Cansinos y 'El arrabal de la literatura' : Un texto germinal del barrio borgeano

La singular preocupación de Jorge Luis Borges por la identidad argentina en las primeras décadas del 1900 puede ser retomada desde dos puntos de partida. Uno, esencialmente lingüístico, relacionado con la problemática idiomática de su país natal: el idioma de los argentinos. El otro, de índole socio-cultural, vinculado al espacio y a la vida de los personajes que, en algunas décadas anteriores, habitaron el Buenos Aires periférico: el arrabal y sus compadres. Y es en ambos puntos que el presente trabajo debate sobre la influencia de Rafael Cansinos Assens, su admirado y estimado maestro, en los textos juveniles del argentino. Influencia que es perceptible tanto en los estudios borgeanos sobre las posibilidades y trampas del lenguaje, posiblemente alentados en las discusiones de las tertulias del sevillano (y en el ultraísmo fugaz de ambos escritores), como, especialmente, en las consideraciones de Cansinos Assens sobre el suburbio en su particular texto 'El arrabal de la literatura'

Composition of basalts from the Romanche Fracture Zone

New magnetometric, petrological, and geochemical data on basalts from the central Romanche Fracture Zone allow to classify these rocks into two groups. Igneous rocks from the active part of the fracture zone that have undergone transtension are referred to alkaline rocks. According to some indications, they are younger that oceanic tholeiites of the southern fault-line ridge, which were affected by elevated pressure in the past. These data indicate with a high probability that the Romanche Fracture Zone belongs to a rare group of magmatically active demarcation transform lines that separate large oceanic domains different in structural and geochemical features.

Some hydrophysical and hydrochemical parameters of the upper part of the hydrogen sulfide zone in the Black Sea, September 11-22, 1994

Features of spatial variability of hydrogen sulfide in the northeastern part of the Black Sea are estimated. Some technical aspects of H2S concentration determination in the anoxic zone are discussed: in its upper part at H2S concentration <30 µmol/l, the photometric method is recommended, while for deeper layers the iodometric method should be used. With linearity of vertical distribution of hydrogen sulfide and ammonium taken into account their vertical gradients are estimated as 0.49+/-0.04 µmol/m and 0.19+/-0.06 µmol/m respectively. It is shown that the upper boundary of the H2S layer corresponds to the isopycnal surface with Sigma_t = 16.19+/-0.05 arbitrary units. Special attention is paid to relationship of hydrogen sulfide distribution with hydrophysical features in the region under study, in particular in the coastal zone. It is shown that hydrodynamic conditions control spatial distribution of hydrogen sulfide. On the basis of isopycnal treatment of the H2S field existence of a coastal convergence zone is proved, and peculiarities are recognized of vertical circulation in the main Black Sea gyre and coastal anticyclonic eddies; here hydrogen sulfide serves as a tracer of hydrophysical mixing processes.
