In secondary hypogonadism, testosterone levels are low and levels of FSH and LH are low or inappropriately normal. Any acute systemic illness can cause temporary secondary hypogonadism. Some syndromes of hypogonadism have both primary and secondary causes (mixed hypogonadism).
Function of damper winding in synchronous machine: 1.Self starting of synchronous machine: The core concept is that damper winding being short circuited carry high current, creates magnetic flux like as induction machine.Thus there is pulling in or better torque in starting.he rotor of induction machine is mostly of squirrel cage type which is short circuited thus provides high current in start up. Damper winding in synchronous machine is placed in the coil slots and short circuited.
Rebound Damping The main function of rebound damping is to control the extension of the fork or shock after it compresses over a bump--hence the term rebound. (This is also called tension, which is why you often see tens or ten on a fork rebound clicker.) Rebound damping works by dissipating the fork or shock spring's energy; once a spring is compressed, there is force--or energy--released when it springs back. If your bike's suspension was composed of only springs (no rebound damping), the wheels would continue to bounce until the energy was dissipated through friction.
