life-period

Please be certain that you are not deceived by chronological age in this case and make provision for the sexual education this life-period demands.

Eve's Rib Chandler, Bryn 1989

A hydropower plant of 50 kW installed capacity at a cost of $ 1'500/kW ($ 75'000. - total investment) is planned for a life-period of 10 years.

As mentioned earlier, the IER needs a forecast of costs and revenues which then are related to each other and should produce some positive return on total initial investment over the life-period of the project.

So the first cost-benefit-level, by aggregating all cost over the life-period of the installation, determines a selling price of energy (which provides at least a cost-covering IER); the selling price must be related to given purchasing power (incl. the energy-induced increases of it) as well as to the selling prices of alternative energies and their revenue-increasing potential.

[12] The life-period of uranium is probably about eight thousand million years.

There were cycles: weaknesses and recoveries; on the whole its long life-period matters very little to history; it only became of great importance when it died.

An insect that is continually submerged and has no contact with the upper air cannot breathe through a series of paired spiracles, and during the aquatic life-period of the stone-fly these remain closed.

Conversely, if our life-period embraced myriads of æons, things which now seem permanent would then appear as in a perpetual state of flux.

The grains of each of these selected heads were [114] sown separately, and the lots compared during their whole life-period and chiefly at harvest time.
