Two groups of endoscopic biopsy specimens were examined, including 20 endoscopic biopsy specimens of short-segment Barrett esophagus (Group A) and equal number exhibiting Helicobacter pylori associated intestinal metaplasia of the gastric cardia and corpus (Group B).
In this study, six specimens of STRC and STSRC short columns were experimentally tested under constant axial compression and cyclic lateral load to investigate the seismic performance of both kinds of structure.
For all tested specimens, the propagation of short cracks occupies a significant portion of the fatigue life.
Je values of short specimens cut from 100-m-long PAIR tape are 380 450 andm2 and 330 390 atmm2 at 4.2 K in 22 T and 30 T, respectively.
Accompanying mechanical tests of short specimens (30 mm) were also carried out to obtain compressive strengths of the GRP material at elevated temperatures.
But Aristophanes belongs to the end of this phase, and, indeed, his last extant play, which has no choric element at all, may well be regarded as the only extant specimen of the short-lived Middle Comedy, which, before the end of the 4th century bce, was to be superseded in turn by the milder and more-realistic social satire of the New Comedy.
Crack density increased as much in specimens fatigued short of the failure point as in those that fractured, and microcracks were, on average, shorter in specimens with greater numbers of resorption spaces, a measure of remodeling rate.
Cylindrical specimens with three different percentages of short and fine fibers 0%, 1.5% and 3% by volume of concrete are firstly fabricated.
The so-called load increasing testing technique was applied on notched bending specimens and allowed for initiation of short micro cracks.
Fluorometric techniques offer the opportunity to quantitatively investigate a high number of specimens in a short period of time and, at the same time, provide reproducible and significant data [25].
