from the engine to the tires. With CVT, diameters of the areas where the two pulleys meet the belt can be infinitely varied (Figure 1). Each pulley consists of two conical plates facing each other, which by moving closer or further apart, changes the diameter of the area meeting the belt (Figure 2).
What is Ureteropelvic Junction Stenosis (UPJ Stenosis)? It is one of the most common benign diseases causing renal pelvis dilatation. It mosttly occurs in children and is mainly congenital (from birth). Ureteropelvic junction (UPJ) is the point where the ureter meets the renal pelvis. Renal pelvis is like a 'sink' collecting urine produced by the kidney, while UPJ is the 'sink-trap' (siphon) through which the urine has to pass so that it will end to the bladder through the ureter.
The mesovarium is a fold of peritoneum that holds the ovary in place. The suspensory ligament anchors the upper region of the ovary to the pelvic wall. Attached to this ligament are blood vessels and nerves, which enter the ovary at the hilus. The ovarian ligament anchors the lower end of the ovary to the uterus. The following two tissues cover the outside of the ovary: The germinal epithelium is an outer layer of simple epithelium.
