Using methods developed by W. Singer and J. P. May, we describe a systematic approach to showing that many spectral sequences, determined by a filtration on a complex whose homology has an action of operations, possess a compatible action of the same operations. As a consequence, we obtain W. Singer’s result for Steenrod operations on Serre spectral sequence and extend A. Bahri’s action of Dyer...

A spectral sequence which may be regarded as an 'Adams spectral sequence over a fixed space 2?' has been constructed by J. F. McClendon [6] and J.-P. Meyer [8]. This note describes a generalization in which there is no need for any orientability assumptions. The construction is carried out in a suitable stable category, which may be of independent interest. An application to the enumeration of ...

This study provides a detailed analysis of the existing problems with nuclear safeguards and material accounting in Russia by comparing the existing situation both to U.S. methods and to the system of controls that existed in the Soviet era. It also examines recent U.S. efforts under the Nunn-Lugar initiative to improve safeguards and the system of material accounting and control. Finally, it c...
