Crude oil must first undergo cracking and then reformation, both of which are energy intensive and costly.
Under the combined influence of an aggressive environment and applied stress, engineering thermoplastics may undergo a phenomenon known as environmental stress cracking (ESC).
The global domain of interest can include a moving or deformable subdomain that furthermore may undergo topological changes due to, for example, crack propagation.
Under the combined influence of a thermal and applied stress, engineering thermoplastics may undergo a phenomenon known as thermomechanical fatigue or as environmental stress cracking.
These then may undergo further reactions.
An adenoma may undergo cystic degeneration.
Each dissolved component may undergo first-order decay and may sorb under local equilibrium conditions.
He's been undergoing chemotherapy since October, and may undergo surgery in February.
This mechanism is primarily responsible for the superior mechanical properties of zirconia, since it may undergo phase transformation from tetragonal to monoclinic under localized stress, with a subsequent increase of about 4 to 5% of local volume, inhibiting crack propagation [ 9, 23].
It is anticipated that ethane will undergo more cracking when passed through a longer reaction zone (longer retention time).
