Recurrent noise-induced phase singularities in drifting patterns
(2015)
We show that the key ingredients for creating recurrent traveling spatial phase defects in drifting patterns are a noise-sustained structure regime together with the vicinity of a phase transition, that is, a spatial region ...
Disturbance zonal and vertical plasma drifts in the Peruvian sector during solar minimum phases
(American Geophysical Union, 2016-02-11)
In the present work, we investigate the behavior of the equatorial F region zonal plasma drifts over the Peruvian region under magnetically disturbed conditions during two solar minimum epochs, one of them being the recent ...
Low-latitude ionospheric disturbance electric field effects during the recovery phase of the 19-21 October 1998 magnetic storm
(American Geophysical Union, 2003-12-23)
Low‐latitude ionospheric electric fields and currents are often strongly disturbed during periods of enhanced geomagnetic activity. These perturbations can last for several hours after geomagnetic quieting. We use incoherent ...
Evolução estratigráfica da sucessão drifte regressiva da Bacia Potiguar (NE do Brasil)
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM GEODINÂMICA E GEOFÍSICA, 2018-08-30)
The Potiguar Basin is located at the intersection between the east and equatorial Brazilian
margins, covering areas of the Rio Grande do Norte and Ceará states. The sedimentary filling
of this basin is represented by ...
DRIFT+MS Quantitative Study of the CO Oxidation on Gold supported on Ceria
(VI San Luis School and Conference on Surfaces, Interfaces and Catalysis, 2019)
The steps of the CO oxidation reaction on a Au/CeO2 catalyst was quantitatively investigated using a novel DRIFT cell/micro-reactor. The design and characterization of this DRIFT cell/micro-reactor, coupled with mass ...
Digisonde spread F and GPS phase fluctuations in the equatorial ionosphere during solar maximum
(American Geophysical Union, 2006-12-06)
The Jicamarca (11.95°S, 76.87°W) digisonde and the Arequipa (16.47°S, 71.49°W) GPS receiver observed the equatorial F region irregularities on the western South America from April 1999 to March 2000. The spread F measured ...
Comparison of ionosonde and incoherent scatter drift measurements at the magnetic equator
(American Geophysical Union, 2006-01-10)
It has been proposed that ionosondes can be used to measure vectorial nighttime ionospheric drifts at F region altitudes. These measurements have been validated at mid and high magnetic latitudes on campaign basis. Here ...
Crotonaldehyde Hydrogenation on Rh/TiO2 catalysts: In situ DRIFTS studies
(Sociedad Chilena de Química, 2002)
Storm time equatorial plasma bubble zonal drift reversal due to disturbance Hall electric field over the Brazilian region
(American Geophysical Union, 2016-05-18)
The dynamics of equatorial ionospheric plasma bubbles over Brazilian sector during two magnetic storm events are investigated in this work. The observations were made at varying phases of magnetic disturbances when the ...
