos han sido manejados como
elementos gráficos, a través de su edición manual, de su definición como caracteres alfanuméricos y de sus
características gráficas. Con el advenimiento de los SIG este proceso se ha agilizado, y en ciertos aspectos
automatizado, a través del etiquetado por consulta a la base de datos de atributos de las distintas capas de
información.
Este procedimiento, que en la mayoría de los casos ha demostrado ser sencillo y eficaz, encuentra
una limitación importante cuando se trata de manejar topónimos distribuidos en varias capas de información
o cuando se da el caso común de que los datos de nombres son incompletos o se carece de la capa de
información pertinente. El manejo de topónimos en estas condiciones complica la composición cartográfica,
dado el trabajo intensivo de compaginación y armonización que es necesario realizar.
En este trabajo se propone el manejo unificado y estructurado de los topónimos mediante la
construcción de una única base de datos. Esta cuenta con un diseño especial que permite tanto la consulta
por palabras claves o por áreas geográficas, como el despliegue de los textos en mapas de distinto tipo y a
distintas escalas, aplicando para esto metodologías de selección, definición de patrones de texto y
generalización. Se describe la estructura de la base de datos, y se explican sus ventajas como una solución
sencilla de manejo de los textos, de edición y de producción cartográfica

Servicio Geológico Minero Argentino. Instituto de Geología y Recursos Minerales; Argentina.El Complejo volcánico Nevados de Chillán (CVNC) corresponde a un complejo volcánico de forma elíptica, de composición que varía entre dacítica a andesítica. Se ubica en la cordillera andina de la Región de Ñuble, en el límite de las comunas de Coihueco y Pinto, Chile.
El CVNC permanece en el contexto de un proceso eruptivo de explosividad pulsátil y efusión de flujos de lava, coexistencia que sugiere diferentes características geológicas y dinámicas en el sistema de los conductos volcánicos.
El Observatorio Argentino de Vigilancia Volcánica (OAVV) considera que todo nivel de afectación registrado se mantiene en territorio chileno, sobre los sectores cercanos al cráter del volcán. Sin embargo, podría registrarse eventualmente la presencia de ceniza volcánica en suspensión sobre la frontera entre Argentina y Chile, sin que esta genere afectación directa sobre alguna población argentina.
El OAVV destaca que, con este escenario, solamente ante un eventual proceso eruptivo mayor, podría registrarse caída de ceniza sobre poblaciones argentinas, generando algún tipo de afectación directa.
Por tal motivo y de forma preventiva, el Observatorio Volcanológico de los Andes del Sur (OVDAS) de Chile mantiene el nivel de alerta técnica, mientras que el OAVV permanecerá en constante comunicación con OVDAS informando sobre cambios en la actividad del volcán y cualquier posible afectación sobre territorio Argentino1.
Por lo expresado con anterioridad, se decidió realizar un análisis complementario al que realiza el OAVV, con el fin de identificar deformación superficial en el CVNC. Para este fin, se utilizaron imágenes satelitales de radar del sensor Sentinel− 1 a las cuales se les aplicaron diferentes técnicas InSAR (Synthetic Aperture Radar Interferometry)

Observation of the B0 → ρ0ρ0 decay from an amplitude analysis of B0 → (π+π−)(π+π−) decays
Proton–proton collision data recorded in 2011 and 2012 by the LHCb experiment, corresponding to an integrated luminosity of 3.0 fb−1 , are analysed to search for the charmless B0→ρ0ρ0 decay. More than 600 B0→(π+π−)(π+π−) signal decays are selected and used to perform an amplitude analysis, under the assumption of no CP violation in the decay, from which the B0→ρ0ρ0 decay is observed for the first time with 7.1 standard deviations significance. The fraction of B0→ρ0ρ0 decays yielding a longitudinally polarised final state is measured to be fL=0.745−0.058+0.048(stat)±0.034(syst) . The B0→ρ0ρ0 branching fraction, using the B0→ϕK⁎(892)0 decay as reference, is also reported as B(B0→ρ0ρ0)=(0.94±0.17(stat)±0.09(syst)±0.06(BF))×10−6
Measurement of the (eta c)(1S) production cross-section in proton-proton collisions via the decay (eta c)(1S) -> p(p)over-bar
