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.

The pilots were required to expend the material, potentially for safety reasons, Nelson said, and received air traffic control permission to do so.
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.
In architectural acoustics, an enormous effort is expended to use construction materials that absorb undesirable frequencies but reflect desired frequencies.
The formula gives immediately accurate results for different vibrational modes and for various volume fractions of containing materials without expending much computational effort.
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].
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.
He wasn't one of those writers constrained by material imperatives to expend his quotidian energy on what he secretly repudiated as hack work, while dreaming of the masterpieces he would create if only he had the time.
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.
