Thirty Years of Innocence

Thirty years of ISFETOLOGY

This paper describes the development of ISFETs in an historical setting, but is not limited to that. Based on the development regarding the theory, the technology, the instrumentation and the experience with many specific applications, also future projects are defined, such as concerning cell acidification, REFET biasing and a complete new range of FET sensors based on local pressure induction ...

Thirty years later

Elliptical galaxies are modelled as homeoidally striated Jacobi ellipsoids (Caimmi & Marmo 2005) where the peculiar velocity distribution is anisotropic, or equivalently as their adjoints configurations i.e. classical Jacobi ellipsoids of equal mass and axes, in real or imaginary rotation (Caimmi 2006). Reasons for the coincidence of bifurcation points from axisymmetric to triaxial configuratio...

Thirty Years of Numerical Taxonomy

-In this history of numerical taxonomy since the publication in 1963of Sokal and Sneath's Principles of Numerical Taxonomy, I include reminiscences of the reactions of biologists in Britain and elsewhere. Much of the original program has proved sound. The debate on phenetic and phylogenetic classifications has been valuable, although the logical and theoretical aspects of phenetics have been gr...

Thirty Years of Saying NO

The historical demonstration by Furchgott and Zawadzki that removal of the endothelium abrogates the in vitro vasodilator effect of acetylcholine has led to the identification 30 years ago of nitric oxide (NO) as a major endogenous local regulator of vascular tone. When the ability of endothelial cells to produce NO is blunted, the ensuing vascular dysfunction sets the stage for the occurrence ...
