In this paper we show that any dual of the family S of planes defined by Yoshiara [6] also satisfies the same conditions. We present a new family Y (O) of extended generalized quadrangles of order (q + 1, q -1) constructed from the dual of the Yoshiara construction S(O) [6] and show that each such e

A sufficient condition for the simple connectedness is given for an infinite family of extended generalized quadrangles Y(S) of order (q + 1, q -1) constructed in [7] from a family S of planes in PG(5, q) with some conditions. Applying this, Y(S) is shown to be simply connected when S is obtained fr
A family of c . C 2 -geometries with point residues isomorphic to the dual of the Tits quadrangles. T \* 2 (O) for the regular hyperoval O can be constructed using the quadratic Veronesean.
We present a common construction for some known infinite classes of generalized quadrangles. Whether this construction yields other (unknown) generalized quadrangles is an open problem. The class of generalized quadrangles obtained this way is characterized in two different ways. On the one hand, th
## Abstract Utilizing the plasma very long chain fatty acid assay, supplemented by mutation analysis and immunofluorescence assay, we determined the number of Xβlinked adrenoleukodystrophy (XβALD) hemizygotes from the United States identified each year in the two laboratories that perform most of t
