With a ratiometric probe, inaccessible zones would have no signal at either wavelength, whereas perfused regions with low enzyme activity would show strong FRET and thus be clearly distinguishable.
Diffusion-controlled mass removal from both the matrix and from the hydraulically inaccessible zones within the fracture itself result in extremely large time frames for significant mass removal from these systems.
Thus even when it proves impossible to survey Darfur's interior regions, researchers can use retrospective surveys in safe peripheral areas to gather vital, science-based information on events in inaccessible zones.
Out of the total 218 sub-areas, we investigated 143 sub-areas (66%) because the other 75 sub-areas were inaccessible zones, for example, fast flowing traffic avenues, private property, railway track, etc.
Ultrasonic guided wave tomography provides an imaging potential over a hidden and inaccessible damage zone.
An inaccessible attribute, without an equivalent property in the global ontology, cannot be accessed through queries.
Access to some of these zones, particularly A and B, depended on the alert level (0 through to 5; 5 being the highest alert level rendering zones A-D inaccessible).
When the October 8, 2005 earthquake hit Kashmir, Pakistan, I led a small team of volunteers to complete just one specific task: persuade our government to send more US helicopters to airlift aid to victims in the inaccessible disaster zone.
The mass and density arrangement of the cylinders creates a "band gap" in the structure--a zone of forbidden energies that are completely inaccessible to intruding waves from the outside, say researchers in the 15 June issue of Physical Review Letters.
It provides rare evidence of a conflict zone still inaccessible to independent observers.
The brainchild of a Pennsylvania dentist, the idea involved strapping small incendiary bombs to bats and releasing them to spread fires in inaccessible target zones.
