Abstract: A liner for being cured by electromagnetic radiation having a wavelength in a curing range. The liner includes an outer portion. The outer portion includes a tube of impermeable material that is opaque to electromagnetic radiation having a wavelength in the curing range. An inner portion includes a tube of felt internally coated with an impermeable coating that is transparent to electromagnetic radiation having a wavelength in the curing range. The inner portion is inside the outer portion. A middle portion includes a tube of impregnable material between the inner and outer portions. Curable polymer that is curable by electromagnetic radiation having a wavelength in the curing range impregnates the felt and the impregnable material. Methods of manufacturing and installing the liner are also disclosed.

Abstract: A computer implemented method for tracking bulk email can include configuring, by a bulk email client, a bulk email, wherein the bulk email includes an initial email and identifies a plurality of recipients. The method can further include iteratively executing by the bulk email client after the configuring, a sub-method until either a marked email corresponding to the bulk email is prepared for each recipient in the plurality of recipients or a request to cease continuation of processing the bulk email is generated in response to user input at the bulk email client. The bulk email client displays a graphical user interface that shows a selectable interruption element that, if selected, terminates or pauses prior to completion of a current or next iteration.
