This paper extends earlier work on the definition of Wannier functions for Bloch electrons in a magnetic field. Extensions to irrational as well as rational magnetic fields are defined, and their properties investigated. The results are used to give a generalisation of the Peierls effective Hamiltonian which is valid when the magnetic flux per unit cell is close to any rational number. * Addres...

In 1970 Vernon Booth was awarded the first Prize in a competition organized by Koch-Light Laboratories Ltd, Coinbrook, Bucks., U.K.. His article 'Writing a Scientific Paper' was printed first in 1971, and 10000 copies were distributed freely by Koch-Light. A Second Edition was prepared by Dr Booth and distributed privately. Copies of the First and Second Editions are no longer in print but requ...

Observations made over an 11 year period during the development and evaluation of the GnRH vaccine GonaCon use in male white-tailed deer (Odocoileus virginianus) are summarized. Sexually mature bucks at the Penn State Deer Research Center were administered a single immunization of GonaCon in July. Some males were also given a second boost immunization in September. Compared to similar aged cont...
