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.
Gynecology and obstetrics includes many disciplines, all dedicated to the health and well-being of women outside pregnancy (gynecology) or during pregnancy and childbirth (obstetrics). It is a surgical specialty, but in Usa, some gynecologists do not operate and are not delivery. In this case, they are called medical gynecologists.
