Threat assessment modules are disclosed that intelligently review evidence of potential threats posed by detected objects within a region of exo-atmospheric space and generate a most probable threat scenario to facilitate administration of counterspace operations. The vacuum device comprises an inner tubular member slidably engaged with an outer tubular member with a sleeve member disposed inside the inner tubular member. More specifically, the expanding monomer used in this composition is one or more dioxiranyl tetraoxaspiro5. Yet another apparatus separately positionsmoves two different attachment points on the object within the bounds of the lateral faces of a three-dimensional space having the shape of a convex prism. The method was found to be useful in the reduction of hexavalent chromium to trivalent chromium at a Superfund site.
