Identification of tsunami-induced deposits using numerical modeling and rock magnetism techniques: A study case of the 1755 Lisbon tsunami in Algarve, Portugal

Storm- and tsunami-deposits are generated by similar depositional mechanisms making their discrimination hard to establish using classic sedimentologic methods. Here we propose an original approach to identify tsunami-induced deposits by combining numerical simulation and rock magnetism. To test our method, we investigate the tsunami deposit of the Boca do Rio estuary generated by the 1755 earthquake in Lisbon which is well described in the literature. We first test the 1755 tsunami scenario using a numerical inundation model to provide physical parameters for the tsunami wave. Then we use concentration (MS. SIRM) and grain size (chi(ARM), ARM, B1/2, ARM/SIRM) sensitive magnetic proxies coupled with SEM microscopy to unravel the magnetic mineralogy of the tsunami-induced deposit and its associated depositional mechanisms. In order to study the connection between the tsunami deposit and the different sedimentologic units present in the estuary, magnetic data were processed by multivariate statistical analyses. Our numerical simulation show a large inundation of the estuary with flow depths varying from 0.5 to 6 m and run up of similar to 7 m. Magnetic data show a dominance of paramagnetic minerals (quartz) mixed with lesser amount of ferromagnetic minerals, namely titanomagnetite and titanohematite both of a detrital origin and reworked from the underlying units. Multivariate statistical analyses indicate a better connection between the tsunami-induced deposit and a mixture of Units C and D. All these results point to a scenario where the energy released by the tsunami wave was strong enough to overtop and erode important amount of sand from the littoral dune and mixed it with reworked materials from underlying layers at least 1 m in depth. The method tested here represents an original and promising tool to identify tsunami-induced deposits in similar embayed beach environments.

Monte Carlo modeling and simulations of the High Definition (HD120) micro MLC and validation against measurements for a 6 MV beam

Purpose: The most recent Varian® micro multileaf collimator(MLC), the High Definition (HD120) MLC, was modeled using the BEAMNRCMonte Carlo code. This model was incorporated into a Varian medical linear accelerator, for a 6 MV beam, in static and dynamic mode. The model was validated by comparing simulated profiles with measurements. Methods: The Varian® Trilogy® (2300C/D) accelerator model was accurately implemented using the state-of-the-art Monte Carlo simulation program BEAMNRC and validated against off-axis and depth dose profiles measured using ionization chambers, by adjusting the energy and the full width at half maximum (FWHM) of the initial electron beam. The HD120 MLC was modeled by developing a new BEAMNRC component module (CM), designated HDMLC, adapting the available DYNVMLC CM and incorporating the specific characteristics of this new micro MLC. The leaf dimensions were provided by the manufacturer. The geometry was visualized by tracing particles through the CM and recording their position when a leaf boundary is crossed. The leaf material density and abutting air gap between leaves were adjusted in order to obtain a good agreement between the simulated leakage profiles and EBT2 film measurements performed in a solid water phantom. To validate the HDMLC implementation, additional MLC static patterns were also simulated and compared to additional measurements. Furthermore, the ability to simulate dynamic MLC fields was implemented in the HDMLC CM. The simulation results of these fields were compared with EBT2 film measurements performed in a solid water phantom. Results: Overall, the discrepancies, with and without MLC, between the opened field simulations and the measurements using ionization chambers in a water phantom, for the off-axis profiles are below 2% and in depth-dose profiles are below 2% after the maximum dose depth and below 4% in the build-up region. On the conditions of these simulations, this tungsten-based MLC has a density of 18.7 g cm− 3 and an overall leakage of about 1.1 ± 0.03%. The discrepancies between the film measured and simulated closed and blocked fields are below 2% and 8%, respectively. Other measurements were performed for alternated leaf patterns and the agreement is satisfactory (to within 4%). The dynamic mode for this MLC was implemented and the discrepancies between film measurements and simulations are within 4%. Conclusions: The Varian® Trilogy® (2300 C/D) linear accelerator including the HD120 MLC was successfully modeled and simulated using the Monte CarloBEAMNRC code by developing an independent CM, the HDMLC CM, either in static and dynamic modes.

Indicadores das condições nutricionais na região Polonoroeste: V. Desnutrição protéico-energética e parasitoses intestinais em um grupo de crianças de 3 a 72 meses de idade da cidade de Mirassol D'Oeste, Mato Grosso, Brasil

Este trabalho tem por objetivo caracterizar a desnutrição protéico-energética associada a parasitose intestinal em grupo de 149 crianças de ambos os sexos, na faixa etária de 3 a 72 meses, da cidade de Mirassol D'Oeste, na região do Projeto Polonoroeste em Mato Grosso. De cada criança foram coletados os seguintes dados: sexo, peso, idade e amostra de fezes para exame parasitológico. Os dados peso/idade obtidos foram analisados pelos critérios de GOMEZ. Utilizou-se como padrão de referência o National Center for Health Statistic (NCHS). Para diagnóstico dos parasitas intestinais executou-se o método de Hoffman, Pons e Janer. O grupo estudado constitui-se em sua maioria de crianças desnutridas, sendo a forma leve de desnutrição mais comum que as formas moderada e grave. As enteroparasitoses foram encontradas em 69% das amostras examinadas. A "Giardia lamblia" foi o protozoário mais comum e o "Ancilostomídeo" o helminto mais encontrado. O teste X² não mostrou relação de dependência entre o estado nutricional e a freqüência de enteroparasitoses.

Adaptive modeling and high quality spectral estimation for speech enhancement

In this work an adaptive modeling and spectral estimation scheme based on a dual Discrete Kalman Filtering (DKF) is proposed for speech enhancement. Both speech and noise signals are modeled by an autoregressive structure which provides an underlying time frame dependency and improves time-frequency resolution. The model parameters are arranged to obtain a combined state-space model and are also used to calculate instantaneous power spectral density estimates. The speech enhancement is performed by a dual discrete Kalman filter that simultaneously gives estimates for the models and the signals. This approach is particularly useful as a pre-processing module for parametric based speech recognition systems that rely on spectral time dependent models. The system performance has been evaluated by a set of human listeners and by spectral distances. In both cases the use of this pre-processing module has led to improved results.

Testagem do 1 - beta - D - Ribofuranosil, 1.2.4 - triazole - 3 - carboxamide em pacientes com hepatite

Realizou-se estudo do tipo duplo anonimato em 18 pacientes com hepatite aguda benigna. O gruoo experimental foi testado com uma provável droga de ação antiviral: 1-BETA-D-RIBOFURANOSIL, 1,2,4-TRIAZOLE-3- CARBOXAMIDE. O grupo controle ingeriu um placebo de lactose. Teve-se especial cuidado na seleção de pacientes, incluindo apenas pacientes que preenchessem critérios bem estabelecidos. Os pacientes foram seguidos semanalmente, avaliando-os clínica e laboratorialmente. Os resultados não evidenciaram diferenças significativas entre os dois grupos, sugerindo-se estudos com casuística mais numerosa e em regime de internação hospitalar.

Utilidade Clínica do (1->3) B-D-glucano como marcador laboratorial no diagnóstico de Pneumonia por Pneumocystis jirovecii

A pneumonia por Pneumocystis jirovecii (PPc) é uma das principais causas de morte em doentes imunocomprometidos, revestindo-se assim de elevado interesse o diagnóstico precoce desta infecção, por forma a instaurar a terapêutica adequada. Actualmente, os meios laboratoriais de diagnóstico baseiam-se fundamentalmente na detecção directa deste microrganismo nas secreções pulmonares dos doentes, o que implica a realização de procedimentos invasivos. É nessa perspectiva que surge o doseamento do β-glucano no soro de doentes com presumível infecção, uma vez que, este composto é um dos principais componentes da parede dos quistos de P. jirovecii. Neste estudo procedeu-se ao doseamento do β-glucano em amostras de soro de 66 indivíduos e verificou-se que, nos 47 indivíduos que confirmaram o diagnóstico de PPc, a mediana de β-glucano obtida foi de 314,5 pg/mL, enquanto nos restantes 19 foi de 63,7 pg/mL. Estatisticamente obteve-se uma forte correlação entre níveis elevados de β-glucano no soro de doentes e a presença de infecção por P. jirovecii. Em relação ao diagnóstico clínico, os resultados obtidos demonstraram correlação entre um diagnóstico clinico sugestivo de PPc e níveis elevados de β-glucano no soro. Constatou-se ainda que, para a infecção por P. jirovecii o cut-off que apresentou melhores resultados para o teste Fungitell® situa-se nos 100 pg/mL, obtiveram-se resultados de sensibilidade de 89% e especificidade de 74%. Estudos preliminares apontaram para o facto de níveis elevados de β-glucano no soro corresponderem a níveis elevados de parasitémia e uma evolução clínica negativa da doença.

Influence de deux milieux séquentiels pour la culture d'embryons sur la production d'hormone gonadotrophine chorionique et de progestérone par des cellules JEG-3 et BeWo [Effects of different embryo development media on hCG and progesterone release by JEG-3 and BeWo cells]

Current in vitro fertilisation (IVF) practice requires synchronisation between the¦environment of cultured oocytes and embryos and the surroundings to what they would have¦been exposed to in vivo. Commercial, sequential media follow this requirement but their exact¦composition is not available. We have compared two widely used IVF culture media systems using¦the two choriocarcinoma cell lines JEG-3 and BeWo. The two hormones hCG and progesterone¦were determined in the culture supernatants as endpoints. In both cell lines, but in a more¦pronounced way in JEG-3, progesterone rather than hCG production was stimulated, and a¦higher hormone release was observed in the fertilisation than in the cleavage media. Differences¦between manufacturers were small and did not favour one system over the other. We conclude¦that both sequential media systems can be equally well used in current IVF laboratory practice.¦© 2012 Elsevier Masson SAS. All rights reserved.

3-Regime symmetric STAR modeling and exchange rate reversion

The breakdown of the Bretton Woods system and the adoption of generalized oating exchange rates ushered in a new era of exchange rate volatility and uncer- tainty. This increased volatility lead economists to search for economic models able to describe observed exchange rate behavior. In the present paper we propose more general STAR transition functions which encompass both threshold nonlinearity and asymmetric e¤ects. Our framework allows for a gradual adjustment from one regime to another, and considers threshold e¤ects by encompassing other existing models, such as TAR models. We apply our methodology to three di¤erent exchange rate data-sets, one for developing countries, and o¢ cial nominal exchange rates, the sec- ond emerging market economies using black market exchange rates and the third for OECD economies.
