Oral feeding of 50% EtOH of Solanum xanthocarpum berry to male rats at the dose of 0.5 gm/kg body weight caused arrest of spermotagenesis. The number of spermatocytes (primary and secondary) and spermatids were significantly reduced (P<0.05 to 0.001). The total number of immature and mature leydig cells were significantly decreased (P<0.001), whereas degenerating cells were significantly increa...

We give a systematic treatment of the treatment of the classical Hannay-Berry phases for mechanical systems in terms of the holonomy of naturally constructed connections on bundles associated to th~ system. We make the costructions using symmetry and reduction and, for moving systems, we use the Cartan connection. These ideas are woven with the idea of Montgomery [1988] on the averaging of conn...

In this paper, we derive a necessary and sufficient condition on the parameters of the Hypergeomet-ric distribution for weak convergence to a Normal limit. We establish a Berry-Esseen theorem for the Hypergeometric distribution solely under this necessary and sufficient condition. We further derive a nonuniform Berry-Esseen bound where the tails of the difference between the Hypergeo-metric and...

We examine the Bloch-Peierls-Berry dynamics under a classical nonequilibrium dynamical formulation. In this formulation all coordinates in phase space formed by the position and crystal momentum space are treated on equal footing. Explicitly demonstrations of the no (naive) Liouville theorem and of the validity of Darboux theorem are given. The explicit equilibrium distribution function is obta...

By quantizing the semiclassical motion of excitons, we show that the Berry curvature can cause an energy splitting between exciton states with opposite angular momentum. This splitting is determined by the Berry curvature flux through the k-space area spanned by the relative motion of the electron-hole pair in the exciton wave function. Using the gapped two-dimensional Dirac equation as a model...

The Berry-Tabor conjecture asserts that local statistical measures of the eigenvalues j of a \generic" integrable quantum system coincide with those of a Poisson process. We prove that, in the case of a rectangle billiard with random ratio of sides, the sum N ?1=2 P jN exp(2i j) behaves for random and N large like a random walk in the complex plane with a non-Gaussian limit distribution. The ex...

We examine the spin-orbit coupling effects that appear when a wave carrying intrinsic angular momentum interacts with a medium. The Berry phase is shown to be a manifestation of the Coriolis effect in a noninertial reference frame attached to the wave. In the most general case, when both the direction of propagation and the state of the wave are varied, the phase is given by a simple expression...

We report the occurrence of Hypothenemus hampei (Ferrari) attacking Pará nuts stored in the southeast of Para state. The coffee berry borer successfully colonized and reproduced using Pará nuts as a food source. Based on this observation, the Pará nuts can be used as an alternative food source in rearing the coffee berry borer. Also, attention should be brought to need of proper storage of thes...
