Though this fluctuation in depth was apparent, we found there was no significant difference [Mann Whitney U (MWU), P = 0.36] when one takes the depth between domesticated silkworms and wild ones into comparison.
This normalization, which is comparable to normalizations used elsewhere [71], corrected for normal fluctuations in anesthetic depth between measurements and inter-animal variability within a group.
Furthermore, fluctuations in pond depth give information on pumping rates, evaporation, precipitation and leakage.
In addition, micro-fluctuations of the accommodation also result in fluctuations in the depth position of the reference of the wavefront measurement [ 16, 30].
However, African rice often shows more tolerance to fluctuations in water depth, iron toxicity, infertile soils, severe climatic conditions and human neglect, and exhibits better resistance to various pests and diseases like nematodes (Heterodera sacchari and Meloidogyne sp ., African gall midge, RSNV and Rice yellow mottle virus (RYMV) [ 57- 61].
A correlation analysis of water quality and technical parameters revealed that pond depth (r=0.62), maximum fluctuation in pond depth (r=−0.55) and ammonia concentration (r=−0.63) were significantly correlated with shrimp yields (P<0.05).
All hydrologic parameters exhibited seasonality to some extent; fluctuation in water depth and groundwater inflows corresponded with the seasonal change in stage in WCA-1.
Sensory stimuli from without (such as noise or cold) or stimuli from within the body (such as dyspepsia or anxiety), plus a somewhat regular spontaneous fluctuation in the depth of sleep, will periodically (perhaps every 90 minutes or so) bring the sleeper into a state that favours perceptual release, in which case dreaming tends to take place.
In addition, two observation wells were installed to measure the fluctuation in the depth to the groundwater table.
