Numerical investigation becomes a highly demanding tool for the best design in engineering. With one validated numerical result available, further is possible to conduct. Especially, expensive and limited access civilian conduct test like blast experiment. capability of Arbitrary Lagrange Euler (ALE) solver coupling approach between structure air AUTODYN, detail three-dimensional assessment RC ...

Shock waves are one of the primary damage parameters an ammunition explosion. Therefore, accurately obtaining shock wave pressure distribution law after explosion is greatly significant for power evaluation and guidance selection in operations course. This study established mapping function between surface reflected free-field pressures, considering altitude effect on pressure. Finite element n...

White-rot fungus Irpex lacteus degraded TNT significantly in proportion to the culture time. After 48 h incubation, about 95% of TNT was degraded. Two reduced metabolites were identified as 4-amino-2,6-dinitrotoluene (4-ADNT) and 2-amino-4,6-dinitrotoluene (2-ADNT) which was further degraded.

Trees belonging to the genus Populus are often used for phytoremediation due to their deep root formation, fast growth and high transpiration rates. Here, we study the capacity of transgenic hybrid aspen (Populus tremula x tremuloides var. Etropole) which expresses the bacterial nitroreductase gene, pnrA, to tolerate and take-up greater amounts of the toxic and recalcitrant explosive, 2,4,6-tri...

Purified CO dehydrogenase (CODH) from Clostridium thermoaceticum catalyzed the transformation of 2,4,6-trinitrotoluene (TNT). The intermediates and reduced products of TNT transformation were separated and appear to be identical to the compounds formed by C. acetobutylicum, namely, 2-hydroxylamino-4,6-dinitrotoluene (2HA46DNT), 4-hydroxylamino-2,6-dinitrotoluene (4HA26DNT), 2, 4-dihydroxylamino...
