As these experiments were conducted over long exposure periods (4 days), we must also consider that equilibrium may have been disturbed over time with the probable exudation of biogenic ligands that may have played a role in the speciation of Al.
As before/after studies are conducted over long time periods, the effects of general environmental (for example, antibiotic flora) and educational (for example, infection control awareness) changes are also difficult to account for.
Therefore, for more representative estimated recharge with a maximum deviation less than 20% from the 38-year mean value, research should be conducted over a long period (>12 years).
It in particular states that [s]elective and voluntary settlement programmes are believed to be the only viable options in the long run; as this change goes beyond a change of location for pastoral people and entails a drastic alteration in their cultural life, settlement will be conducted over a long period of time with the aid of training and initiative work (SDPRP 2000).

Since the rate of progression is slow, the trials must be conducted over a long period, preferably more than one year, to be able to detect changes.
16 They should also include comprehensive cost analyses, including health and social care costs associated with managing agitation as well as intervention costs, and be conducted over sufficiently long time horizons to measure the full costs and benefits.
Future research could be conducted over a time period long enough to ensure that the rare incidences where manual cleaning of endoscopes to be reprocessed with EVOTECH ECR could be included in order to examine the impact that the additional cleaning time would have on the overall cost comparison of EVOTECH ECR vs. an AER.
Phase IV (equilibrium-wetting phase), however, was not observed in the present systems even when the experiment was conducted over a long time.
First, a particular study may not have been conducted over a long enough time scale to detect recovery.
