Although a theoretically feasible option, it is not logistically easy to infect animals with minor pathogens without, at the same time, increasing the risk of coinfection with major pathogens.
We chose that method of selection because random sampling was logistically awkward, and further, there was no obvious reason to suspect bias from the chosen method.
The influence of medication on cognitive function could be addressed through comparison of medication-free bipolar subgroups, although this would be logistically difficult.
In many ways, this would be the most logistically challenging volume of the set.
However, direct measures require the use of radioactive tracers, a procedure which ethically and logistically would have been unacceptable in the present study.
The precarious situation of the terrain vague as undefined politically and logistically requires and proposes new models of land acquisition, ownership and management.
Although the diet was easy to eat, it was expensive, logistically difficult, and probably too narrow to be optimal.
Although no doubt logistically challenging, estimates of l from experiments carried out under field conditions would therefore be very useful.
