Gas Kinematics on GMC scales in M51 with PAWS: cloud stabilization through dynamical pressure [PDF]

open access: yes, 2013
We use the high spatial and spectral resolution of the PAWS CO(1-0) survey of the inner 9 kpc of the iconic spiral galaxy M51 to examine the effect of gas streaming motions on the star-forming properties of individual GMCs.

Measurement of streaming potential coupling coefficient in sandstones saturated with natural and artificial brines at high selenity [PDF]

open access: yes, 2010
We report experimental measurements of the streaming potential coupling coefficient in sandstones saturated with NaCl-dominated artificial and natural brines up to 5.5 M (321.4 g L−1 of NaCl; electrical conductivity of 23 S m−1).

Saber: window-based hybrid stream processing for heterogeneous architectures [PDF]

open access: yes, 2015
Modern servers have become heterogeneous, often combining multicore CPUs with many-core GPGPUs. Such heterogeneous architectures have the potential to improve the performance of data-intensive stream processing applications, but they are not supported by

Ionic Fracture Fluid Leak-Off

open access: yesFluids, 2019
The study is motivated by monitoring the space orientation of a hydrolic fracture used in oil production. Streaming potential arises due to the leakage of ionic fracking fluid under the rock elastic forces which make the fracture disclosure disappear ...

Energy from streaming current and potential [PDF]

open access: yes, 2004
It is investigated how much energy can be delivered by a streaming current source. A streaming current and subsequent streaming potential originate when double layer charge is transported by hydrodynamic flow.

Ion Separations Based on Spontaneously Arising Streaming Potentials in Rotating Isoporous Membranes

open access: yesMembranes, 2022
Highly selective ion separations are vital for producing pure salts, and membrane-based separations are promising alternatives to conventional ion-separation techniques.

A New Modified Model of the Streaming Potential Coupling Coefficient Depends on Structural Parameters of Soil-Rock Mixture

open access: yesGeofluids, 2021
The streaming potential effect in soil-rock mixture (SRM) is related to the compactness and rock content, but there is no model to quantitatively describe this behavior.

Electrical streaming potential precursors to catastrophic earthquakes in China

open access: yesAnnals of Geophysics, 1997
The majority of anomalies in self-potential at 7 stations within 160 km from the epicentre showed a similar pattern of rapid onset and slow decay during and before the M 7.8 Tangshan earthquake of 1976. Considering that some of these anomalies associated

Streaming potential measurements 1. Properties of the electrical double layer from crushed rock samples [PDF]

open access: yes, 1999
The ξ potential has been inferred from streaming potential measurements with crushed rock samples as a function of pH and electrolyte concentration for various salts.
