	Balloon Dilation Treatment of Phimosis in Boys
		The balloon dilation technique for treating phimosis in boys includes a balloon catheter, an inflator, a valve clip and two curved retractors, which are all made of disposable plastics.
		Balloon dilation treatment is indicated for boy patients with a constricted preputial orifice impeding retraction of the prepuce over the glans penis and/or a history of either urinary tract infection, frequent micturition or bradyuria due to phimosis before the age of three years.
		Dilation of the prepuce should be terminated if the balloon waist disappears or when the balloon diameter is 3-5mm greater than that of glans penis.

	Dilation
		Dilational lineaments are part of a larger array of Europan lineae which crisscross the satellite, discovered by the Voyager spacecraft (Smith et al., 1979; Lucchitta and Soderblom, 1982), and viewed at higher resolution by the Galileo spacecraft (Belton et al., 1996; Greeley et al., 1998; Greenberg et al., 1998a).
		Dilation may accompany ridge formation when ice or slush accumulates in the cracks, forcing the opposing blocks apart when daily compressive tidal stress is applied, according to Greenberg et al.
		Because external pulling counteracts tidal compression, the relative importance of the two end-member processes determines the morphology of Europan dilational lineaments, by controlling the degree of elevation, and the prominence of a central groove and of bilateral symmetry.

	Post-op Dialation
		Dilation is the process of inserting a series of vaginal stints into the vaginal cavity in order to prevent it from closing up.
		Dilating is inconvenient, it is sometimes a little painful as we graduate to the larger stints, and it always seems to be interrupting our daily (or nightly) routines.
		Dilation is a too often neglected part of the overall sexual reassignment surgery procedure.

	Intact dilation and extraction - Wikipedia, the free encyclopedia
		Intact dilation and extraction (IDX or Intact DandX), is a surgical abortion procedure wherein an intact fetus is removed from the womb via the cervix.
		While the term "partial-birth abortion" mainly refers to the Intact dilation and extraction procedure, courts have found that legislation intended to ban so-called partial-birth abortions could be interpreted to apply to some dilation and evacuation (DandE) procedures.
		Haskell's term was a variation on "intact dilation and evacuation (intact DandE)", the term preferred by Dr. James McMahon, who developing the procedure in 1983 as an alternative to dilation and evacuation or DandE.

		Esophageal dilation is a procedure that allows your doctor to dilate, or stretch, a narrowed area of your esophagus [swallowing tube].
		After the dilation is done, you will probably be observed for a short period of time and then allowed to return to your normal activities.
		This allows the dilation to be performed gradually and decreases the risks of the procedure.

		Dilation can affect your ability to drive, read and move around in bright lights for few hours, depending on type and strength of drops used and your iris pigmentation.
		Dilation is not used to detect diabetes, just the damage to the eye from diabetes that leads to a lot of blidness, most of which is preventable if detected early.

		The mathematical definition of grayscale dilation is identical except for the way in which the set of coordinates associated with the input image is derived.

		Dilation can also be used for edge detection by taking the dilation of an image and then subtracting away the original image, thus highlighting just those new pixels at the edges of objects that were added by the dilation.

	sciforums.com - Experiment to demonstrate mutual observed time dilation
		If however you are claiming that time dilation experienced in GPS is due to SR but that reciprocity does not apply then you are clearly wrong and I challenge you to show anywhere that there is an exclusion of reciprocity in the definition of relative velocity in SR.
		However, if some muon experiment were to be succesful at demonstrating time dilation of a system that is absolutely free of all acceleration, then we would have to conclude that it is the muon's motion that is causeing the time dilation.
		In GPS the surface clock is not at the center, the referance is at the center and indeed the orbit is dilated relative to the surface velocity but not by the differance in perepheral velocity but by the ratio of gammas relative to the center of the earth or a preferred common local rest frame.

		In order to explain the lack of time dilation in quasars, the mechanism responsible must be something that precisely evolves with the quasar population in such a way as to offset the time dilation and exactly cancel it out (observationally).

	SingaporeMoms - Parenting Encyclopedia - Cervical dilation
		Cervical dilation is the dilation (widening) of the cervix during childbirth.
		In the final stages of pregnancy, the cervix may already have opened up to 1-3 cm, but during the first stage of labour, repeated uterine contractions lead to rapid further widening of the cervix to 10 cm.
		The pain experienced during dilation is similar to that of menstruation (although markedly more intense), as period pains are thought to be due to the passing of endometrium through the cervix.

		So-called time dilation in SR is a major preoccupation for physicists and students alike and stimulant for imagination.
