"a decline phase" is a correct and usable expression in written English.
You can use it to refer to a period of decreasing activity, level, or overall performance. For example, "The company experienced a decline phase following the financial crash of 2008."
Performing the microcalorimeter, the normal metabolic thermogenic curve of E. coli growth in the LB culture medium at 37 °C in the absence of any substances was determined in Fig. 1, which presented two stages and four representative phases: the first exponential growth phase (A B), a stationary phase (B C), the second exponential growth phase (C D), and a decline phase (D E).
From 45 h, growth ceases (entry to stationary phase) and we assist to a decline phase (death phase) that was may be accentuated by the high ATPase activity of the produced US417 phytase as previously demonstrated for the native PHY US417 enzyme purified from the B. subtilis US417 strain (Farhat et al. 2008).
Today, these reservoirs are still important hydrocarbon producing fields with accurate reservoir description and 3D modelling capabilities playing a vital role in targeting remaining oil, especially now that many of the fields on the Norwegian continental shelf are past peak production and are in a decline phase.
After 168 h, there was a decline phase or cell death, which showed a drastic decrease in density and cell viability.
At the three lowest force levels (unloaded, and loaded 5 and 10% MVC), the CV had two phases: a decline phase lasting for about 120 150 s and a steady phase continuing to the end of a test.
We investigate selective sweeps with four different starting times (t0) at which the successfully sweeping allele first arises within a cycle: t0 = 0, t0 = 0.25Δ T, t0 = 0.5Δ T, and t0 = 0.75Δ T. These four cases describe, in order, a starting time of the sweep midway during a growth phase, at the end of a growth phase, midway of a decline phase, and at the end of a decline phase.
And maybe we're just in a declining phase now, and we're going to continue on that inevitable path that will lead us to a different place than the kind of country we grew up in.
He found that momentum gains were present and significant in these countries, and regardless of whether the economic cycle was in an upswing or a declining phase, the momentum gains were significantly positive.
For a declining phase of the solar cycle 23 during the year 2005 2008, the study shows that the IRI foE prediction is similar to the foE observation during the period of 2005 2008.
For a declining phase of the solar cycle (2004 2006), the study shows that the IRI-2007 TEC underestimates the IRI-2007 TEC with the foF2 observation at the nighttime by about 5 TECU.
Parasites inoculated into RPMI reached stationary phase (~7.1×10/ml) within an average of 4 5 days followed by a declining phase (~5.6×10/ml) between the sixth and ninth day.
