1 Tranurethral resection of the prostate (TURP) is the most commonly used surgical treatment for BPH. 2  A small instrument is inserted through your urethra into the prostate. 3  The prostate is then removed piece by piece. 4  This procedure usually requires a hospital stay.
Next is precession, or wobble. This cycle occurs every 26,000 years. This gyroscopic wobble of the earths axis is driven by tidal forces which are influenced by our sun and moon. The Earth is actually not perfectly round so the gravitational pull tugs the axis over time creating the wobble cycle. Now there's a technical term for you.
This mysterious effect is precession. In the general case, precession works like this: If you have a spinning gyroscope and you try to rotate its spin axis, the gyroscope will instead try to rotate about an axis at right angles to your force axis, like this:In figure 1, the gyroscope is spinning on its axis.In figure 2, a force is applied to try to rotate the spin axis. In figure 3, the gyroscope is reacting to the input force along an axis perpendicular to the input force.hey can balance on string or a finger; they can resist motion about the spin axis in very odd ways; but the most interesting effect is called precession. This is the gravity-defying part of a gyroscope.
