Filón de Alejandría : Obra y pensamiento. Una lectura filológica

Filón de Alejandría (30?a. C.-50? d. C.) es una figura clave para conocer la profunda relación entre Judaísmo y Helenismo en el siglo I d. C. Judío practicante, su profundo dominio de la lengua, la literatura y, de modo especial, la retórica griegas lo convierten en una personalidad extraordinaria de su tiempo, tanto por su exégesis de la Torá (o Pentateuco) como por sus escritos apologéticos, históricos y filosóficos. Su testimonio es de gran valor para todo estudioso de la Antigüedad clásica por los muchos datos que aporta acerca de la filosofía, el pensamiento, la educación y la tradición clásica en el momento histórico que le tocó vivir, precisamente en un centro cultural de excepcional importancia dentro del Imperio romano

Geochemistry and isotopic ratios of basalts obtained during R/V Akademik Nikolaj Strakhov cruise ANS25

Based on the investigation of samples recovered during Cruise 25 of the R/V ''Akademik Nikolai Strakhov'', the character of magmatism was determined in the flank parts of the rift zone at the 74°05'N and 73°50'N region, where the direction of the rift valley changes from the north-northwest in the Knipovich Ridge to the northeast-trending structures of the Mohns Ridge. It was shown that the tholeiitic magmas of this region shows all the geochemical characteristics of TOR-2, which is typical of the Mohns Ridge and most oceanic rift zones worldwide, and differ from the basalts of the Knipovich Ridge, which are assigned to a shallower type of tholeiitic magmatism (Na-TOR). The persistent depletion of the magmas in terms of lithophile element contents and radiogenic isotope ratios of Sr, Nd, and Pb reflects the conditions of their formation during the ascent of the depleted oceanic mantle, which has occurred without significant complications since the early stages of the formation of the Mohns Ridge.
