A diving regulator or underwater diving regulator is a pressure regulator that controls the pressure of breathing gas for underwater diving.The most commonly recognised application is to reduce pressurized breathing gas to ambient pressure and deliver it to the diver, but there are also other types of gas pressure regulator used for diving applications.
In this list of financial regulatory and supervisory authorities, central banks are only listed where they act as direct supervisors of individual financial firms, and competition authorities and takeover panels are not listed unless they are set up exclusively for financial services.

Regulators can be designed to control anything from gases or fluids, to light or electricity. Speed can be regulated by electronic, mechanical, or electro-mechanical means. Such instances include; Electronic regulators as used in modern railway sets where the voltage is raised or lowered to control the speed of the engine
Low-dropout (LDO) regulators operate similarly to all linear voltage regulators.The main difference between LDO and non-LDO regulators is their schematic topology.Instead of an emitter follower topology, low-dropout regulators consist of an open collector or open drain topology, where the transistor may be easily driven into saturation with the voltages available to the regulator.
In addition to the mercury, the tube is filled with argon gas at low pressure. When power is applied, if there is sufficient voltage to ionize the argon, the ionized argon gas will strike a small arc between the starting electrode and the adjacent main electrode. As the ionized argon conducts, the heat from its arc vaporizes the liquid mercury ...
Argon–argon (or 40 Ar/ 39 Ar) dating is a radiometric dating method invented to supersede potassium–argon (K/Ar) dating in accuracy. The older method required splitting samples into two for separate potassium and argon measurements, while the newer method requires only one rock fragment or mineral grain and uses a single measurement of argon isotopes.
