allow discontinuous trajectories such as hovering capabilities but may have payload, speed, power, flight time and endurance limitations (Hardin & Jensen, 2011), and any addition of an on-board air sampler must consider downward draft from rotor activity.
The design of a sample introduction system must consider the efficiency of the heat transfer from the plasma to the droplets, which is related to the power reaching the sample and the residence time of the droplets for the complete desolvation and volatilization in the plasma.
It is also possible that our findings are limited by the participating sample – that is, we must consider the question of whether or not the experts who were asked but did not participate held different views to those who did participate.
Cord blood has been recommended as the best available parameter (National Research Council 2000), but sampling of cord blood must consider that coagulation starts soon after clamping of the cord, and clinical circumstances may prevent blood collection in time.
If this relation was not evident, we supposed that the uptake of mineral elements was influenced by the plant genotype or by the stage of development, which are factors that can affect the characteristics of plants, since we must consider that samples were randomly collected.
However, the Helmholtz square shape coil generated the required magnitude and so the decision to choose this coil must consider both the sample volume under study and the ease of manufacturing them.
Evaluating the results we must consider the small sample size and our learning curve.
The results must consider the poor sample size, the short follow-up, and its features of being a retrospective and observational study.
As discussed in relation to the observed results for the longitudinality verified score, one must consider that the sample consists of hospitalized individuals and, therefore, the chance of finding an inappropriate utilization pattern was greater.
We must consider then the small sample size, that is not representative of the national attainment distribution.
