La medicina anatomoclínica y su llegada y consolidación en Chile: 1833-1843

El presente trabajo trata de dar cuenta de explicar el proceso por el cual la medicina anatomoclínica configurada en Francia durante el siglo XVIII llega y se consolida en Chile durante 1833 a 1843. Par el desarrollo de este objetivo el trabajo consta de dos partes principales. En la primera parte se hace un estudio a profundidad sobre la configuración de la medicina anatomoclínica en Francia durante la Revolución Francesa. Esto nos permite entender que la constitución de esta medicina se da de la mano con la construcción del Estado Nacional francés y, así mismo, que este proceso se caracteriza por un cambio en la mentalidad de lo que significa la enfermedad y la manera en la que el oficio médico es entendido. La segunda parte es un estudio sobre cómo esta medicina llega a Chile y se consolida durante un periodo político particular en el que a la vez se institucionaliza la educación médica, se constituye un Estado Nación Chileno y se evidencia un cambio de los fundamentos de la medicina.

Decadal predictability of regional-scale peak winds over Europe using the Earth System Model of the Max-Planck-Institute for Meteorology

The predictability of high impact weather events on multiple time scales is a crucial issue both in scientific and socio-economic terms. In this study, a statistical-dynamical downscaling (SDD) approach is applied to an ensemble of decadal hindcasts obtained with the Max-Planck-Institute Earth System Model (MPI-ESM) to estimate the decadal predictability of peak wind speeds (as a proxy for gusts) over Europe. Yearly initialized decadal ensemble simulations with ten members are investigated for the period 1979–2005. The SDD approach is trained with COSMO-CLM regional climate model simulations and ERA-Interim reanalysis data and applied to the MPI-ESM hindcasts. The simulations for the period 1990–1993, which was characterized by several windstorm clusters, are analyzed in detail. The anomalies of the 95 % peak wind quantile of the MPI-ESM hindcasts are in line with the positive anomalies in reanalysis data for this period. To evaluate both the skill of the decadal predictability system and the added value of the downscaling approach, quantile verification skill scores are calculated for both the MPI-ESM large-scale wind speeds and the SDD simulated regional peak winds. Skill scores are predominantly positive for the decadal predictability system, with the highest values for short lead times and for (peak) wind speeds equal or above the 75 % quantile. This provides evidence that the analyzed hindcasts and the downscaling technique are suitable for estimating wind and peak wind speeds over Central Europe on decadal time scales. The skill scores for SDD simulated peak winds are slightly lower than those for large-scale wind speeds. This behavior can be largely attributed to the fact that peak winds are a proxy for gusts, and thus have a higher variability than wind speeds. The introduced cost-efficient downscaling technique has the advantage of estimating not only wind speeds but also estimates peak winds (a proxy for gusts) and can be easily applied to large ensemble datasets like operational decadal prediction systems.

Resistência de genótipos de feijoeiro a Zabrotes subfasciatus (Bohemann, 1833) (Coleoptera: Bruchidae)

Durante o armazenamento de grãos de feijão (Phaseolus vulgaris L.), o rendimento pode ser reduzido devido às infestações de carunchos como os da espécie Zabrotes subfasciatus (Bohemann, 1833) (Coleoptera: Bruchidae). O ataque desse inseto afeta diretamente a qualidade dos grãos, além de facilitar a entrada de patógenos, tornando-os inviáveis para o consumo e/o comércio. Com a finalidade de buscar uma estratégia alternativa para o controle deste caruncho, avaliou-se a possível resistência de linhagens quase isogênicas contendo arcelina, linhagens selvagens contendo arcelina e cultivares comerciais de feijoeiro, em laboratório (T= 25±2° C, U.R.= 70±10% e fotoperíodo= 12h). Foram utilizados frascos contendo 10 g de grãos dos genótipos, os quais foram infestados por uma semana com sete casais do caruncho. Vinte e um dias após a infestação, os grãos foram avaliados contando-se o número de ovos viáveis. A partir de 25 dias da infestação, os grãos foram observados diariamente avaliando-se o número e o peso dos insetos emergidos, a viabilidade larval, o ciclo biológico (ovo-adulto) e o peso de grãos consumidos. Empregou-se um delineamento inteiramente casualizado, com oito repetições. Os genótipos Arc.2, Arc.3, Arc.4, Arc.3S e Ipa 6 expressaram baixos níveis de não-preferência para oviposição e foram classificados como deterrentes. Os genótipos Arc.1S e Arc.1 expressaram elevados níveis de antibiose; Arc.2, Arc.3 e Arc.4 apresentam o mesmo mecanismo, porém, em níveis inferiores.

A g-factor metric for k-t-GRAPPA- and PEAK-GRAPPA-based parallel imaging.

PURPOSE The aim of this work is to derive a theoretical framework for quantitative noise and temporal fidelity analysis of time-resolved k-space-based parallel imaging methods. THEORY An analytical formalism of noise distribution is derived extending the existing g-factor formulation for nontime-resolved generalized autocalibrating partially parallel acquisition (GRAPPA) to time-resolved k-space-based methods. The noise analysis considers temporal noise correlations and is further accompanied by a temporal filtering analysis. METHODS All methods are derived and presented for k-t-GRAPPA and PEAK-GRAPPA. A sliding window reconstruction and nontime-resolved GRAPPA are taken as a reference. Statistical validation is based on series of pseudoreplica images. The analysis is demonstrated on a short-axis cardiac CINE dataset. RESULTS The superior signal-to-noise performance of time-resolved over nontime-resolved parallel imaging methods at the expense of temporal frequency filtering is analytically confirmed. Further, different temporal frequency filter characteristics of k-t-GRAPPA, PEAK-GRAPPA, and sliding window are revealed. CONCLUSION The proposed analysis of noise behavior and temporal fidelity establishes a theoretical basis for a quantitative evaluation of time-resolved reconstruction methods. Therefore, the presented theory allows for comparison between time-resolved parallel imaging methods and also nontime-resolved methods. Magn Reson Med, 2014. © 2014 Wiley Periodicals, Inc.
