             abstract = "Observational data from solar radio emissions have presented 
                         chaotic signatures. Isliker and Benz (1994), using data from 
                         several solar events involving radio emissions from the 
                         spectometer IKARUS at Zurich, found that during solar radio bursts 
                         the temporal time series exhibit intermittent patterns. Kurths and 
                         Schwarz (1994) showed that solar radio bursts detected at the 
                         Metsahovi Radio Research Station (Helsinki) exhibit transient 
                         behavior, which is characteristic of chaotic systems. Nonlinear 
                         wave-wave interactions can be a source of radio emissions. 
                         Theoretical studies of generation of solar and planetary radio 
                         emissions have been carried out. Chian et al. (2000) studied a 
                         model for the nonlinear 3-wave interactions involving Langmuir, 
                         whistler and Alfv{\'e}n waves, and its evolution from orderly to 
                         chaotic behaviors. In Chian et al. (2002), two types of 
                         intermittency were recognized in the numerical simulation of space 
                         plasma emissions. Miranda et al. (2005) investigated the 
                         phenomenon of intermittency for a nonlinear model of 4-wave 
                         interactions. In this work we study the temporal dynamics of a 
                         nonlinear model of 3-wave interactions involving one pump wave and 
                         two damped waves with different damping rates in space plasmas. 
                         First, we construct a bifurcation diagram by choosing the damping 
                         rate of the second induced wave as our control parameter, and 
                         keeping all other system parameters constant. Then, we show the 
                         occurrence of two different types of intermittency in the 
                         numerical time series. The results presented in this study can 
                         improve our understanding of the intermittency frequently observed 
                         in chaotic time series from solar and planetary radio emissions.",
