The hypothesis that the atmosphere may be constrained to operate at nearly maximum efficiency is examined. If atmospheric efficiency is defined as the ratio of the rate of production of kinetic energy to the rate at which solar energy reaches the top of the atmosphere, the problem becomes equivalent to finding the maximum rate at which dia-batic heating generates available potential energy (APE...

This paper analyzes Cassirer‟s account of the coordination of concepts and spatiotemporal objects. We shall see that, in contradistinction to Kantian schematism, Cassirer maintains that this coordination is not achieved by means of a third element (the schema), which albeit intellectual is nevertheless also sensible. Rather, in Cassirer‟s view, the coordination will take place through a specifi...

A gauge invariant regularisation for dealing with pure Yang-Mills theories within the exact renormalization group approach is proposed. It is based on the reg-ularisation via covariant higher derivatives and includes auxiliary Pauli-Villars fields which amounts to a spontaneously broken SU (N |N) super-gauge theory. We demonstrate perturbatively that the extended theory is ultraviolet finite in...
