La Espectroscopia de Plasmas Inducidos por Láser (LIBS) es una técnica espectroscópica que se basa en la generación de plasmas por ablación láser. En esta tesis se desarrolló e implementó la técnica LIBS para la...

The plasmasphere contains rich small-scale structure that plays a key role in regulating wave propagation and mass transport in the inner magnetosphere, yet the evolution of plasmaspheric density ducts remains poorly und...

In situ observations by Parker Solar Probe (PSP) suggest that the heliospheric current sheet (HCS) undergoes near-continuous magnetic reconnection close to the Sun, in stark contrast to scarce observations of this phenom...

Se presenta una herramienta para el procesamiento intensivo de imágenes digitales basada en unidades gráficas de procesamiento (GPU) y CPU de múltiple núcleo. La herramienta incorpora novedosos filtros para la elimin...

There is unequivocal evidence that alpha-synuclein plays a pivotal pathophysiological role in neurodegenerative diseases, and in particular in synucleinopathies. These disorders present with a variable extent of cognitiv...

Calibrated measurements of electron velocity distribution functions (VDFs) are necessary to characterize fluid and kinetic processes in weakly collisional and nearly collisionless plasmas such as the solar wind. Therefor...

We report the emergency development and application of a robust serologic test to evaluate acute and convalescent antibody responses to SARS-CoV-2 in Argentina. The assays, COVIDAR IgG and IgM, which were produced and pr...

Stark widths and shifts of Nb II spectral lines have been measured by laser-induced breakdown spectroscopy (LIBS). The experimental line profiles are obtained from spectra of the emission of laser-induced plasmas generat...

El interés por el desarrollo de algoritmos para el procesamiento de imágenes médicas orientadas al estudio del funcionamiento del sistema cardiovascular ha crecido ampliamente en los últimos años. En especial, el ul...

Abstract Background The bacterium Rhodococcus equi can cause severe pneumonia in foals. The absence of a licensed vaccine and limited effectiveness of commercial R. equi hyperimmune plasma (RE‐HIP) create a great need ...

In this paper, line profile analysis of several Cr transitions was carried out for characterization of a laser-induced plasma. The plasma was generated on a metallic alloy (nominal Cr concentration 29.7%) in air at atmos...
