Disclosed are compositions and methods for removing photoresist and probing ink from a substrate. A broadcast program is received and recorded on a personal video recorder on a first personal video recorder. The optical transceiver includes a memory that has thereon an optical transceiver access identifier. A weld is formed by melting the outer insulating layers of the conductors and the inner layer of the heat-shrink sleeve by heating to a temperature higher than the temperature of the environment and lower than the predetermined higher temperature, thereby making a weld that is continuous and leaktight, and of controlled thickness. Digital electronics capability is employed and facilitates provision of numerous features including: emergency shut down by anyone while permitting reset only by authorized personnel; modular construction so as to facilitate initial installation of the overall enclosure including the aforementioned service region followed subsequently by addition of the utility controller module. Also, the present invention provides a polymeric compound using the above antimicrobial monomer, a manufacturing method thereof, and a polymeric resin composition.
