Preputioplasty or prepuce plasty, also known as limited dorsal slit with transverse closure, is a plastic surgical operation on the prepuce or foreskin of the penis, [1] to widen a narrow non-retractile foreskin which cannot comfortably be drawn back off the head of the penis in erection because of a constriction which has not expanded after adolescence.
Dorsal slit is now rare in Western countries as a treatment for phimosis. Standard guidelines suggest conservative approaches first and, should those fail, either circumcision or preputioplasty to both retain the foreskin and relieve the phimosis.
It is designed to make tire sizing consistent and clear. It replaces overlapping informal systems that ambiguously distinguished between sizes. For example, at least 6 different "26 inch" sizes exist (just by American notation), and "27 inch" wheels have a larger diameter than American "28 inch" (French "700C") wheels.
Modern road tires have several measurements associated with their size as specified by tire codes like 225/70R14. The first number in the code (e.g., "225") represents the nominal tire width in millimeters. This is followed by the aspect ratio (e.g.,"70"), which is the height of the sidewall expressed as a percentage of the nominal tire width.
29er rims have an interior diameter of 622 millimetres (24.5 in) [1] and the average 29″ mountain bike tire is (in ISO notation) 59-622 – corresponding to an outside diameter of about 29.15 inches (740 mm). The typical 26″ MTB tire has a rim diameter of 559 millimetres (22.0 in) and an outside tire diameter of about 26 inches (660 mm). [2]
Phimosis (both pathologic and normal childhood physiologic forms) is a risk factor for paraphimosis; [5] physiologic phimosis resolves naturally as a child matures, but it may be advisable to treat pathologic phimosis via long-term stretching or elective surgical techniques (such as preputioplasty to loosen the preputial orifice or circumcision ...
These rims are the same bead seat diameter as 700C wheels and are generally compatible with bicycle frames and tires designed for the 700C standard, however, rims designated as 29 inch are designed for wider tires than rims designated 700C, so frame clearance may be an issue. The formerly popular 27 inch (630 mm) wheel size is now rare.
Prior to 1964, tires were all made to a 90% aspect ratio. Tire size was specified as the tire width in inches and the diameter in inches – for example, 6.50-15. [29] From 1965 to the early 1970s, tires were made to an 80% aspect ratio. Tire size was again specified by width in inches and diameter in inches.
