Notes: The MDQT (molecular dynamics with quantum transitions) method of Tully is applied to the vibrational predissociation of a Van der Waals cluster containing a diatomic molecule and two rare gas atoms, I2(centered ellipsis)Ne2. The vibrational degree of freedom of the diatomic is treated quantum mechanically using DVR (discrete variable representation) while all the other degrees of freedom are treated classically. The results are in very good agreement with the experimentally measured lifetimes and product state distributions. In particular, the final vibrational state distribution of I2, which could not be satisfactorily reproduced in quasiclassical studies, is well described. Based on these results a different kinetic scheme for interpreting the vibrational predissociation in this system is proposed. In addition, this work shows that the method is very promising for the study of clusters containing more rare gas atoms. © 1998 American Institute of Physics.

Notes: Evidence in the course of experiments under controlled conditions proved that the egg and juvenile characteristics of the edible Chilean sea urchin, ‘erizo’ (Loxechinus albus) influence the cultivation efficiency. Mortalities among larvae originating from eggs with a diameter 〈110 Μm were higher than among those originating from eggs with a diameter 〉100 Μm. On the other hand, the initial size of the egg did not produce any variation in the percentage of larvae which metamorphosed. The initial size of the late metamorphosing juveniles modified early growth. A direct relationship was established between the size of the juveniles and the growth rate. In conclusion, biological aspects are determinant factors in any consideration of options available for the mass production of larvae and juveniles of this sea urchin.
