In southern Australia, for example, declines in yield of 25 30 percent in second rotation radiata pine (Pinus radiata) plantations have been corrected by a number of means, including intensive silviculture (site preparation, weed control, fertilization) during the early stages, retention and management of forest debris (leaves, branches, etc).
With the exception of one study[ 42] it was possible to separate out the effect of each specific stage on retention.
Two theories for the origin of animal life cycles with planktotrophic larvae are now discussed seriously: The terminal addition theory proposes a holopelagic, planktotrophic gastraea as the ancestor of the eumetazoans with addition of benthic adult stages and retention of the planktotrophic stages as larvae, i.e. the ancestral life cycles were indirect.
They reported that the maxillary crowding decreased during treatment by 5.5 mm but increased (relapse) after the retention stage by 3 mm.
During the initial stage, the hydraulic retention time (HRT) of the reactor was maintained at 5 days with an organic loading rate of 2 kgCOday3 day.
Our group identified CAML as a Vpu-interacting protein through a yeast 2-hybrid approach, and expression and depletion studies revealed that CAML shared many of the same characteristics of a host restriction factor acting at the stage of particle retention [15].
Finally, the fourth window is represented by the periconception period and the zygote stage, when histone retention in certain genes could represent a potential mechanism for inheritance of environmentally induced epigenetic marks.
Since SPS has been shown to disrupt the retention stage of fear extinction [ 20], it is interesting to know whether ZIP may have an impact on SPS procedure, especially the depressive and anxiety-like behavior, representing the core symptom of PTSD-related abnormalities.
The proposed process comprises the following stages: metal ion retention, polymer regeneration and metal recovery.
Basically, it includes two stages: (1) metal retention, where we can obtain a permeate stream free of heavy metals; (2) polymer regeneration, where the polymer is regenerated in order to be reused in metal retention stage.
Organizational knowledge is gained from experiences in three stages: information acquisition, retention of experience, and retrieval of experience (Levitt and March 1988; Walsh and Ungson 1991; Meschi and Métais 2013).
