An Historical Review of Nova Scotia Legal Literature: a select bibliography

Expressed in simplest terms Nova Scotia law, generally speaking, is an amalgamation of English common law, English statute law and the provincial statutes which evolved following the convening of the first representative government at Halifax on October 2, 1758. From the capture of Port Royal in 1710 (which by the Treaty of Utrecht in 1713 guaranteed Acadia to the British), to the establishment of an elected assembly 48 years later, law and order were maintained at first by military law and, following the appointment of Richard Philipps as governor at Annapolis Royal, by the issue of royal instructions dated June 19, 1719. When Halifax was founded in 1749 Governor Cornwallis\u27 instructions from the Lords of Trade, April 29, 1749, granted him more sweeping powers, with the result that the colonists were governed in large measure by executive acts and royal instructions until the first assembly was called nine years later

Solution of the Nuclear Shell Model by Symmetry-Dictated Truncation

The dynamical symmetries of the Fermion Dynamical Symmetry Model are used as a principle of truncation for the spherical shell model. Utilizing the usual principle of energy-dictated truncation to select a valence space, and symmetry-dictated truncation to select a collective subspace of that valence space, we are able to reduce the full shell model space to one of manageable dimensions with modern supercomputers, even for the heaviest nuclei. The resulting shell model then consists of diagonalizing an effective Hamiltonian within the restricted subspace. This theory is not confined to any symmetry limits, and represents a full solution of the original shell model if the appropriate effective interaction of the truncated space can be determined. As a first step in constructing that interaction, we present an empirical determination of its matrix elements for the collective subspace with no broken pairs in a representative set of nuclei with $130\le A \le 250$. We demonstrate that this effective interaction can be parameterized in terms of a few quantities varying slowly with particle number, and is capable of describing a broad range of low-energy observables for these nuclei. Finally we give a brief discussion of extending these methods to include a single broken collective pair.Comment: invited paper for J. Phys.
