Multilayer feed-forward neural networks (MLF) represent the type of ANNs most widely applied to electronic tongue data. Their scheme is shown in Fig. 2.17.

The ability of the trichothecenes to produce dermal toxicity is rather unusual for toxins. While only the more potent trichothecene mycotoxins have this effect, the cytotoxicity produced on contact with feed may result in lesions on the snout, muzzle, lips, and tongue of animals. Similar dermal effects have been reported in humans and in swine following topical application of T-2 toxin. T-2 toxin, DAS,... 

Snails and slugs feed on plants at night. They tear holes in foliage, fruits, and soft stems, using a rasp-like tongue. They may eat entire seedlings. As they move, snails and slugs leave a slime-like mucous trail which dries into silvery streaks. These streaks are undesirable on floral and ornamental crops and on those portions of crops to be sold for human food. 

In the early machines and for many applications today, the particulate matter to be compacted or briquetted is fed by gravity into the nip of the rollers. Feed control is performed by adjustable tongues and distribution across the width of the roller is achieved by simple, rotating devices mounted on top of the press (Figure 225). To obtain positive feed pressure and provide a more versatile means of control, screw feeders are installed for many modern applications (Figure 226) ...

Figure 290 illustrates some feeder designs that are used to obtain uniform distribution on wide rollers. Figure 290(a) is a choke-feed arrangement with tongue control. To feed the border zones of the rolls adequately the tongue is curved, thus restricting the flow of material to the center of the roll face more than toward the ends.
