The nitrogen incorporation ranges from 150 nm (at 550 °C, whatever the duration), up to more than 500 nm (770 °C) thanks to temperature activated diffusion.
Albalá-Hurtado et al. [4] investigated the formation of HMF as a result of exposure to different storage temperatures (20, 30, 37 °C) and storage duration (up to 9 months) in liquid as well as in powdered infant milk.
Definitive prevention trials with cancer endpoints, such as the Breast Cancer Prevention Trial (BCPT), Prostate Cancer Prevention Trial (PCPT), and Selenium and Vitamin E Cancer Prevention Trial (SELECT), require long trial duration (up to 12 years) and large sample size (up to 32,400 subjects) to accomplish their objectives.
The design ensures the stability of the gain and of the base line for events made of several pulses over a long time duration (up to 20 μs) and a total charge ranging from a few to 6×105 photoelectrons (typical value: a few thousands) with a peak photocathode current of up to 200 nA.
For example, in the CLS scenario, the typical life cycle of a car may have duration up to several weeks and usually it is affordable for a user-centric system to take up to half a minute to produce a solution.
We aimed to conduct our tests on a broad (subregional) scale and with extended duration (up to 12 months).
Recent cohort studies indicate a prolonged duration (up to 10 years) of the negative predictive value of HPV testing.
Figure 6 summarized SEM pictures and nC+ current according to duration (up to 6 h) of heating at 525 °C.
The longer-term safety profile of tocilizumab (mean treatment duration, 2.4 years) is consistent with that observed in the phase 3 studies (duration up to 1 year).
Two slightly increased risk estimates were observed (OR about 1.2, only marginally significant): duration up to 2 years and 8+ years.
Japanese researchers have argued that psychosis induced by amphetamines could, in fact, be of much longer duration, up to several years [ 64- 66].
