Despite this fact, the baseline knowledge of species composition needed to monitor biodiversity change is limited for most animal groups.
A ≥ 309.6 cm layer with the optimum composition is needed for satisfactory longevity, defined here as meeting the Grade III criteria (the Chinese National Bureau of Standards: GB/T14848/93) for in situ treatment of the sampled groundwater for ≥ 10 years.
The high-K+, low Na+, low Ca2+ endolymph composition is needed for proper auditory and vestibular function [ 1- 3].
Clearly, comparisons of groups of different age composition are needed for a better understanding of the factors influencing male mating success in Barbary macaque males.
The shift in the isoelectric point due to changes imposed in brine composition needs to be accounted for in addition to brine pH and salinity in order to optimize recoveries from low-salinity waterfloods.
Because of the quantity of information needed for composition, the six-channel Teletypesetter tape is being increasingly replaced by seven- and eight-channel tape.
For the fabrication of the insulation a long pot-life of the resin is of great importance, which is mainly determined by the amount and the composition of the catalyst needed for curing the resin.
These results enable the selection of ARS compositions and acoustic parameters needed for optimized spatiotemporally controlled release.
But this method is unsatisfactory: one cannot conclude, for example, from his allusions to the law that Shakespeare was a lawyer, for he was clearly a writer who without difficulty could get whatever knowledge he needed for the composition of his plays.
Where a component is no longer needed for any composition, it may be removed using the removeComponent method.
