Fuse assemblies, system and kits and methods for assembling fuses include a fuse body that may be universally and interchangeably used with a plurality of different end fittings providing various fuse configurations for connection to electrical circuits. The voltage signals that may be measured include line to neutral voltages and line to line voltages. The biasing circuitry can include operational amplifiers for providing positive feedback control between the output and input of the inverters. 20% to 99% by weight of at least one ester andor one amide of acrylic acid comprising a substituted protic group; ii. Team answer data is transmitted from one of the student terminals in the team to the teacher’s terminal. An overall amount of the physiological parameter may be determined by calculating a statistical measurement of the individual sensed amounts in the area.
