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.

Comparison of polar ozone loss rates simulated by one-dimensional and three-dimensional models with Match observations in recent Antarctic and Arctic winters

Simulations of ozone loss rates using a three-dimensional chemical transport model and a box model during recent Antarctic and Arctic winters are compared with experimental loss rates. The study focused on the Antarctic winter 2003, during which the first Antarctic Match campaign was organized, and on Arctic winters 1999/2000, 2002/2003. The maximum ozone loss rates retrieved by the Match technique for the winters and levels studied reached 6 ppbv/sunlit hour and both types of simulations could generally reproduce the observations at 2-sigma error bar level. In some cases, for example, for the Arctic winter 2002/2003 at 475 K level, an excellent agreement within 1-sigma standard deviation level was obtained. An overestimation was also found with the box model simulation at some isentropic levels for the Antarctic winter and the Arctic winter 1999/2000, indicating an overestimation of chlorine activation in the model. Loss rates in the Antarctic show signs of saturation in September, which have to be considered in the comparison. Sensitivity tests were performed with the box model in order to assess the impact of kinetic parameters of the ClO-Cl2O2 catalytic cycle and total bromine content on the ozone loss rate. These tests resulted in a maximum change in ozone loss rates of 1.2 ppbv/sunlit hour, generally in high solar zenith angle conditions. In some cases, a better agreement was achieved with fastest photolysis of Cl2O2 and additional source of total inorganic bromine but at the expense of overestimation of smaller ozone loss rates derived later in the winter.

Teixeira de Freitas leitor de Savigny

The international circulation and reception of the works of Friedrich Carl von Savigny (1779-1861) constitute one of the main features of the first globalization of legal thought. Reaching law professors and practitioners from Brazil to Japan, readings of Savigny’s books offer a promising perspective for understanding how legal cultures around the world coped with the challenges of modernity. By focusing empirically on the circulation of books and analytically on the adaptation of texts to local contexts, the approach forwarded here tries to capture the creative aspects of the diffusion of knowledge. For this purpose, it concentrates on Brazilian readers of Savigny in the 19th Century, especially on the celebrated lawyer Augusto Teixeira de Freitas (1816-1883). It argues that Savigny’s works provided a decisive argumentative framework for some of the main issues discussed in Brazilian jurisprudence of the time. Freitas’ work documents a productive reading of Savigny that shaped his views on both normative and methodological issues, from slavery to codification. By tracing Freitas’ selective appropriation of Savigny’s texts, the article concludes that he was able both to reproduce and to subvert Savigny’s conception of private law, whenever the local context and his personal convictions demanded him to.
