A generalization of Paramodulation is deened and shown to lead to a complete E-uniication method for arbitrary equational theories E. The method is deened in terms of transformations on systems, building upon and reening results of Gallier and Snyder.

The utility of different reality negotiation strategies among 57 persons who had traumatically acquired severe physical disabilities was examined. It was predicted that a sense of goal-directed determination ("agency"; Snyder, 1989) would predict lower depression and psychosocial impairment scores soon after injury. To meet the demands of rehabilitation and social integration, however, it was h...

We show that a matrix is a Hermitian positive semidefinite matrix whose nonzero entries have modulus 1 if and only if it similar to a direct sum of all 1s matrices and a 0 matrix via a unitary monomial similarity. In particular, the only such nonsingular matrix is the identity matrix and the only such irreducible matrix is similar to an all 1’s matrix by means of a unitary diagonal similarity. ...

In recent years, publications from this laboratory (Snyder and Lichstein, 1940; Lichstein and Snyder, 1941; Lichstein, 1941) have indicated the value of sodium azide (NaN3) as an aid in the isolation of streptococci from clinical material containing "spreaders" and other interfering gram-negative organisms. The use of blood-infusion agar containing 0.02 per cent sodium azide for the cultivation...

The present study critically reviews the synthetic unit hydrograph (SUH) methods available in hydrologic literature. The study reveals that the traditional methods of SUH derivation, e.g., Snyder, SCS, traditional methods like Snyder and TS method that does not yield satisfactory results, and their application to the practical engineering problems is tedious and combursome. On the other hand, p...

Subterranean termites in the genus Heterotermes Froggatt (Rhinotermitidae: Heterotermitinae) are pantropical wood feeders capable of causing significant structural damage. The aim of this study was to investigate soldier morphological attributes in three Puerto Rican species of Heterotermes previously identified by sequencing of two mitochondrial genes and attributed to Heterotermes tenuis (Hag...

In earlier work we constructed a class of spherically symmetric, ̄uid dynamical shock waves that satisfy the Einstein equations of general relativity. These shock waves extend the celebrated Oppenheimer-Snyder result to the case of non-zero pressure. Our shock waves are determined by a system of ordinary di€erential equations that describe the matching of a FriedmannRobertson-Walker metric (a c...
