Two Further Aspects

Some further aspects of scatter-fringe interferometry.

It is shown that an interferometer using one scatter plate and a plane mirror is well suited for testing long focus optical systems. Stability is automatically achieved in this system because of its +1 magnification. Two methods of introducing straight fringes into the field in order to examine a nearly perfect optical system, and a method of making scatter plates to give high-contrast fringe p...

Further Aspects of Sulphur Nutrition of Legumes

THE KEY to improving the native tussock grasslands of the South Island is to obtain good legume growth. In these areas, the main nutrient deficiencies which limit the growth of legumes are sulphur, phosphorus and molybdenum. Sulphur deficiencies are very widespread (Walker et al., 195.5; Lobb and Bennetts, 1958; McLeod, 1961). The manner in which a rational fertilizer programme was formulated f...

Lethal congenital contracture syndrome: further delineation and genetic aspects.

In a national morphology based study of lethal arthrogryposis between 1979 and 1992, 40 fetuses and infants with lethal congenital contracture syndrome (LCCS, McKusick 253310) were found in Finland. The incidence of LCCS in Finland was 1:19,000 births. There were 20 affected males and 20 affected females in 26 families. In 16 cases the pregnancy was terminated after the prenatal diagnosis of to...

Further Combinatorial Properties of Two Fibonacci Lattices

In an earlier paper on differential posets, two lattices Fib(r) and Z(r) were defined for each positive integer r, and were shown to have some interesting combinatorial properties. In this paper the investigation of Fib(r) and Z(r) is continued. A bijection 1Jf: Fib(r)--+ Z(r) is shown to preserve many properties of the lattices, though IJf is not an isomorphism. As a consequence we give an exp...
