The relative conductance at room temperature of a solution in
kaolin membranes was studied as a function of the volume fraction of
the membrane. The resistances of the membrane and of the solution
were measured for various volume fractions, and the conductance of
the membrane relative to the solution was...
When the dc conductivities of various pure KC1 crystals were
compared it was found that crystals grown under an HC1 atmosphere,
from salt purified by ion exchange, exhibited lower knee temperatures
than any of the crystals studied. These knee temperatures
were found to be approximately 350°C. From this the total...
This paper develops an equation, from an heuristic set of assumptions,
which describes the axial current, leakage current, resultant
electric field, and resultant earth potential occurring when
a pipeline buried within a resistive earth is subjected to a distributed,
primary, axial, electrostatic field produced from a high-voltage, direct-current (HVDC) power...
Direct current conductivity measurements on KC1:O[superscript]= crystals
were used to determine an enthalpy of 0.42 ev for the dissociation for
anion-vacancy-oxide ion complex.
The entropy of dissociation was
found to be approximately -4x 10⁻⁴ev deg⁻¹. The intrinsic "activation" energy was found to be 1.91 ev as compared to 1.95 ev,...
The electrical conductivity of the pyromagmas from the Northeast
Crater of Mount Etna, Sicily was measured over the temperature
range 1032°C to 1071°C and over the frequency range 1 kHz to
400 kHz. Measurements were made using a four-terminal Wenner
array in conjunction with a Wavetek Model 110B portable signal...
A review of research conducted at OSU to determine compost value as a mulch or soil amendment for blueberry produced under conventional, transitional, or organic production systems.
From measurements of thermal and electrical conductivities of
64 ocean sediment samples obtained from piston cores taken off the
Oregon Coast, and from 37 water-saturated sandstone samples analyzed
by Zierfuss and Van der Vliet (1956), as well as 51 thermal
conductivities and water contents of ocean sediments analyzed by
Ratcliffe...
