On a Generalization of Alternative Rings

Canadian Journal of Mathematics, 1970
Bruck and Kleinfeld [3] proved that any alternative ring with characteristic prime to 2 must satisfy the identitywhere the associator (x,y,z) is defined by (x, y, z) = (xy)z – x(yz) and . Linearization of the identity (x2, y, z) = 2x · (x, y, z) yields for characteristic prime to 2 an equivalent identity(1)Using the right alternative law (x, y, z ...

Surface generalizations: An alternative to alternations

cogl, 2002
Since the earliest days of generative grammar, there has existed a strong tendency to consider one argument structure construction in relation to a particular rough paraphrase. Initially this was a result of the emphasis on transformations that derived one pattern from another.

A Generalization of Commutative and Alternative Rings

Canadian Journal of Mathematics, 1970
In [3] Schafer has defined generalized standard rings as rings satisfying the identities(1)(2)(3)and observed that these identities imply (y,y, (x, z)) = 0 and if the characteristic is not three, (x, y, x2) = 0. Schafer determined the structure of simple, finite-dimensional generalized standard algebras of characteristic not two or three by showing ...

The Generic Alternative in Schizophrenia

CNS Drugs, 2004
Pharmacological treatment of schizophrenia often requires careful dosage titration to achieve satisfactory symptom control whilst minimising the risk of adverse effects. Relapses requiring hospitalisation are an important potential source of additional cost for the health service and any inadequate symptom control increases the indirect costs of ...

Permutation generators of alternating groups

1990
The problem of generation of permutations from small ones is especially important from a cryptographic point of view. This work explores the case This work addresses the design of cryptographic systems using elementary permutations, also called modules. These modules have a simple structure and are based on internal smaller permutations. Two cases have

An Alternative Way to Generalize the Pentagon

Journal of Combinatorial Designs, 2012
AbstractWe introduce the concept of a pentagonal geometry as a generalization of the pentagon and the Desargues configuration, in the same vein that the generalized polygons share the fundamental properties of ordinary polygons. In short, a pentagonal geometry is a regular partial linear space in which for all points x, the points not collinear with ...

Alternative Electricity Generation Opportunities

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2007
Abstract In this article, comparing four renewable energy sources shows 70% of the electricity generated by the four to come from geothermal with only 42% of the total installed capacity. Wind energy contributes 27% of the electricity, but has 52% of the installed capacity. Solar energy produces 2% of the electricity and tidal energy 1%.

The Alternation of Generations

1989
Publisher Summary In species with monosporic embryo-sacs the mitochondria and plastids are often concentrated in the chalazal region of the megaspore mother cell, resulting in an unequal division between the spores. This has been held to account for the promotion of the chalazal spore, but in Myosurus and some other species there is no evident ...
