A large number of research results show that the accumulated AE ring count
is corresponding to the slip of dislocations, the initiation of microscopic cracks, and the expansion of macroscopic cracks in rock materials.
were made on both lapilli, the middle sized otolith, by the same observer using a 40X planapochromatic lens.
The frequency of the ring count
attains a peak for the different waste concrete contents; however, the specimens lose their support ability, the AE energy source from the broken blocks of the stripping off between the particles, and the friction.
Although it was sometimes difficult to find otoliths clear enough to reveal a continuous sequence of rings, daily ring counts
were completed successfully on otoliths from 208 Alabama shad from the Pascagoula River basin and from 53 Alabama shad from the Apalachicola River basin.
was determined using scanned pictures of end samples.
The ring count
was measured at each end and averaged.
When the radii of at least two successive rings of the first four visible rings each fitted well within one standard deviation from the mean radii of each of two or more rings from the data compiled from the younger specimens, the number of missing rings was computed as the difference between the ring counts
for the matched radii compiled from younger specimens and those for the specimen of interest.
This range demonstrates that the greatest variability in hardwood roundwood product prices is within the sawlog and veneer log portion of the market, and reflects the relative value of different species and the impact of growth characteristics (ring count
, color, consistency of ring count
, roundness of bole, etc.).
On the other hand, the index of completion, being the ratio of the marginal increment to the width of the previous band, would be expected to be constant at the same time of year for a particular species, regardless of the ring count
. Thus, during the maximization of the objective function
And based on a ring count
, it was approximately 200 years old--an emerging old-growth tree--when Mt.
For 48.1% of paralarvae, the concentric ring count
in the lateral wall of the upper beak equaled the number of days that they lived.
The ring count
(as rings per in.) was obtained by placing a ruler near the center of the end-grain face and counting the rings within a 1-inch distance.
