High temperature triggered multiple-shape memory poly(benzoxazole-co-imide)s with adjustable properties were prepared via facile random copolymerization 3,3′,4,4′-biphenyltetracarbolylic 3,3′,4,4′-biphenyltetracarbolylicrent dianhydride4,4′-oxydianiline (ODA) and 5-amino-2-(4-aminoBPDAene) benzoxazole (BOA).
Higher temperatures trigger bond reconstructions in defective CNTs and bring relief to the negative effects of the defects, thereby improving the torsional capacities of the defective CNTs.
However, acid treatment at high temperature (80°C) triggers CGN hydrolysis to lower molecular weight (<50 kDa) compounds known as poligeenan or degraded CGN (dCGN).
Raising trapped completion fluid to a high temperature can trigger high thermal stress, and this stress has been proven to present a grave threat to the safety of deepwater wells.
By manipulating the temperature experienced by Phratora vulgatissima females, we found evidence for the hypothesis that high temperature can trigger latent variation in egg-laying capacity among insect individuals.
The results suggested that a high night temperature triggered thousand of transcripts to differentially express in the heat-tolerant and -sensitive lines, but only 35 transcripts showed a significant difference (RFC ≥ 2.0) in gene expression between the two lines.
As a basis for the modeling we first tested the hypothesis that high temperatures can trigger latent variation in oviposition rate among individual females.
Though that might not seem like much, a temperature rise of 1.8 to 3.6 degrees above the average high temperature for the summer can trigger bleaching in many reefs.
The researchers pored over days-long extremes in heat stress--a double whammy of high temperature and humidity that can trigger heat strokes in the elderly and other vulnerable people.
The FIRE response was not restricted to nutrient stress, as it could be triggered by high temperature and oxidative stress (not shown).
