In the present paper, we have investigated the performance of light obscuration, flow microscopy, and Coulter counter instruments for particle counting and sizing in protein formulations.

Multivariate Behav Res

January 1975

This study investigated the generality of the perceptual factors of speed and flexibility of closure in the cognitive domain. Several experimental measures of both flexibility and speed of closure employing perceptual or figural content, verbal or symbolic content, and semantic content were administered to 541 Naval Aviation Cadets, along with marker measures for several established factors. In addition to several of these marker dimensions, factors were obtained for both flexibility and speed of figural closure, of verbal or symbolic closure, and of semantic closure, along with a dimension tentatively interpreted as flexibility of grammatical closure.

Individual scores on these viewpoint dimensions were found to be significantly correlated with certain cognitive and personality measures.
