Exposing engineered materials (e.g., various steel alloys and grades used in pipelines, tanks, valves, ships, and railcars) to new fuels can produce unanticipated environmental degradation of the material, which may result in equipment failures.
The frustration comes from a long and winding history of fans living with and growing with their favorite heroes and villains, only to see their co-creations being changed in sharp and unanticipated ways that dismiss decades of material.
As products using platinum nanoparticles become more familiar in our daily lives, the chances of exposure to platinum nanoparticles are increasing, as are concerns about unanticipated harmful biological effects of these materials [17, 18].
However, because nanomaterials possess novel properties that are different from conventional materials, concerns about their potential unanticipated effects have been raised.
A role for the pericentriolar material in centriole cohesion is not unanticipated, and pericentriolar material disassembly upon mitotic exit (potentially mediated by separase in some organisms [ 29, 30]) presents an attractive mechanism to coordinate centriole separation with the cell cycle.
With a $38 billion increase, however, the beefed-up OCO account would make up nearly 15percentt of the Pentagon's $612 billion budget, and would pay for materials and training not tied to unanticipated increases in the cost of the two wars, which was the account's original purpose.
