Some replenishment of existing weapons is required, but the military services are inclined to pour acquisition funds into incrementally improved versions of current airplanes, tanks and ships rather than look over the horizon at radically new ideas.
Since, inventory is assumed to start and end at zero, an extra replenishment at T m = H is required to satisfy the backorders of the last cycle in the planning horizon.
In the adult pancreas, Ngn3 expression is very limited, but levels rise during β cell neogenesis induced by pancreatic duct ligation, where Ngn3 is required for β cell replenishment (Van de Casteele et al., 2013; Xu et al., 2008).
These findings imply that an early COX-2/PGE2 signaling is required for the induction of stem cell-driven cardiomyocyte replenishment.
39 Oral iron is also unlikely to be adequate if a rapid effect is required, or if the rate of chronic iron loss exceeds the replenishment rate that is possible with oral administration.
Future studies should be aimed at determining the time that is required to return iron levels to their pre-exercise values and identifying factors that promote the replenishment of iron resources in athletes.
And as sea levels rise, replenishment will be required more often.
To maintain this amount of dust in orbit around Vega, a continual source of replenishment would be required.
Continuous replenishment of leaf litter may be required for long-term seedling culture.
Moderate-intensity running exercise requires a contribution from muscle glycogen (27, 28), of which the replenishment is of a high metabolic priority (21), with muscle glycogen depletion suggested to have a role in the development of postexercise hypoglycemia (29).
