Cataracts are cloudy areas that develop within the eye lens. A healthy lens is clear like a camera's, and light has no problem passing through it to the retina at the back where images are processed. When you have a cataract, the light can't get through as easily and, as a result, you can't see as well. Cataracts often form slowly, and they don't cause symptoms like pain, redness, or tearing in the eye. Some stay small and don't affect your eyesight.
A composite flight plan is actually two flight plans-one VFR and one IFR. What makes it composite is that you will transition from one to the other at some specified point during your flight.
One of Talen's long-term projects is the covered fuselage in his workshop of a 1928 Stearman C3B, a plane used to deliver U. Factor C3f is a spasmogenic fragment released from C3b by factors I and H: the heptadeca-peptide C3f was synthesized and characterized. The SEM and XRD analysis were performed on the samples denoted as C, C1b, C2b and C3b.
