#regulator

• Activator — A substance, device, or structural factor that initiates, accelerates, or intensifies a chemical reaction, an industrial process, or a biological function; (as an adjective) that induces or stimulates a latent activity. In genetics, it represents a regulatory protein that increases the transcription rate of a specific gene.
• Aqualung — An autonomous underwater breathing apparatus used by divers, composed of one or more compressed air cylinders and a regulator that delivers gas at ambient pressure; a technical neologism partially adapted from the commercial trademark Aqualung. This structural device revolutionized underwater exploration, allowing complete mobility without rigid connections to the surface.
• Airport — Belonging to an airport, or relating to the activities, services, fees, or specific infrastructure of an airport. This term describes logistical, administrative, commercial, or security elements that directly serve the optimal operation of an air transport hub.
• Anemostat — A terminal device or component mounted at the end of a ventilation or air conditioning duct, structurally designed to distribute, direct, and regulate the airflow introduced into or extracted from a room. It functions by uniformly dispersing the air current to prevent draft formation and ensure optimal thermal comfort without noise.
• Anti-imago agent — A chemical substance, hormonal factor, or biological treatment that blocks, inhibits, or disrupts the transformation of a nymph or pupa into an imago (the fully developed adult stage of an insect). In a structural sense, this mechanism halts the final metamorphosis, preventing the reproduction of harmful insects and acting as a precision ecological insecticide.
• Harmonizable — Capable of being harmonized; able to be brought into agreement, aligned, or adapted to form a coherent, balanced whole free of internal contradictions. In legal or administrative contexts, it describes standards or systems with the necessary flexibility to be unified.
• Autotransformer — A special type of electrical transformer possessing a single winding on a common magnetic core, structurally serving as both primary and secondary windings through intermediate taps. This electrotechnical device is used for step-by-step or fixed variation of alternating voltage, offering high efficiency, small dimensions, and material savings compared to classic transformers with two galvanically isolated windings.
