The organic electrolyte cell that is suitable for application of direct current backup of pulse load with load width on the order of milliseconds and has higher backup capability than the conventional design is achieved by setting the product R\xb7C of an impedance R at 1 kHz and a capacity C is in a range from 0. Also provided is a method of treating cancer, restenosis, atherosclerosis, endometriosis, and psoriasis and a pharmaceutical composition that comprises a compound that is an irreversible inhibitor of tyrosine kinases. The photosensitizer containing formulations and compositions of the invention comprise one or more block copolymers. The treating and measuring are performed until the measuring indicates that the desired reflectivity has been achieved. The response can indicate that the calendarable event has been added to a calendar or can request further information about the calendarable event.
