The present invention relates to a compound according to Formula : A-p, wherein A comprises at least one substantially cell-membrane impermeable pendant group; L comprises any suitable linker andor spacer group; Y comprises at least one arsenoxide or arsenoxide equivalent; p is an integer from 1 to 10; and the sum total of carbon atoms in A and L together, is greater than 6. In one case, the pump includes a housing within which two pistons coaxially reciprocate. The nozzle chamber of a nozzle needle can also be acted upon by fuel at high pressure. The information will be gathered and automatically transmitted from a hand held device such as a barcode scanner, RFID reader, and the like, to a mobile device using a wireless connection technology, such as Bluetooth\u2122 technology.
