Nevertheless, the Navy is requesting permits to use live ordnance including bombs, missiles, and torpedoes, along with active and passive sonar in "realistic" war-training exercises that could release as much as 352,000 pounds of "expended materials" into those waters including, according to the Navy's own Environmental Impact Statement (EIS), missiles, bombs, and torpedoes.
Subsequently, many state transportation departments have begun to question the sensibility of expending material and personnel resources to maintain ice warning signs when little proof exists of their effectiveness in improving highway safety.
3-D entrepreneurs are particularly bullish about additive manufacturing, because the process requires as little as 10percentt of the raw material expended in traditional manufacturing and uses less energy than conventional factory production, thus greatly reducing the cost.
Additive manufacturing also saves tremendous costs, requiring as little as 10% of the raw materials expended in traditional manufacturing and eliminating the need for inventory.
Talent is evident, great ingenuity has been expended to shape challenging material into satisfying form, and still the results fail to stir the kind of excitement that musical theater can ignite.
In her view, once the social realm has established its monopoly, the distinction between labor, work and action is lost, since every effort is now expended on reproducing our material conditions of existence.
For this reason, in recent years a great deal of effort has been expended to use natural materials as benign reagents in nanoparticles synthesis [6, 7, 8, 9].
Impact performance can in some way be measured by the energy absorbed or expended to failure of a material.
The authors concluded more effort must be expended on procedures and written materials, to ensure that women are better prepared and that the information flow throughout the care chain is reliable.
Recently, much research interest has been expended on the ferromagnetic iron oxide materials generally used for magnetic data storage as magnetic toners in xerography, and on the ferrofluids, used as contrast agents in magnetic resonance imaging [MRI] [10 13].
