An investigation into the eco-design of energy using

products directive

CHRISTINA GOODRICK MEECH

ABSTRACT

This study reviews the eco-design of energy using products directive and

additional legislation on the way that waste electrical and electronic equipment

should be disposed of, and how this may influence the future product

design of appliances. During the investigation ‘lifecycle analysis’ and consumers’

responses to this legislation, and the industry were also reviewed.

Finally, for future product designers who work with electrical and electronic

equipment some guidelines and rules are given to consider while designing for

the environment and sustainability.

The nature of language

WILLIAM L. ABLER

ABSTRACT

Sentences share with equations properties of discrete, linear infinities;

distinct symbol types; alternation of symbol types in the signal; deepstructure

with a main verb and recursion; associative, commutative, and

distributive properties; autonomous levels of organization; paraphrase,

ellipsis, and ambiguity; powers of assertion, truth and falsity; modification

of an entire statement; and a blank proxy element. Sentences are derived

from the symmetrical equation by applying a single asymmetry transformation.

The self-regulated, autonomous nature of the symmetrical equation is

the antithesis of natural selection, which is contingent upon local conditions.

The dependence of the sentence upon the equation means that the idea of

language evolution presents numerous obstacles. For the most part, ideas

contained in this paper are adapted from the author’s book, Structure of

Matter, Structure of Mind.
