Most importantly, after 200 cycles of severe abrasion, they were able to restore the superhydrophobicity by brief heating treatment and showed excellent self-healing ability.
A test model made of Mod.9Cr 1Mo steel was subjected to 1873 cycles of severe thermal transient loading using a large-scale sodium loop, in which elevated-temperature sodium at 600 °C and 250 °C was flowed repeatedly and kept at the final temperature for 2 and 1 h, respectively.
The tubesheet model made of Mod.9Cr 1Mo steel was subjected to 1873 cycles of severe thermal transient loads using a large-scale sodium loop, in which sodium heated to 600 and 250 °C was flowed repeatedly with periods for each transient of 2 and 1 h, respectively.
Thailand experiences hyper-endemic DENV transmission, with seasonal cycles of severe disease that erratically vary in magnitude across provinces and from year to year.
Our study took place in Burundi, a country that, since its independence in 1962, has experienced recurrent cycles of severe interethnic violence [ 39].
In all cycles, incidence of severe neutropenia was lower with lipegfilgrastim 4.5 and 6.0 mg versus pegfilgrastim and lipegfilgrastim 3.0 mg (data not shown), reaching significance versus pegfilgrastim in chemotherapy cycles 2, 3, and 4 (P < 0.05).
However, mutations have been found in genes regulating the progenitor cell mitotic cycle in several types of severe congenital microcephaly (Thornton and Woods, 2009; Yu et al., 2010; Castiel et al., 2011; Kalay et al., 2011).
A cycle emerged: A feeling of severe stupidity would be followed by intense reading, followed by another period of feeling stupid as I realized that, no matter how much I read, new gaps in knowledge would keep popping up.
