Aldosterone belongs to a class of hormones called mineral corticoids, also produced by the adrenal glands. Aldosterone helps maintain blood pressure (BP) and water and salt balance in the body by helping the kidneys retain sodium and excrete potassium.ldosterone belongs to a class of hormones called mineral corticoids, also produced by the adrenal glands.

A stepper motor is a permanent magnet or variable reluctance dc motor that has the following performance characteristics: 1. rotation in both directions, 2. precision angular incremental changes, 3. repetition of accurate motion or velocity profiles, 4. a holding torque at zero speed, and.
Stepper motors may also be used for controlling position but these will consume power even in the rest period for just locking and holding the commanded position. So, servo motors are typically used in industrial robotics as a high performance substitute to the stepper motors.
