PWV FORECAST VALIDATION AT ALMA SITE
D. Pozo,L. Illanes,M. Caneo,M. Curu00E9
Revista mexicana de astronomía y astrofísica , 2011,
Abstract: En este estudio se implementó el modelo WRF (Weather Research and Forecasting) y se evaluó su sensibilidad con el fin de pronosticar las condiciones atmosféricas, principalmente el vapor de agua precipitable (en inglés, PWV) en el sitio de ALMA (Atacama Large Millimeter/Submillimeter Array). Se evaluaron 5 configuraciones del WRF con diferentes opciones físicas de capa límite, de modelo de suelo y microfísica, que fueron comparadas con datos observados de radiómetro y estación meteorológica, entre abril y diciembre de 2007. Los resultados mostraron que todas las simulaciones sobrestiman los valores de PWV, particularmente en los meses de verano. Además, los cambios de parametrización de microfísica no influyen significativamente en el pronóstico, observándose mejores resultados con el modelo de suelo Noah. Los menores errores fueron obtenidos con la configuración YSU-Noah, sugiriendo ser apropiada para usarse en el pronóstico operativo de PWV en ALMA.
A COMPARISON BETWEEN SOUNDING DATA AND WRF FORECASTS AT APEX SITE
M. Caneo,D. Pozo,L. Illanes,M. Curu00E9
Revista mexicana de astronomía y astrofísica , 2011,
Abstract: Cinco configuraciones de WRF usando diferentes modelos de suelo y parametrizaciones de microfísica y de capa límite planetaria se evaluaron con sondeos lanzados durante una campa a de mediciones en el sitio de APEX (Atacama Pathfinder EXperiment). Los resultados indican que los cambios en la parametrización de microfísica no producen cambios apreciables en los perfiles de humedad. El modelo de suelo de Noah muestra menores errores en los perfiles verticales de las variables analizadas en comparación con el esquema de difusión térmica de 5 capas. El análisis de condiciones sin ópticas mostró que las dificultades en predecir la variación diurna en la dirección del viento en condiciones de buen tiempo y la aparición de capas secas poco profundas en la atmósfera son algunas fuentes de errores en los pronósticos.

Abstract: Presentar las ventajas de la secuencia IDEAL (Iterative Decomposition of water and fat with Echo Asymmetry and Least-squares estimation) en la evaluación de los nervios periféricos y plexos braquial (PB) y lumbosacro (PLS) para el diagnóstico de las neuropatías por atrapamiento o compresión, las neuropatías sin atrapamiento y las condiciones subyacentes. La secuencia IDEAL proporciona 4 tipos de imágenes a partir de una sola adquisición, permitiendo la supresión uniforme de la grasa y el agua, y la obtención de imágenes en fase o fuera de fase de agua, grasa o de la combinación de éstas. Materiales y Métodos. Estudio retrospectivo de enero de 2011 a junio de 2011. Se realizaron 11 neurografías con secuencia IDEAL en resonancia magnética 3T (HDX 3T, GE Healthcare, USA), con bobinas phased array de 8 canales en planos coronal y sagital, cortes de 1,2 - 0 mm, y plano axial 3D spoiled gradient recalled (SPGR) T1, cortes 1 - 0 mm sin y con gadolinio. El campo de visión (FOV) fue variable según el nervio o plexo a explorar. Resultados. Se encontraron 2 schwannomas (plexo braquial, nervio ciático), 1 neuritis (inflamación por compresión del nervio mediano), 2 casos con neurofibromas múltiples (uno en plexo lumbosacro y ciático y otro en plexo braquial), 3 neuromas postraumáticos (ciático poplíteo externo -CPE-), una avulsión con pseudomeningocele (plexo braquial) y 2 casos sin alteraciones (plexo lumbosacro y ciático poplíteo externo). Conclusión. En esta presentación preliminar, la neurografía por resonancia magnética (RM) mostró una excelente diferenciación entre el nervio y las estructuras circundantes y permitió reconocer la estructura del nervio y su se al, determinar variantes anatómicas y causas de neuropatías, así como también se pudieron evaluar los cambios de denervación en los grupos musculares involucrados. Purpose. Demonstrate the advantages of the IDEAL (Iterative Decomposition of water and fat with Echo Asymmetry and Least-squares estimation) sequence in the evaluation of peripheral nerves, brachial plexus and lumbar plexus, for the diagnosis of compression or entrapment neuropathies, non-entrapment neuropathies, and the underlying conditions. The IDEAL sequence provides 4 types of images from a single acquisition, allowing uniform fat or water suppression and in phase/out of phase images of water, fat or a combination of both. Materials and Methods. This is a retrospective study, from January 2011 to June 2011. Eleven neurographies were performed on 3T MRI (HDX 3T, GE Healthcare, USA), with 8-channel phased array coils on sagittal and coronal pl

Abstract: OBJETIVO: Um dispositivo de bandagem do tronco pulmonar (TP) com ajuste percutaneo foi desenvolvido com o objetivo de induzir a hipertrofia rápida do ventrículo subpulmonar. MATERIAL E MéTODOS: Consiste de um manguito de silicone insuflável percutaneamente, através de um bot o de silicone auto-selante. Os cora es de 7 cabritos jovens (peso médio: 8,7 kg) foram submetidos à sobrecarga sistólica imposta pelo dispositivo e avaliados sob os aspectos hemodinamicos, ecocardiográficos e morfológicos. Foram extraídas biópsias basais do miocárdio do ventrículo direito (VD) para análise microscópica (perímetro e área do miócito). O dispositivo foi implantado no TP. As press es do VD, TP e aorta foram monitorizadas. Após convalescen a, foi iniciado o protocolo de insufla o do dispositivo de bandagem do TP. Foi injetada água destilada no bot o auto-selante (via percutanea), até que a press o sistólica do VD atingisse 70% da press o sistólica do VE. As avalia es ecocardiográfica e hemodinamica foram realizadas a cada 24 horas. A sobrecarga sistólica do VD foi mantida por um período de 96 horas, com insufla es progressivas no limite máximo tolerado, a cada 24 horas. Após esse período, os animais foram sacrificados para análise morfológica dos cora es. Outros 9 cabritos (peso médio: 7,7 kg) foram utilizados como grupo controle, para análise do peso do VD. RESULTADOS: Após 96 horas de sobrecarga sistólica do VD, foi observado um aumento do gradiente sistólico VD/TP de 10,1±4,3 mmHg para 60,0±11,0 mmHg e da press o sistólica no VD de 22,4±4,1 mmHg para 71,0±10,0 mmHg (p<0,0001). O ecocardiograma revelou aumento da espessura muscular do VD, de 4,4±0,5 mm para 7,3±1,7 mm (p=0,001). Quando comparado ao grupo controle, houve um ganho de peso de 74% do VD submetido à sobrecarga sistólica (p<0,0001). à microscopia óptica, foi observado aumento de 27% no perímetro e de 69% na área dos miócitos (p=0,0001). CONCLUS ES: O dispositivo proposto neste trabalho é efetivo e facilmente ajustável por via percutanea, possibilitando a hipertrofia do ventrículo subpulmonar em 96 horas de sobrecarga sistólica. A melhora na ajustabilidade da bandagem do TP poderá permitir melhores resultados da opera o de Jatene em dois estágios, nos pacientes com transposi o das grandes artérias.

Abstract: background: the increasing number of children with evolving congenital heart diseases demands greater preparation of professionals and institutions that handle them. objective: to describe the profile of patients aged over 16 years with congenital heart disease, who have undergone surgery, and analyze the risk factors that predict hospital mortality. method: one thousand five hundred twenty patients (mean age 27 ± 13 years) were operated between january 1986 and december 2010. we performed a descriptive analysis of the epidemiological profile of the study population and analyzed risk factors for hospital mortality, considering the complexity score, the year in which surgery was performed, the procedure performed or not performed by the pediatric surgeon and reoperation. results: there was a significant increase in the number of cases from the year 2000. the average complexity score was 5.4 and the septal defects represented 45% of cases. overall mortality was 7.7% and most procedures (973 or 61.9%) with greater complexity were performed by pediatric surgeons. complexity (or 1.5), reoperation (or 2.17) and pediatric surgeon (or 0.28) were independent risk factors influencing mortality. multivariate analysis showed that the year in which the surgery was performed (or 1.03), the complexity (or 1.44) and the pediatric surgeon (or 0.28) influenced the result. conclusion: there is an increasing number of patients aged 16 years which, despite the large number of simple cases, the most complex ones were referred to pediatric surgeons, who had lower mortality, especially in recent years.
