To prevent disturbing the ink any further a float-washing technique was selected using two screens . Since random sampling techniques were not used in the survey , we cannot generalize the results to the larger nonprofit community . Environmental sampling techniques were conducted in the Hampton Roads area of Virginia in fish-processing facilities that regularly handle scombroid fish or other fish which are known to accumulate histamine levels greater than 50 ppm . Furthermore , it appeared that the development of child participation required communication skills and creativity to enable children and adolescents to express themselves , and that communication techniques were not developed enough among teachers and youth leaders . Random sampling techniques were not deemed necessary nor practical as it was possible to identify in each judicial division those judges who have had some experience in drug cases . The comprehensive survey design means that sampling techniques were not used . One area in which this project has contributed has been in the need to develop some commonly accepted methods for reporting of results , to allow for the comparison of different modelling techniques applied to the same data ( but the analysis being carried out by different researches in different institutions ) which has been fed into the SMT Project " European Network for the Intercomparison of Chemometric Software and Methods " All calibration models are sample dependent , which is why the implementation of experimental design prior to the modelling is so key , however in most industrial application an experimental design approach is not viable ( i.e. there is little or no opportunity to vary the plant in such a way as to provide data sufficient to meant the stringent needs of the DoE ) and as such most plant data is often quite low in variability . The isolation and affinity purification techniques were highly reproducible . Detailed procedures and sampling techniques were developed to preserve hardware and critical evidence , and a myriad of analyses were undertaken to determine the most timely and cogent methods for material determination of as-received deposits and prepared metallographic specimens . The most favorably rated communication techniques were electronic beepers and hand-held short-wave radios .
