Description and chemical composition of manganese deposits during the deep-sea expedition of the streamer Valdivia in 1898-1899

This monograph forms the fourth part of the tenth volume of the scientific results of the voyage of the German exploring ship Valdivia in the Atlantic and Indian Oceans, made during the years 1898-1899. These volumes are published under the editorship of Prof. Chun, the zoologist of Leipzig, who was leader of the expedition ; and Prof. E. Philippi with the cooperation of Sir John Murray. The nature of the materials brought up at various points during the voyage is well illustrated by a series of plates, similar to those accompanying the Challenger volumes. Among the concretions from the Agulhas Bank were found phosphatic nodules containing 33 per cent, of calcium carbonate, 28 of calcium phosphate, 14.6 of calcium sulphate, and 4.8 of magnesium carbonate, with some ferric oxide, alumina, and silica. These nodules were dredged at a depth of 155 metres. Off the coast of Namibia, a large quantity of manganese nodules were also dredged. Their chemical analysis performed at the Mineralogical Institute of the University Jena show similar composition as the nodules recovered by the "Challenger" at station 253 in the Pacific Ocean.

La resignificación del muralismo mexicano en Mendoza : (1952-1961)

El movimiento plástico desarrollado en Mendoza en la década del '50 congregó a un grupo de jóvenes artistas con un ideal común: acercar el arte a la mayoría, partiendo de la consideración de la producción artística como trabajo colectivo. Constituyeron el Club de Grabados y Taller de Murales, emprendimientos originados en el pequeño taller del maestro Luis Quesada, quien congregaba a estudiantes de arte e intelectuales para experimentar la técnica del grabado y debatir sobre temas que colocaban a la actividad artística en relación con la realidad social, política, económica de época. Lo llamaron Taller de Arte Popular Realista y fue la matriz ideológica y experimental de la que surgirán luego una serie de proyectos tendientes a difundir la práctica de un arte comprometido socialmente.
