Jephtha spent the late morning and early afternoon visiting government departments in search of usable material.

Mr. Guttentag said his crew shot 390 minutes for every one minute of usable material.

From a one-hour session he had 22 minutes of usable material, 12 songs, none longer than 2 minutes.

Thus, not all the lead is returned to the battery plates, and the amount of usable active material necessary for electricity generation declines over time.

These may come from a different tradition or may indicate a differences in design caused by the availability of usable materials.

Swedish forces had mostly just withdrawn before the advancing Russian often destroying usable materials.

Within weeks, Vincennes residents had stripped the fort of all usable materials.

Plus, you almost never run out of usable materials.

We expect a river to serve as both vein and artery carrying away waste but bringing usable material in the same channel.

The Soviet military then stripped all usable materials from the building.
