Due to the progressive lowering of the age of peak performance among swimmers, it became important to better understand the factors influencing performance in prepuberal boys and girls. Aim of this study is to compare two different racial/ethnic groups of…

Recording noise gratings with single-beam exposures in bleached silver halide emulsions is used as a holographic spectroscopy technique in order to analyse and optimize photochemical processing. In particular, rehalogenating type bleachings are analysed by measuring the transmittance through the recorded…

We propose a two step method which enables us to obtain transmission Holographic Optical Elements of high diffraction efficiency as well as a good signal-to-noise relation. By means of a device using partially coherent light, a master Holographic Optical Element…

Nanostructured cobalt oxide (Co3O4) electrodes were prepared by two different methods. The first one involved the synthesis of Co3O4 nanoparticles through a nanocasting route using commercial silica gel as a sacrificial template, and in the second one, the Co3O4 electrodes…

Theodore Motzkin proved, in 1936, that any polyhedral convex set can be expressed as the (Minkowski) sum of a polytope and a polyhedral convex cone. This paper provides five characterizations of the larger class of closed convex sets in finite…

A quantitative study of the impacts on library budgets, expenditures on books vs serials, and overall collection development of different types of libraries, resulting from publishers' practice of marketing "the big deal", i.e. the bundling of journals and e-journals in…

This paper focuses on prediction and prevention of seismic risk through a system for decision making.
Data Warehousing and OLAP operations are applied, together with, data mining tools like association rules, decision trees and clustering to predict aspects such as…

Four questions dominate normative contemporary constitutional theroy: What is the purpose of a constitution? What makes a constitution legitimate? What kinds of arguments are legitimate within the process of constitutional interpretation? What can make judicial review of legislation legitimate in…

Proposes some fundamental differences in assumptions between old and new paradigms and argues that the preoccupation with growth
characteristic of a materialist view is what has
brought about our current crisis.
