Disability and monstrosity: further comments.

Tardive dysmentia : further comments.

The author distinguishes between the putative neuroleptic-induced disorders of tardive dysmentia and supersensitivity psychosis. The distinction is made with regard to clinical features, response to pharmacological intervention, and proposed etiologies. It is suggested that tardive dysmentia is due not to dopaminergic supersensitivity but to some other neurotoxic phenomenon associated with the ...

Professional ethics: further comments.

Downie continues the debate over professional ethics in general, and medical ethics in particular, begun by P. Sieghart (Journal of Medical Ethics 1985 Sep; 11(3): 117-122), and furthered by Downie and Sieghart (JME 1986 Jun; 12(2): 64-66) and R. Gillon (JME 1986 Jun; 12(2): 59-60). Here Downie addresses Gillon's theses that a physician has a special obligation to his patients, that this oblig...

Some Further Comments

It has recently been observed that a stochastic (in nite degree of freedom) time series with a 1=f power spectrum can exhibit a nite correlation dimension, even for arbitrarily large data sets. [A. R. Osborne and A. Provenzale, Physica D 35, 357 (1989).] I will discuss the relevance of this observation to the practical estimation of dimension from a time series, and in particular I will argue t...

Biotechnology and Green Chemistry

White biotechnology can be regarded as applied biocatalysis, with enzymes and microorganisms, aiming at industrial production of bulk and fine chemicals to food and animal feed additives. In its turn biocatalysis has many attractive features in the context of greenchemistry: mild reaction conditions (physiological pH and temperature); environmentally compatible catalysts and solvent (often wate...
