Vibration-induced rotation
… a mechanical mechanism dubbed Vibration-Induced Rotation, or VIR. The tendency of threaded fasteners to move under the influence of vibrations is well known, but never before has the root cause been identified and investigated in search of beneficial consequences. The sense of rotation, speed, …

Mental rotation and sexual orientation
Mental rotation, a type of visuo-spatial ability, is the ability to imagine a figure rotating in space without verbal mediation. Gender differences in the performance of mental rotation tasks are well documented but the relationship between sexual orientation and mental rotation is uncertain. This …

Groupoid Models of Irrational Rotation Algebras
… construct certain groupoid models of irrational rotation algebras and show how this can be used to to find projections in the algebra.

CHILDREN'S MENTAL ROTATION: COMPETENCE AND PROCESS.
… This research combines these approaches. Mental rotation (the ability to mentally rotate objects) was examined by focusing on the developmentalists' concern for age of acquisition of this ability and the information theorists' attention to stimulus factors influencing this competency. Sixty …

Rotation and magnetism in massive stars
Rotation has a number of important effects on the evolution of stars. Apart from structural changes because of the centrifugal force, turbulent mixing and meridional circulation can dramatically affect a star's chemical evolution. This leads to changes in the surface temperature and luminosity as …

Ab initio Calculations of Optical Rotation
… focus on the theoretical prediction of optical rotation. This property, also referred to as circular birefringence, is inherent to all chiral molecules and occurs because such samples exhibit different refractive indices for left- and right- circularly polarized light. This thesis focuses on the …

On Projective Characters of Rotation Sub- Group
… with Weyl group W( £), and let W+{<f) denote its rotation subgroup. In [173 » the projective representations of the rotation subgroup W ( 9) have been determined from those of W( $) for each root system $. This is done by constructing non-trivial central extensions of W ( $) via the double …
