Documentation includes specification of variables used , definitions of variables when appropriate , sampling errors and disclosure avoidance rules or techniques . Then , they incubate the cell sample that they want to study with this antibody / fluorescent marker . A set of utility routines is included to open serial devices , process sample data , edit input lines to extract embedded timestamps and to peform various debugging functions . Simulation analysis of particle size and a theoretical model of the phytoplankton package effect on fluorescence measurements by the dual fiber-optic sensor of the fluorometer indicated variability of fluorescence yield which were minimized by multiple sampling . The impact of perceived health on this population is a fruitful area for future research , especially using a nationwide sampling technique . The flow contribution from the wetland itself was estimated on an areal basis and combined with sampled chemistry to estimate solute fluxes . The appropriateness of the test to a particular null hypothesis and the interpretation of the results depend on the nature of the data at hand , in particular on the sampling scheme . Epidemiologic information was collected , and samples were sent to the USDA 's Foreign Animal Disease Diagnostic Laboratory . In a typical integration period of 1000 ms , some of the monitor points will be sampled 32 times and some 31 times . I hope you found these automation samples useful . We sampled 12 reservoirs during May - June , 1993 to evaluate the hypothesis that larval gizzard shad survival increases with reservoir productivity , reflecting postive effects of small zooplankton on larval gizzard shad success . Lowest abundances are usually restricted to the most seaward stations sampled along the shelf break and the central deep waters in the Gulf of Maine . More herds with 1 to 25 beef cows or 26 to 49 beef cows had positive samples , though prevalence by herd size was not significantly different ( Table 3 ) . Questionnaires were administered to 202 households from which 856 stool samples were collected . Asked for the proper management of demolition debris from a wastewater treatment plant that has lead based paint on several pipes and if there are any lead sample selection guidelines for demolition debris . It 's a research effort devoted to gathering rock samples beneath the oceans , to further scientists ' understanding of our planet . Now , here it is clear that you have a case of DST ending , however , what if the data were irregularly sampled ? Experiments with synthetic data sets show that an original generating distribution can be estimated from a sample . As shown above , the tolerable error rate is a key factor in determining sample size . Various questions pertaining to groundwater sampling at a site that may have chlorinated solvent environmental impacts .
