✦ Synopsis


There are exactly three non-trivial solid varieties of semirings, the variety of all rectangular semirings, the variety V NID of all normal, idempotent, distributive semirings, and the subvariety of V NID which is defined by the additional identity x + y y + x β‰ˆ xy + yx.  2002 Elsevier Science (USA)

A solid variety is a variety in which every identity holds as a hyperidentity, that is, we substitute not only elements for the variables but also term operations for the operational symbols. There are obvious necessary conditions for a variety of semigroups to be solid. We will show here that these

It is known that all subvarieties of MV-algebras are finitely axiomatizable. In the literature, one can find equational characterizations of certain subvarieties, such as MV -algebras. In this paper we write down equational bases for all MV-varieties n and prove a representation theorem for each sub

## Abstract An all‐solid actuator, consisting of a polyaniline (PANI) film and a solid polymer electrolyte (SPE) of poly(ethylene oxide) derivative (STO288), clearly showed a reversible displacement in an atmosphere when a voltage was applied between the PANI film and the SPE layer. The displacemen
