This article starts with a comment on John White’s published in 2019 the London Review of Education , 17 (3), entitled ‘The end powerful knowledge?’, and particularly point made about specialized knowledge its relation to knowledge. It is argued here that it important clarify distinction between knowledge, systematic what Young Muller mean by as, while these are related, they not equivalent. No...

We report here for the first time, in chick retina, Muller cell localization of glutamine synthetase (GS) activity by an immunohistochemical technique, in agreement with previous reports of glial localization of this enzyme in rat brain and retina. Age-dependent changes in the endogenous enzyme activity as well as cortisol-induced changes in GS activity, both in ovo and in vitro, measured bioch...

Not much is known about the weight distribution of the generalized Reed-Muller code RMq(s,m) when q > 2, s > 2 and m ≥ 2 . Even the second weight is only known for values of s being smaller than or equal to q/2. In this paper we establish the second weight for values of s being smaller than q. For s greater than (m− 1)(q − 1) we then find the first s+ 1− (m− 1)(q − 1) weights. For the case m = ...

Two new fixed polarity linear Kronecker transforms executed over GF(3) are introduced in this article. Both transforms are based on recursive equations using Kronecker products what allows to obtain simple corresponding fast transforms and very regular butterfly diagrams. The computational costs to calculate the new pair of transforms and their experimental comparison with ternary Reed-Muller t...

In this article, the new multi-polarity helix transform for ternary logic functions has been introduced. In addition, an extended dual polarity property that had been used to optimize Kronecker and quaternary Fixed-Polarity Reed-Muller (FPRM) expressions has been applied to generate efficiently the multi-polarity helix transform over GF(3). The experimental results for the transform are compare...

Reed-Muller algebraic techniques, as an alternative means in logic design, became more attractive recently, because of their compact representations of logic functions and yielding of easily testable circuits. It is claimed by some researchers that ReedMuller algebraic techniques are particularly suitable for arithmetic circuits. In fact, no practical application in this field can be found in t...
