The invention concerns a device for homogenizing, mixing andor granulating chemicals which consist of at least one component, particularly additives, by means of an extruder consisting of several housing segments, at least one worm, a nozzle arrangement and at least one cutting device. A scattering portion for scattering an incident beam of light incident on one plane of the semiconductor layer is provided on another plane or inside of the semiconductor layer. The system in this invention can intercept data packets exchanged among the computing devices and servers and also can scrutinize virtual machine computing and networking activities, and therefore, possess the capability of analyzing, logging, reporting, and permitting or denying computing and networking activities of devices in the corporate data network.
