Using an α decay level scheme, the fine structure in odd nuclei is explained by taking into account the radial and rotational couplings between the unpaired valence nucleon and the core of the decaying system. It is shown that the experimental behavior of the α decay fine structure phenomenon is governed by the dynamical characteristics of the system.

The rheological properties of a zinc phosphate and a zinc polyacrylate cement were investigated using a rotational viscometer. The effects of time, temperature, shear rate, and spindle geometry on the measured viscosities were evaluated. Results indicated that both cements exhibited Newtonian behavior.

In this paper, we analyze and demonstrate a novel rotational energy harvesting generator using gravitational torque. The electro-mechanical behavior of the generator is presented, alongside experimental results from an implementation based on a conventional DC motor. The off-axis performance is also modeled. Designs for adaptive power processing circuitry for optimal power harvesting are presen...

UNILATERAL injection of 6-hydroxydopamine (6-OH-DA) into the dopamine (DA) cell bodies in the substantia nigra of a rat induces a degeneration of the entire nigro-striatal DA neuron system (Ungerstedt, 1968, 1971a). The lesion causes the animal to deviate in movements and posture towards the lesioned side (Ungerstedt, 1968, 1971b). Due to the high specificity of the 6-OH-DA induced lesion (Unge...

Stabilized wave segments in the photosensitive Belousov-Zhabotinsky reaction are directionally controlled with intensity gradients in the applied illumination. The constant-velocity waves behave like self-propelled particles, and multiple waves interact via an applied interaction potential. Alignment arises from the intrinsic properties of the interacting waves, leading to processional and rota...

Random interactions are used to investigate to what extent the low-lying behavior of even-even nuclei depend on particular nucleon-nucleon interactions. The surprising results that were obtained for the interacting boson model, i.e. the dominance of ground states with L = 0 and the occurrence of both vibrational and rotational structure, are interpreted and explained in terms of a mean-field an...

We discuss the relevance of chaotic scattering in heavy-ion reactions at energies around the Coulomb barrier. A model in two and three dimensions which takes into account rotational degrees of freedom is discussed both classically and quantum mechanically. The typical chaotic features found in this description of heavy-ion collisions are connected with the anomalous behavior of several experime...

The output error of the globoidal cam mechanism can be considered as a relevant indicator of mechanism performance, because it determines kinematic and dynamical behavior of mechanical transmission. Based on the differential geometry and the rigid body transformations, the mathematical model of surface geometry of the globoidal cam is established. Then we present the analytical expression of th...

Wind and earthquake disasters in the world often cause billions of dollars of damage to buildings, most of which is to non-engineered buildings-especially homes. Wood-frame homes use connectors which exhibit partial rotational rigidity at the member ends, making analytical solutions difficult. This is due to the lack of information about the complex behavior of the connections used in this type...
