It has been found that pre-test simulations with only coupon data as input are capable of providing a reasonable overall representation, but to closely match the behaviour of the test, a significant amount of post-test work is required.
Popular methods central to this process are based on cross-correlation, and it has been found that pre-whitening the signals prior to determining the cross-correlation function has certain advantages.
It has been found that pre-stressing samples at 0.95 of the 0.2% proof stress leads to early failure when they are fatigue-tested at stress levels of about 0.65 of the 0.2% proof stress.
It has been found that pre-exposure annealing at 600, 700 and 800°C affected the distribution of α phase that precipitated following subsequent exposure at temperatures between 450 and 550°C.
There have been a number of studies looking at protein selectivity in pregnancy, which have not found a correlation between the level of selectivity, and the underlying renal pathology although it has been found that pre-eclampsia shows intermediate range selectivity and is never selective [ 3– 6].
It is found that pre-treatment time and process temperature tune the density as well as the shape and the structure of the grown carbon nanotubes.
It was found that pre-treatment of the catalyst with an alkyne such as trimethylsilyl acetylene or ethynyl aniline (that did not give fiber growth), followed by treatment with acetylene initiated fiber growth morphologies (Y-junction, helical or straight fibers) different from that observed after direct treatment with acetylene.
Based on a NTG-induced migraine model, it was found that pre-administration with VPA would alleviate the damage due to migraine attack.
Intriguingly, when subjects with mucosa-associated lymphoid tissue lymphoma were examined for antibodies to the H. pylori hsp60 chaperone it was found that pre-treatment titers in patients whose tumors regressed after treatment were significantly higher than in patients whose tumors did not regress [24].
It was found that pre-emptive vaccination (coupled with social distancing) remained the most cost-effective strategy for pandemic return times up to 80 years.
It was found that pre-seniors living in the community reported more oral health impacts than seniors even though the oral health of pre-seniors was better than that of seniors [ 23].
