The impact of soil moisture–atmosphere coupling on daily maximum surface temperatures in Southeastern South America

T. Coronato, A. Carril, P. Zaninelli, J. Giles, R. Ruscica, M. Falco, A. Sörensson, L. Fita, L. Li, and C. …

Based on a series of experiments conducted by two regional climate models (RCA4 and LMDZ) with and without soil moisture-atmosphere coupling, we investigate the role of soil moisture on the occurrence of surface air temperature extremes and its persistence in …

Study of the red blood cell aggregation by coherent anti-Stokes Raman spectroscopy

M. Toderi, G. Galizzi, B. Riquelme, and D. Dumas

In this work, we studied the nature of the molecular bonds involved in the red blood cell aggregation process by the coherent anti-Stokes Raman spectroscopy technique. Images were acquired with a commercial Leica TCS SP8 CARS confocal microscope (Leica Microsystems …

Growing Fe-Mn-Al-Ni single crystals by combining directional annealing and thermal cycling

J. Vallejos and J. Malarría

In pseudoelastic alloys, a fine-grained microstructure implies restrictions on the propagation and shrinkage of the martensitic phase. Thus, the pseudoelastic effect is adversely affected. For this reason, thermomechanical methods that accelerate grain growth are sought in these alloys. In this …

Delay control in laser-assisted photoionization of water molecules by attopulses

L. Martini, D. Boll, and O. Fojón

The knowledge of the ionization of water is essential in different fields such as Biology and Atomic Physics. Basic reactions involving this molecule are crucial to understand the interaction between radiation and the biological tissue because living cells are composed …

A sparse spectrum technique for gridding and separating potential field anomalies

F. Guspi and B. Introcaso

The discrete Fourier transform of a potential field, measured at stations irregularly distributed on a surface, is modeled by means of a high-resolution sparse estimate derived originally for seismic signal processing. The coefficients of this estimate produce a model with …

Alterations of the erythrocyte membrane by in vitro action of Trichinella spiralis muscle larvae

P. P. D. León, M. Bellini, H. Castellini, and B. Riquelme

The complex life cycle of Trichinella spiralis includes the migration of newborn larvae through the bloodstream to their encystment in muscle. The parasite establishes an intimate contact with the erythrocytes of the host both during the migration of the newborn …

Microstructure, texture and interface integrity in sheets processed by Asymmetric Accumulative Roll-Bonding

R. de Godoi, D. C. Magalhães, M. Avalos, R. Bolmaro, V. Sordi, and A. Kliauga

Accumulative Roll-Bonding (ARB) and Asymmetric Rolling (AR) techniques were combined to produce ultrafine-grained aluminum sheets with the mechanical characteristics of a Severe Plastic Deformation (SPD) process. Temperature and number of bonding cycles were varied to promote grain refinement, texture randomization …

Off-resonance-enhanced polarization control in two-color atomic ionization

D. Boll, L. Martini, O. Fojón, and A. Palacios

We investigate a polarization control scheme in two-color two-photon atomic ionization. Experiments employing free-electron laser or high-order harmonic generation sources have shown light polarization dependencies in above threshold ionization of atoms assisted with an IR field. These were mostly performed …

Effects of laser shock processing and shot peening on 253 MA austenitic stainless steel and their consequences on fatigue properties

L. Spadaro, S. Hereñú, R. Strubbia, G. G. Rosas, R. Bolmaro, and C. R. González

A comparative study of the influence of laser shock peening without coating (LSPwC) and shot peening (SP) treatments on the low cycle fatigue life of 253 MA austenitic stainless steel was investigated. LSPwC treatments were performed with 2500 pulse/cm2 and …
