F-Region electron density irregularities during the development of equatorial plasma bubbles [PDF]
Geofísica Internacional, 2000 The height variation of the ionospheric electron density was measured with rocket-borne electron density probes in two campaigns conducted from Alcantara (2.31°S; 35.2°W), Brazil. A Black Brant X sounding rocket was launched on 14 October 1994 at 1955hrs

EXPERIMENTAL DETERMINATION OF TEMPERATURES IN SPARK GENERATED BUBBLES OSCILLATING IN WATER
Acta Polytechnica, 2017 The surface temperatures of the plasma core in the final stages of the first contraction phase of spark-generated bubbles oscillating under ordinary laboratory conditions in a large expanse of water are determined experimentally.

Ionospheric S4 Scintillations from GNSS Radio Occultation (RO) at Slant Path
Remote Sensing, 2020 Ionospheric scintillation can significantly degrade the performance and the usability of space-based communication and navigation signals. Characterization and prediction of ionospheric scintillation can be made from the Global Navigation Satellite ...

Global modeling of equatorial plasma bubbles [PDF]
Geophysical Research Letters, 2010 The NRL three‐dimensional ionospheric simulation code SAMI3 is used to model the onset and evolution of equatorial spread F (ESF). SAMI3 is a comprehensive ionosphere model that has been modified to self‐consistently solve for the global neutral wind driven dynamo electric field as well as the gravity driven electric field associated with plasma ...

Hydrogen peroxide generation by DC and pulsed underwater discharge in air bubbles [PDF]
, 2012 The generation of H(2)O(2) in underwater discharge in air bubbles is studied with consideration of the influence of electrodes polarity, input power, solution conductivity and the inter-electrode distance.

Solar prominences: 'double, double ... boil and bubble'
, 2015 Observations revealed rich dynamics within prominences, the cool 10,000 K, macroscopic (sizes of order 100 Mm) "clouds" in the million degree solar corona. Even quiescent prominences are continuously perturbed by hot, rising bubbles.

Plasma and cavitation dynamics during pulsed laser microsurgery in vivo
, 2007 We compare the plasma and cavitation dynamics underlying pulsed laser microsurgery in water and in fruit fly embryos (in vivo) - specifically for nanosecond pulses at 355 and 532 nm. We find two key differences. First, the plasma-formation thresholds are
