A method of using hop acids for increasing food and energy uptake from feed by livestock is described which includes delivering the hop acids for oral ingestion to the animals by mixing the acids with livestock feed. The mesh network forms a self-healing and self-configuring network robust against individual node failures. Lower and upper screens serving as lower and upper electrodes are disposed in the passageway in the lower and upper container regions, respectively. The sense amplifier region includes a sense amplifier coupled to the digit line, a local inputoutput line, a column select circuit coupled to the sense amplifier, and a column select line. The control processor may send the digitally encoded voice data to a transmitter or to a transmitter for direct transmission to a central authority. The transistor is turned off after data is input to a node where the transistor and the capacitor are connected to each other, and data can be held for a long time even after supply of power supply voltage is stopped.
