             abstract = "In one of our previous articles we have considered the role of a 
                         time dependent magnetic ellipticity on the pulsars' braking 
                         indices and on the putative gravitational waves these objects can 
                         emit. Since only nine of more than 2000 known pulsars have 
                         accurately measured braking indices, it is of interest to extend 
                         this study to all known pulsars, in particular as regards 
                         gravitational wave generation. To do so, as shown in our previous 
                         article, we need to know some pulsars' observable quantities such 
                         as: periods and their time derivatives, and estimated distances to 
                         the Earth. Moreover, we also need to know the pulsars' masses and 
                         radii, for which we are adopting current fiducial values. Our 
                         results show that the gravitational wave amplitude is at best h 
                         similar to 10(-28). This leads to a pessimistic prospect for the 
                         detection of gravitational waves generated by these pulsars, even 
                         for Advanced LIGO and Advanced Virgo, and the planned Einstein 
                         Telescope, if the ellipticity has a magnetic origin.",
