As soon as we consider cellular dynamics, development, or evolution over a large-enough time span, the organisation of the underlying regulatory system starts to change.
If you live until 95, that means that what you saved in your working life needs to last for 30 years past your retirement at 65. Since people work about 40 years before they retire, saving enough in that time span to live comfortably for almost that 40 years isn't easy.
Another idea would be to require specific issue polls to put questions into different forms, from different angles which should also be published, to be sure the question is not leading, and over enough of a time span to offer more than a momentary peek at opinion in response to breaking news.
If the web is thin enough, in a certain time span, the nominal reel radii can be considered as constants and the reel eccentricities are periodic.
But the book spans enough time for Karen's heroism to become something quite different in the eyes of this daughter.
For the sample prepared at 200°C, a 6-h time span was enough to get high purity peaks.
The three species of bank voles diverged a few million years ago (∼4 My for M. rufocanus and ∼3 My for M. glareolus – M. rutilus; [32], [33]), a time span long enough to accumulate such differences in the basic properties of the sequential development of the triangles.
For instance, depression maintenance trials are normally conducted over a time span long enough to make a recurrence in untreated patients likely, or dementia trials cover a period, where a progression of the disease is to be expected.
Number of months since outbreak finished, plus 11 months (maximum decay time for maternal antibodies), plus zero to 12 months (a time span short enough to exclude most previously infected animals, although a shorter interval could be used if necessary).
