In an apparatus on a spinning preparation machine, for example, a flat card, roller card, draw frame or the like, for monitoring fiber material, having at least one rotating roller that delivers fiber material, and a monitoring arrangement device that detects undesirable accumulations of fiber material and emits an electrical signal is present. The piezoelectric film has a composition satisfying the relationship of Zr>Ti and has a polarization-electric field hysteresis loop having a Pm2Pr of 1. The hang-off gimbal assembly is movable between an open position and a closed position, such that, in the open position, the hang-off gimbal assembly is configured to receive the tubular member in the opening of the support plate and in the opening of the base plate, and in the closed position, the hang-off gimbal assembly is configured to enclose about and support the tubular member. When a query is received for execution, the query may be evaluated to determine whether portions of in-memory should be duplicated to allow multiple elements of the query to be evaluated in parallel. The generated value can be utilized as the inbound blocking factor to determine a manner in which incoming messages are to be conveyed from a network adaptor, through an adaptor interface boundary, to an operating system of the host.
