Las Crónicas del Ángel Gris, primera obra literaria de Alejandro Dolina, presenta entre otras particularidades un interesante problema de crítica textual, ya que su proceso de producción está compuesto por tres etapas y sólo culmina tras dieciséis años de minuciosa reelaboración. Este artículo analiza los testimonios textuales de dicho proceso y los interpreta como un tributo a la memoria re-creadora y como una notoria muestra de la maduración artística del escritor.

En el libro, se hace una revisión del significado de la arquitectura de Miguel Ángel, pasando de la interpretación neoplatónica, bastante generalizada, a una visión en la que los elementos que componen dicho conjunto se revelan en una clave naturalista y vital más próxima a los planteamientos antropológicos de Aristóteles. La autora, hace un pormenorizado estudio del Campidoglio, deteniéndose, en primer lugar, en las circunstancias políticas y culturales que dieron origen al proyecto y analizando el programa urbanístico y funcional. A continuación, se brinda al lector una descripción fenomenológica del Campidoglio basada en la experiencia directa de la obra de Miguel Ángel y corrobora dicha experiencia con los testimonios de la época así como los datos aportados por los estudiosos de la obra del artista.

An integrated instrument package for measuring and understanding the surface radiation budget of sea ice is presented, along with results from its first deployment. The setup simultaneously measures broadband fluxes of upwelling and downwelling terrestrial and solar radiation (four components separately), spectral fluxes of incident and reflected solar radiation, and supporting data such as air temperature and humidity, surface temperature, and location (GPS), in addition to photographing the sky and observed surface during each measurement. The instruments are mounted on a small sled, allowing measurements of the radiation budget to be made at many locations in the study area to see the effect of small-scale surface processes on the large-scale radiation budget. Such observations have many applications, from calibration and validation of remote sensing products to improving our understanding of surface processes that affect atmosphere-snow-ice interactions and drive feedbacks, ultimately leading to the potential to improve climate modelling of ice-covered regions of the ocean. The photographs, spectral data, and other observations allow for improved analysis of the broadband data. An example of this is shown by using the observations made during a partly cloudy day, which show erratic variations due to passing clouds, and creating a careful estimate of what the radiation budget along the observed line would have been under uniform sky conditions, clear or overcast. Other data from the setup's first deployment, in June 2011 on fast ice near Point Barrow, Alaska, are also shown; these illustrate the rapid changes of the radiation budget during a cold period that led to refreezing and new snow well into the melt season.
