The coupling factors need a certain time to reach the new convergence levels.
In addition to this delay, new power plants are required to get permissions at stipulated LCD standard and they need a certain time to be constructed and to be brought online.
Motivated by the aforementioned observations, we assume the predator needs a certain time to gestate the prey, and we consider the following delayed Holling type III functional response prey-predator system with impulsive perturbation on the prey: left { textstylebegin{array}l} left.
Another method to measure productivity losses is the Friction Cost Method, which is based on the assumption that an organization needs a certain time span (friction period) to replace an absent worker with another worker.
The friction-cost method, which is recommended by the Belgian guidelines for economic evaluations, 3 is based on the idea that organisations need a certain time span (the friction period) to restore the initial production level after an employee becomes absent from work.
"The budget is how many people you need at a certain time," he said, "but the magic is deciding who is to work at what time".

In addition to the long incubation time needed, a certain level of auto-digestion of the protease can be expected.
We decided for file-based data packages because in the case of transmission failure, the long-term buffering is greatly simplified by storing the files on the local hard disk, and because the data post-management and evaluation is made much easier by just considering the needed files of a certain time period.
It serves a distinct need at a certain time, repeatedly.
Culyer and Wagstaff [ 6] suggest a definition of need relevant to economics: "the minimum amount of resources required to exhaust a person's capacity to benefit i.e. the costs necessary to satisfy a need during a certain time period (e.g. one year)".
