Aerobic exercise done in an enriched environment with intellectual activity seems to improve cognitive performance associated with the aging process of humans, although the results can sometimes be contradictory. The objective of the present study was to ascertain to what…

A solid phase enzyme-linked immuno sorbent assay (ELISA), the antigen being bound to the surface of ferrous metal beads, was evaluated as either a diagnostic or a confirmative test for syphilis by comparison with the Venereal Disease Research Laboratory (VDRL)…

This paper uses dynamic general equilibrium and computational methods, inspired by the multi-sector growth model structure in Stephen Turnovsky's work, to develop a theory that unifies two of the traditional explanations of structural change: sector-biased technical change and non-homothetic preferences.…

Sex and gender differences influence the health and wellbeing of men and women. Although studies have drawn attention to observed differences between women and men across diseases, remarkably little research has been pursued to systematically investigate these underlying sex differences.…

Energy storage technologies provide an alternative solution to the problem of balancing power generation and power consumption. Redox flow cells are designed to convert and store electrical energy into chemical energy and release it in a controlled fashion when required.…

In this article we describe a novel algorithm that allows fast and continuous learning on a physical robot working in a real environment. The learning process is never stopped and new knowledge gained from robot-environment interactions can be incorporated into…

We present an analysis of a series of four consecutive Chandra high-resolution transmission gratings observations, amounting to a total of 150 ks, of the Be X-ray source HD 119682 (=1WGA J1346.5–6255), a member of the new class of γ Cas…

Characterizations of the containment of a convex set either in an arbitrary convex set or in the complement of a finite union of convex sets (i.e., the set, described by reverse-convex inequalities) are given. These characterizations provide ways of verifying…

The aim of this paper is the characterization of a carbon felt (Le Carbone
Lorraine, RVC 4002) to be used as three-dimensional electrode. A wide
group of very different techniques were used in the physical and structural
characterization of this…

We present an available and low cost technique for the production of binary-phase diffractive optical elements designed by digital methods. We produce binary-amplitude holograms making use of a high-resolution graphic device. They are used as binary masks which are copied…
