This lack of optimal mission opportunities can be seen in the small number of only 4 NEOs that meet all requirements for a sample-return mission and remain below an on-orbit mass of 500 metric Tons (mT).
The great ethnic diversity specifies the requirements for a population sample.
The thematic core collection obtained meets the minimum requirements for a core sample - maintenance of at least 80% of the allelic richness of the thematic collection, with, approximately, 15% of its size.
In food microbiology, requirements for a food sample preparation method are now well defined and can be specified as follows: i) reduction of matrix size for downstream steps without loss of target bacteria, ii) concentration of the target, iii) purification and removal of inhibitory substances, and iv) a low detection limit and constant recovery rate of the target [ 17].
Thus, the final sample may consist of any possible combination of individuals from the population meaning that the requirements for a simple random sample are satisfied.
Both discovery-driven and targeted approaches demonstrated a requirement for a larger sample size to fully characterize clinical response markers using a proteomic approach.
This may overestimate the sample size requirement, especially if the effect of the interaction is larger than the main effects, but it illustrates the general requirement for a larger sample size when interactions are introduced into hypothesis testing.
A separate integrated analysis of the subgroup of male patients from six clinical studies demonstrated a significantly greater improvement in the PAC-SYM total score in prucalopride-treated than in placebo-treated patients, providing support for the requirement for a large sample size to be able to detect this difference statistically (Shire, data on file).
Randomised controlled clinical trials of subjects receiving anti- Helicobacter pylori treatment have not been able to identify a significant reduction in gastric cancer because of the long time period during which gastric lesions are premalignant and the requirement for a large sample size.
The laboratory provided a handbook for practices containing instructions on the minimum requirement of data for a sample to be accepted and analysed.
