In solid state electronics, either pure silicon or germanium may be used as the intrinsic semiconductor which forms the starting point for fabrication. Each has four valence electrons, but germanium will at a given temperature have more free electrons and a higher conductivity.
Circumduction. In anatomy, circumduction means to move a limb in a circular manner. Circumduction is defined as the movement pattern which is a combination of flexion, extension, adduction and abduction.ircumduction (Noun). The circular (or, more precisely, conical) movement of a body part, such as a ball-and-socket joint or the eye. It consists of a combination of flexion, extension, adduction, and abduction.
Movement of the shoulder in a circular motion so that if the elbow and fingers are fully extended the subject draws a circle in the air lateral to the body. In circumduction, the arm is not lifted above parallel to the ground so that circle that is drawn is flattened on top.he joints of the shoulder are the shoulder joint (or glenohumeral joint), and the acromioclavicular joint. Another joint in the shoulder is the sternoclavicular joint that articulates with the sternum and clavicle.
