This paper analyzes inequality systems with an arbitrary number of proper lower semicontinuous convex
constraint functions and a closed convex constraint subset of a locally convex topological vector space.
More in detail, starting from well-known results on linear systems (with…

Background: Male alcohol consumption is one of the accepted risk factors for intimate partner violence. The aim of this study is to assess the magnitude of the association between male alcohol consumption and intimate partner violence against women and the…

Although radix 10 based arithmetic has been gaining renewed importance over the last few years, decimal systems are not efficient enough and techniques are still under development. In this paper, an improvement of the CORDIC (coordinate rotation digital computer) method…

In this work we study the effect of the glass substrate on the efficiencies of the different orders that propagate inside a transmission sinusoidal diffraction grating. Holographic optical elements are usually recorded on a photosensitive medium deposited on to a…

The idea that technology can transfer a person to a different environment without any physical movement and create the illusion of interaction with the artificial environment is not new. Scientists and engineers have been dedicating their efforts to its progressive…

This paper analyzes the effect on the optimal value of a given linear semi-infinite programming problem of the kind of
perturbations which more frequently arise in practical applications: those which affect the objective function and the right-hand-side coefficients of the…

Activated carbon/polyaniline composites have been prepared using different electrochemical methods: single-step potentiostatic polymerization, multiple-step potentiostatic polymerization, and potentiodynamic polymerization with the anodic potential limits being fixed at either 0.75 or 1 V (vs Ag/AgCl). The prepared composite samples were characterized…

A review of all known descriptions of immature stages of the species of the genera Scaeva Fabricius, 1805, Ischiodon Sack, 1913 and Simosyrphus Bigot, 1882 is presented using SEM illustrations. The third instar larval and/or pupal morphology of Scaeva dignota…

Hypontremia defined as a serum concentration below 135 mmol/L (1 mmol/L - 1mEq/L). The aim of the present study was to analyze the effects of half-ironman triathlon on serum sodium concentration in Brazilian triathletes. Significant changes after triathlon completion was…

Background: Most research on gender bias has been carried out in hospitals and focuses mainly on severe diseases. Consequently, little is known about gender bias in relation to other illnesses and healthcare settings.
Aim: To explore the existence of gender…
