This numerical study on the reinforced concrete structures subjected to blast loads has significant benefits over experimental investigation, given that repetitive blast tests accompany enormous cost and time.
However, in the primary leukemic blasts tested in this study, basal levels of p-Erk, p-Akt, and p-S6 did not differ significantly between FLT3-ITD and FLT3-WT blasts (Figure S3A).
The first mock-up was subjected to a blast test in Socorro, N.M., at the Energetic Materials Research and Testing Center, a division of the New Mexico Institute of Mining and Technology.
But he said in an interview that the blast tests "demonstrate very clearly" that the chimney could offer protection well beyond what the Army was expected to seek.
The Pentagon will conduct five more blast tests, and the Army could request bids this fall for a new version of the Humvee.
James McAleese, a military consultant in McLean, Va., said the bolt-on armor, which is easy to replace if it gets damaged in the field, performed well in blast tests and also increased Oshkosh's score.
"Some of this stuff could be done by a good high school science fair student," said Douglas Olson, a chemist who manages blast testing at Wilfred Baker Engineering in San Antonio, Tex.
Pentagon officials have said little about the 11 blast tests so far, in which the prototype vehicles are engulfed by a cloud of smoke, dust and fire, but the passenger cabin remains intact.
But recent blast tests show that Humvees built with the new chimney could provide as much protection as some of the heavier, and more costly, mine-resistant vehicles that have replaced them in many uses.
