Sobre la utilidad, seguridad y suavidad de la inoculación (1779). Discurso de Timoteo O'Scanlan (1726-1795) en la Real Academia de Medicina

Reconocido como una de las figuras clave en la difusión de la inoculación contra la viruela en España, el médico de origen irlandés Timoteo O'Scanlan dejó publicadas 3 obras y numerosos artículos de prensa en los que plasmó su pericia e interés por una práctica que se inició de forma tardía en nuestro país. Aceptado como miembro de la Real Academia Médica de Madrid en noviembre de 1778, leyó su discurso de ingreso en abril de 1779. El texto, que constituye la primera aproximación de O'Scanlan a la inoculación, que venía practicando con éxito desde 1771, fue incluido con algunas modificaciones y sin citar la fecha de redacción en la introducción de su primera obra, Práctica moderna de la inoculación (1784). El manuscrito se encuentra en el Archivo del Conde de Campomanes (Fundación Universitaria Española, Madrid).

A compact difference scheme for numerical solutions of second order dual-phase-lagging models of microscale heat transfer

Dual-phase-lagging (DPL) models constitute a family of non-Fourier models of heat conduction that allow for the presence of time lags in the heat flux and the temperature gradient. These lags may need to be considered when modeling microscale heat transfer, and thus DPL models have found application in the last years in a wide range of theoretical and technical heat transfer problems. Consequently, analytical solutions and methods for computing numerical approximations have been proposed for particular DPL models in different settings. In this work, a compact difference scheme for second order DPL models is developed, providing higher order precision than a previously proposed method. The scheme is shown to be unconditionally stable and convergent, and its accuracy is illustrated with numerical examples.

Construction of 17-19th century domes in the province of Alicante (Spain): the case of San Juan Bautista in Cox

From the late seventeenth to early nineteenth centuries, many religious temples have been built in the province of Alicante (south east of Spain) with brick domes as their main characteristic feature. Often, the limited data available about these remarkable constructions make rehabilitation interventions become into real research projects, with a high value for their historic conservation over time. The aim of this paper is to show a detailed refurbishment analysis of a religious temple built in 1778, showing the need of preservation of historic buildings as a part of the architectural heritage by establishing a common pattern of materials, geometry and constructive systems, specifically in their domes. In most cases, there was not an architectural project for the construction, that is why the analysis of any documentary and archival sources available is essential to find different ways to proceed on the use and maintenance of these religious buildings.
