From the eighteenth century landowners had recognised the need for effective techniques for draining impermeable clay soils.
However, although the seed coat remained impermeable, and so imbibition was not possible, there appears to have been a response to the high external humidity.
The degree to which septate junctions may render a cell layer impermeable appears to be highly variable.
The theory has been applied to both impermeable and porous stationary and moving journal-bearing systems.
We investigate the propagation of the two fluid layers along a horizontal, impermeable boundary of a porous layer.
These shallow wells are apparently made possible by the presence of perched water tables that rest on impermeable geologic strata.
The chalaza, where the ovule was attached to the fruit, was the last portion of the seed to become impermeable.
Crudely speaking, the channel itself may be viewed as a pipe (cylinder) embedded in an impermeable membrane.
There was a general positive correlation between proportion of fresh seeds with impermeable coats and thickness of the water-impermeable and mechanical layers.
The five species presenting impermeable seed coats do not manifest identical behaviour.
A possibly longer storage period in the second year might have resulted in dormancy loss and in a corresponding decrease in percentages of impermeable seeds.
In this paper the problem on the impermeable parachute of optimum shape in a subsonic gas flow is solved.
Outcomes of children receiving the intervention prove that this pathway can be altered and is not impermeable.
However, other studies have shown that soil microbes have no effect on rendering impermeable seeds permeable.
Physical dormancy means the seed (or fruit) coat is water impermeable.
