"El muerto" de Borges como laberinto de una sola línea

La hipótesis del trabajo es que "El muerto" es una variante más criolla y menos compleja de "La muerte y la brújula". El laberinto se reduce a una sola línea, como Lönrott pedía. Se narra una suerte de caricatura donde el lector eficaz no compite con un par sino con alguien que descifra los signos con torpeza. Un cruce textual, con la línea del laberinto griego como fondo, en ese camino que llevó a Borges de los duelos de cuchillo de los veinte a los duelos de lectura alrededor de un argumento de los años cuarenta

Chemical composition, age, and magnetic parameters of igneous rocks from the Franz Josef Land

A combined study of magnetic parameters of basalt and andesite samples has been carried out in the framework of geological investigations of the Franz Josef Land. This study has included determination of coercivity, saturation magnetization, Curie points, natural remanent magnetization (NRM), and magnetic susceptibility as well as examination of ferromagnetic minerals with a microscope. Data on chemical composition of the rocks have been obtained for all the samples, and radiological ages have been determined for the majority of the rocks. Thermomagnetic curves of the samples have been subdivided into four types depending on composition of ferromagnetic NRM carriers. Data showing multiple changes in the predominant composition of the igneous rocks have been obtained. Each stage of magmatism is characterized by a specific type of the ferromagnetic component in the rocks and, therefore, magnetomineralogical investigations can be used for differentiation and correlation of the igneous rocks.
