The search for new radicals goes on. Recently R. L. Snider ([6], see page 216) introduced the following notion. Let α and β be any two radicals. A ring R will be said to be an (α : β) ring if for any ideal A of R, we have α (R/A) ≧ β (R/A).

A multitype pair formation model for a one-sex population, without separation, with given type distribution of singles, produces a distribution of pairs with the given type distribution as a marginal distribution. The pair distribution can be seen as a nonnegative symmetric matrix.

For a finite semigroup S and pseudovariety V, (Y, T) is a V-stable pair of S iff Y ⊆ S, T ≤ S and for any relational morphism R : S ⇝ V with V ∈ V there exists a v ∈ V such that Y ⊆ R-1(v) and T ≤ R-1( Stab (v)). X ≤ S is stable if it is generated by an [Formula: see text]-chain {ai} with aiaj = ai for j < i. Given a relation R : S ⇝ A ∈ A (where A

Pair clustering and giant pairing resonances
Physical Review C, 1985Giant pairing resonances, i.e., collective two-particle excitations built upon high-lying single-particle states, are studied in the lead region. Two-particle 0/sup +/ states (T = 1) outside the /sup 208/Pb core are found to be clustered in the nuclear surface.

The study of tilting modules has the origin in the theory of finitely generated modules over finite dimensional algebras. It was initiated by \textit{S. Brenner} and \textit{M. C. R. Butler} [Lect. Notes Math. 832, 103-169 (1980; Zbl 0446.16031)], \textit{D. Happel} and \textit{C. M. Ringel} [Trans. Am. Math. Soc.

Pair 2 learning = pair programming × pair teaching
Proceedings of the Seventeenth Western Canadian Conference on Computing Education, 2012Pair programming is a frequently cited method for retaining students and improving student learning in introductory Computer Science courses. When pair programming is employed early in the curriculum, students work together to learn to program more effectively and also enjoy the programming process more than when working alone.

To pair or not to pair: chromosome pairing and evolution
Current Opinion in Plant Biology, 1998Chromosome pairing in wild-type wheat closely resembles the process in both yeast and Drosophila. The recent characterisation of a mutant Ph1 wheat and the observation that chromosome pairing in the absence of Ph1 more closely resembles that of mammals and maize has shed light on the evolution of chromosome pairing in the cereals.

The feasibility of obtaining low-cost high-quality online reinjection fluids was fi rst explored almost 30 years ago, but regulatory conservatism delayed adoption of the technique for almost 20 years. Online treatments are now commonplace in Europe. The competitive advantages of this treatment modality compared to standard convective treatments include
