Other studies have already reported a relationship between apical or radial incremental growth and rainfall on different time scales (day, month and season) in different species [ 87- 89].
For example the time scale ranges from seconds (adrenalin) to years (growing up), or may have a pulsatile component, again in different time scales (day-night rhythm, monthly cycle).
This body of research will contribute to an improved understanding of the functioning of the coupled West African system, and enhance our ability to model and predict rainfall, vegetation and biogeochemical dynamics across time-scales (day, year, decade, and century), and in response to changing climate and land use.
On a geologic time scale, a day and a century are roughly the same unit, but for the purposes of a news cycle, the difference is crucial.
The first time scale is day-ahead economic optimization of a whole day, and the second time scale is heat load adjustment in a particular period to ensure accuracy and efficiency. .
The first time scale is day-ahead economic optimization of a whole day, and the second time scale is heat load adjustment in a particular period to ensure accuracy and efficiency.
Based on the forecast load and energy supply of the system, the first time scale is day-ahead economic operating optimization, carried out to determine the minimum operating cost for the whole day, and to find the period of greatest cost to which the second time scale optimization is applied.
The RXTE data confirm the strong absorption corresponding to the optical depth to electron scattering of about 2, but also reveal rapid variability of the hard (8 – 30 keV) X-ray emission on a time scale of a day or less.
In this framework, multiple crude-cell extracts are selectively enriched with individual pathway enzymes, which are then mixed to construct full biosynthetic pathways on the time scale of a day.
Wu et al. (2009b) analyzed the spectral ratios between a pair of on- and off-fault stations along the North Anatolian fault after the 1999 Düzce earthquake in Turkey, and they found that the fault zone site response dropped ~20 40 percentt and recovered with time scale of ~1 day.
