    Notes: Abstract We investigate the kinematic and dynamic dynamos that result when the magnetic field is assumed to be spatially periodic on a scale twice that of the periodicity of the underlying driving velocity, the “CP flow” of Galloway and Proctor (1992). In the kinematic regime four distinct modes are possible; all appear to exhibit fast dynamo action. In the nonlinear regime mode coupling may occur and different saturated states are possible for the same parameter values.

    Notes: Abstract Purpose: Our purpose was to test whether zona pellucida (ZP) drilling using a 1.48-μm diode laser beam on bovine IVM/IVF/IVC blastocysts is effective for embryo hatching. Methods: Blastocysts produced in vitro at day 7 after IVF were divided into control and laser-drilled groups, respectively. Results: When the rates of in vitro development of bovine embryos were examined, the average cleavage rate (〉two-cell) was 82.3% and the blastocyst rate at day 7 after IVF was 32.5%. Using these blastocysts, when the laser drilling effect was investigated at 48 hr after treatment, the total hatching rate in the laser-drilled group (98.0%) was significantly higher than that in the control group (60.0%)(P 〈 0.001). Especially, the hatched rate of the laser-drilled group (68.0%) was significantly enhanced compared with that of the control group (30.0%) (P 〈 0.001). Conclusions: These results demonstrated that laser ZP drilling on bovine IVM/IVF/IVC blastocysts can significantly increase the hatching rate.
