Stability analysis of conducting jets under ac radial electric fields for arbitrary viscosity
(AIP Publishing, 2003-02)
A temporal linear modal stability analysis is presented for conducting viscous liquid jets flowing with nonzero velocity relative to an ambient gas and subjected to an ac radial electric field. Parametric resonance between ...

Influence of releases of 129I and 137Cs from European reprocessing facilities in Fucus vesiculosus and seawater from the Kattegat and Skagerrak areas
(ScienceDirect, 2014-08)
129I is a very long-lived radionuclide (T1/2 = 15.7 × 106 years) that is present in the environment because of natural and anthropogenic sources. Compared to the pre-nuclear era, large amounts of 129I have been released ...

Pattern imaging of primary and secondary electrohydrodynamic instabilities
(Cambridge University Press, 2006-02-08)
A little known electrohydrodynamic instability, which we call a rose window, is observed in air/liquid interfaces in electric fields with unipolar space charge distributions. Depending on the liquid properties, the rose ...

Anthropogenic 129I concentration and 129I/127I ratio in rainwater from Seville (Spain) in the period 2005–2008 as affected by airborne releases from Sellafield and La Hague facilities
(Elsevier, 2012)
129I is a very long-lived radionuclide (T1/2 = 15.7 × 106 years) that is present in the environment both because of natural and anthropogenic sources. In this work 129I concentration and 129I/129I ratio have been determined ...

Spatial modes of capillary jets, with application to surface stimulation
(Cambridge University Press, 2012-05-12)
Surface stimulation of any physical origin (electrohydrodynamic, thermocapillary, etc.) has the goal of generating localized perturbations on the free surface or the velocity field of a capillary jet. Among these perturbations, ...

Levels of 25 trace elements in high-volume air filter samples from Seville (2001–2002): Sources, enrichment factors and temporal variations
(Elsevier, 2015)
The measurement of trace element concentration in aerosols is of interest for environmental studies and for human health assessment. The temporal variability of total suspended particles (TSP) and its elemental composition ...

Geometric properties of the patterns observed in low conducting liquids under corona discharge
(ScienceDirect, 2008-03)
We describe an experimental investigation of the different patterns that appear in thin liquid layers subjected to strong electric fields and a corona discharge. The study is motivated by recent observations [F. Vega Reyes, ...

Structural effects due to the incorporation of Ar atoms in the lattice of ZrO2 thin films prepared by ion beam assisted deposition
(ScienceDirect, 2002-09)
Two sets of ZrO2 thin films have been prepared at room temperature by ion beam induced chemical vapour deposition and subsequently annealed up to 1323 K. The two sets of samples have been prepared by using either O2+ or ...

Pre- and post-Chernobyl accident levels of I-129 and Cs-137 in the Southern Baltic Sea by brown seaweed Fucus vesiculosus
(Elsevier, 2013)
129I is a very long-lived radionuclide (T1/2 = 15.7 × 106 years) that is present in the environment both because of natural and anthropogenic sources. In this work 129I concentration and 129I/127I ratio have been determined ...

Influence of alongslope processes on modern turbidite systems and canyons in the Alboran Sea (southwestern Mediterranean)
(Elsevier, 2019)
This is an interdisciplinary study that combines morphoseismics, sedimentology and numerical modelling to elucidate at different scales of resolution the influence of alongslope processes on the turbidite systems (TSs) ...
