Some problems such as heat generation in specimen and frequency effect in ultrasonic fatigue testing are also briefly discussed.
The backscatter coefficient is computed and comparison is made with experimental data for 37 specimens and for frequency ranging from 0.4 to 1.2 MHz.
Finally, recommendations were made for the timing for specific staining of endomyocardial biopsy specimens and the frequency by which circulating antibodies should be assessed.
Consequently, we focused on the -271 G>A polymorphism in all of the specimens and analyzed the frequency of its genotypes (Fig. 1).
There was a statistically significant effect of loading frequency on a specimen's time to equilibrium and significant interaction of force and frequency on specimen thickness and time to equilibrium.
Higher N-surv positivity and frequency in specimens from younger individuals suggest ageing as a factor that may influence survivin expression.

Nearly constant and frequency independent characteristics of specimens have potential applications.
The apparatus is capable of adjusting the cyclic load and frequency applied on the specimens, whilst being submerged in a corrosive solution.
Origin of tench specimens with haplotype codes and frequencies.
The results of the experimental study showed that the changes to the specimens' natural frequency varied non-linearly with the cycle ratio or damage fraction, and that relatively large changes in the natural frequency could be measured near the end of the fatigue life.
