Order of the Golden Chain hospitals and convalescent homes for the sick, aged and orphaned. During World War II, the Order of the Golden Chain sold more than four million dollars of War Bonds, donated ambulances, mobile kitchens, and an airplane named "The Spirit of the Golden Chain." The United States government accorded the Order of the Golden Chain the honor of christening a Liberty ship, the "Louis L. Bamberger", in recognition of their good deeds. The Order incorporated its Charity Foundation and in 1945 in Blairstown, NJ, that Foundation established Camp Golden Chain for underprivileged children of all races, creeds and colors. Members of
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
