La grande guerra apocalisse della modernità: Ungaretti e gadda

This essay sketches a route in the history of the modern idea of “apocalyptic”in relation to the event of the Great War, focusing on the apocalyptic epiphanies in poetical texts of two of the greatest Italian writers who fought inthe First World War: Carlo Emilio Gadda and Giuseppe Ungaretti. The poemsof Porto Sepolto (1916), written and published during the War, and the storiesof Carlo Emilio Gadda, which retain traces of that War, even after several years, remain exemplary testimony to the various features of the apocalypticperception of the World War I, that was the terrible and striking explosion ofModernity

Radio Echo Sounding (RES) investigations at Talos Dome (East Antarctica): bedrock topography and ice thickness

Radio echo sounding measurements were collected during two Antarctic expeditions to determine the ice thickness and the sub-glacial morphology of Talos Dome in the region around 72°48'S; 159°06'E (about 6400 km2) on the edge of the East Antarctic plateau adjacent to Victoria Land in the western Ross Sea sector. The increasing interest in this region is due to the fact that in this area the ice accumulation is higher than in other sites in East Antarctica. Because of this, Talos Dome could be a new site for a project of a deep ice core drilling to obtain information on climate changes near the coast of Antarctica. In this frame, the knowledge of the bedrock topography is of great importance to choose the best location for the drilling site. In this paper, airborne radio echo sounding results from two Antarctic expeditions (1997 and 1999) are presented. Bedrock topography in bi- and three-dimensions for the Talos Dome region are discussed

Pd2Si surfaces thermally enriched in silicon: Evidence of new Si:Pd bonds

Thermally induced Si accumulation onto Pd2Si surfaces has been studied for the first time with synchrotron radiation photoemission. Evidence is given of the formation of strong bonds between Si and Pd in the transition region between Pd2Si and Si. The results are discussed in view of the Pd-Si interfaces prepared by annealing in device technology

Elaboración de un sucedáneo de queso– Tofu- con el agregado de gírgolas (Pleurotus Ostreatus)

Actualmente el mercado demanda productos alimenticios de procedencia natural con beneficios para la salud del consumidor. Asimismo, crecen las preparaciones gastronómicas con reemplazo de proteína animal por vegetal. El objetivo de este trabajo fue obtener un sucedáneo de queso de alto valor nutricional derivado del grano de soja con gírgolas y evaluar su aceptabilidad por parte del consumidorEstación Experimental Agropecuaria BarilocheFil: Mellado, Julio Cesar.

A functional calcium-transporting ATPase encoded by chlorella viruses

Calcium-transporting ATPases (Ca2+ pumps) are major players in maintaining calcium homeostasis in the cell and have been detected in all cellular organisms. Here, we report the identification of two putative Ca2+ pumps, M535L and C785L, encoded by chlorella viruses MT325 and AR158, respectively, and the functional characterization of M535L. Phylogenetic and sequence analyses place the viral proteins in group IIB of P-type ATPases even though they lack a typical feature of this class, a calmodulin-binding domain. A Ca2+ pump gene is present in 45 of 47 viruses tested and is transcribed during virus infection. Complementation analysis of the triple yeast mutant K616 confirmed that M535L transports calcium ions and, unusually for group IIB pumps, also manganese ions. In vitro assays show basal ATPase activity. This activity is inhibited by vanadate, but, unlike that of other Ca2+ pumps, is not significantly stimulated by either calcium or manganese. The enzyme forms a 32P-phosphorylated intermediate, which is inhibited by vanadate and not stimulated by the transported substrate Ca2+, thus confirming the peculiar properties of this viral pump. To our knowledge this is the first report of a functional P-type Ca2+-transporting ATPase encoded by a virus
