Schwartz and Bilsky (1987, 1990) constructed a universal
psychological structure for cross-cultural studies of motivational
dynamics. To test this structure, Simmons (1991)
adapted data from a twenty year broad-based value survey of

Workers in colonies of European honey bees Apis mellifera L. clean their
nestmate's body by allogrooming behavior. This behavior may be initiated by
either grooming dancers or by the allogroomers themselves. The first occurs
less frequently (ca. 17 %) than the later (83 %). By using the inner edge of...
Hydrodynamic effects play important roles in fluidized bed
combustion processes. Since the motion of "bubbles" is an important
influence on fluidized bed heat transfer, a better understanding of their
behavior is necessary for improving the design of fluidized bed boilers.
Using a two-dimensional bed, silica sand particles were fluidized with...
