The present invention provides an interactive multimedia apparatus comprising a digital musical instrument and having a plurality of control members including at least one limited state control member and one or more dynamic range state control members. The fuel management system includes a thermal reactor having an inlet port and an outlet port. To achieve this, a service node provided in the cellular network requests a suitable access bearer from the access network and the access device sets up a corresponding access channel towards the terminal device. The ram block is displaced by a ram or hydraulic cylinder in the press tool. The apparatus further includes control logic to determine whether to service an incoming probe based at least in part on a timer value. The sizes of pores and porosity can be tailored by controlling the extent of drying so that the porous bio-material with acceptable strength can be obtained.
