Finally, potential limitations of composite plans are discussed: a great number of field cores from an unbiased sampling plan have to be composited; comparisons between composites of unequal size should be avoided; all information on the variation among field cores is lost by compositing; parallel measurements of fauna and other variables in the same cores are not possible.
The national public health associations were given the greatest number of fields, and they positively checked the majority of options.
A greater number of fields were viewed for characteristics requiring assessment at higher magnification in an effort to grade a similar total area of tissue for each outcome.
This practice also helps test developers administer a greater number of field-test items embedded within multiple test forms.
A great number of tasks or duties that put individuals in contact with pesticides or pesticide residues, such as self-service and repair of application equipment among applicators and a greater number of field activities among workers, are associated with more exposure (Alavanja et al. 1999; Hernández-Valero et al. 2001).
We passed many cows and a great number of woods and fields and every twenty minutes or so the same farmer would appear, sitting in his wagon beside the village station, chewing tobacco and gazing thoughtfully at the Pullman windows.
The CRM produced lower estimates of biomass, visualized here as greater numbers of field plots with AGBM < 200 Mg/ha, and fewer large biomass plots, while the Jenkins and Chojnacky approaches produced approximately the same number of estimates per biomass density category.
It is believed that in the transition zone between the Arabian Platform and Zagros foreland basin, there should have been a greater number of oil fields similar to Azadegan oil field.
After that, a great number of mathematicians worked in this field and obtained a lot of results in metric and various abstract metric spaces (see, e.g., [5 10]).
The technology makes use of an even greater number of small fields with tiny leaves, or collimators, which can block parts of the treatment field.
