There is, however, very little research related to how and why some policies have a long life and are maintained over time despite periodic threats to their existence; while others cease to exist.
"Seemingly random songs are maintained over time," Dr. Goodale noted.
These relations are maintained over a life span as long as 70 years.
Performance and energy benefits are maintained over a wide range of process-voltage-temperature (PVT) variations.
In the absence of Cl− the general surface topography and the (1 × 1) structure of the nonreconstructed surface are maintained over the entire upd potential range.
The studies were designed to investigate (i) the conditions under which chimpanzees learn from one another, (ii) how behaviors are transmitted, (iii) how cultures are maintained over generations.
Objective: to determine whether any differences in maternal satisfaction with the examination of a newborn baby between midwives and junior paediatricians are maintained over a three-month period.
By characterizing the ancestral proteins spanning the lineages of these two homologs, we gained insight into how properties such as stability, folding kinetics, and conformations change or are maintained over evolutionary time.
The Army plans to balance Carter's call for less red tape "while balancing appropriate process controls to ensure proper review and oversight procedures are maintained over constrained resources," Schwartz said.
The results were obtained as: under certain operation parameters, the rejection coefficients of both oil/water and turbidity are maintained over 0.96 and 0.97, respectively; while, temperature has no obvious effect on the rejection coefficient of oil/water and turbidity.
Broad sense repeatability, which refers to the extent to which individual differences in trait scores are maintained over time, is of increasing interest to researchers studying behavioural or physiological traits.
