The limbus is the structurally rich transitional region of tissue between the cornea on one side, and the sclera and conjunctiva on the other. This zone, among other things, contains nerves passing to the cornea, blood and lymph vasculature for oxygen and nutrient delivery and for waste, CO(2) removal and drainage of the aqueous humour. In addition, the limbus contains stem cells responsible fo...

This paper challanges the view that weak work norms in generous welfare states makes them economically unsustainable. I develop a dynamic model of family-transmitted values that has a laissez-faire equilibrium with strong work norms coexisting with a social-insurance equilibrium with weak work norms. While the former has better incentives, the latter induces more intergenerational occupational ...

Method The conjunctival flap is prepared and reflected over the cornea by the method described by Scheie (I958) and the limbal area is exposed. With the blade of a scalpel, held perpendicularly to the limbal plane, a cut 3 mm. long is made in the limbal tissue (Fig. i a, b) concentric to the limbus more than half the depth of the sclera. At either end, two cuts I *5 mm. long are made perpendicu...
