A trimpot or trimmer potentiometer is a small potentiometer which is used for adjustment, tuning and calibration in circuits. When they are used as a variable resistance (wired as a rheostat) they are called preset resistors.
Gynecologists specialize in the female reproductive system, but also care for women's overall health. A gynecologist is a doctor who treats medical conditions and diseases that affect women and their reproductive organs. (Gynecologists are also trained in obstetrics-the care of women during pregnancy and childbirth, which overlaps with gynecology.) 2.
It is common that most physicians in this field of work do both gynecology and obstetrics. Usually as the Ob/Gyn physician ages he/or she will retire from the obstetric practice due to the irregular and demanding schedule of obstetrics but will continue treating patients for gynecology only.
