This research also demonstrates that the high cost of operating pressurised kerosene lamps precludes them for use in other applications within the community, including in homes.
While silver and gold have excellent reflectivity above 1 µm, their low efficiency in the UV precluded use for this application.
Detection of any neutralizing activity to either SLEV or WNV within the serum of any crow precluded use for experimental inoculation.
The scarcity of silver, combined with its softness and malleability, precluded its use for making tools.
The unavoidable spatial inhomogeneity of the static magnetic field generated by open sensors has precluded their use for high-resolution NMR spectroscopy.
This type of study is impossible in humans due to obvious ethical considerations and the cost and complexity in working with primate models has precluded their use for extensive studies of the exoerythrocytic stage.
Suboptimal completeness and quality of documentation of individual case-sheets however precluded their use for any cross-verification.
TreeMap was not used in these experiments because the exponential time and space that it requires precluded its use for most of the problem instances.
