Order of the Golden Chain learning disabilities and minimal brain damage. Also, through the generosity of the members, along with their families and friends, four forests of more than forty trees have been planted in Israel. For its many benevolent acts, the Order was accorded the honor of having the Sunday of Brotherhood Week in February designated as "Golden Chain Day" by the non-sectarian Chapel of the Four Chaplains at Temple University, Philadelphia. The Order portrays its ideals and principles in a solemn ceremony. Six officers, known as Jewels, exalt the ideals of womanhood in tribute to their accomplishments in the home, in history, and
Genus (mathematics) manifold of complex points). For example, the definition of elliptic curve from algebraic geometry is "connected non-singular projective curve of genus 1 with a given rational point on it". By the Riemann-Roch theorem, an irreducible plane curve of degree "d" has geometric genus where "s" is the number of singularities when properly counted. Genus can be also calculated for the graph spanned by the net of chemical interactions in nucleic acids or proteins. In particular, one may study the growth of the genus along the chain. Such a function (called the genus trace) shows the topological complexity and domain structure
