Based on the automated image analysis of twenty-four specimens, the difference in air voids between top and bottom layers decreased when specimens were compacted on both ends.
As performance characteristics of specific tests are generally based on high quality specimens, the difference of approximately 40% is likely linked to any one of many operational procedures that affects the quality of the specimen and its procurement.
One interesting point is that, for the unequally notched specimen, the difference between the crack tip triaxial stress for tension and that for bending increases significantly with the increase in the back angle.
Additionally, to understand the microstructural basis for this difference in performance, broken specimens were examined using both scanning (SEM) and transmission (TEM) electron microscopy.
These two specimens had difference of 6.0 % in the first cracking load, 0%% in the serviceability load, 1.3 % in the ultimate load, and 2.6 % in the energy absorption.
In 14 of the 19 specimens, the total-BMD was reduced after thawing; in three specimens, the total-BMD increased after thawing; and in two specimens, no difference was observed.
It is therefore possible that at least some of the differences in the data obtained with the different investigations resulted from differences between the specimens rather than differences in the methods.
Percentages of this CD4low+CD25bright+ population were low in the blood and the pleural fluid in each group, accounting for less than 5% in virtually all specimens, without significant difference among the 4 groups studied (p = 0.17).
This could be related to a different baseline level of OXPHOS activity in various tissues and cancer specimens and/or differences in tissue handling.
Apatosaurus had a thicker neck than the original Brontosaurus specimens, and differences were seen in the shape of their shoulder blades and ankle bones, according to the PeerJ report.
