The PII proteins are found in all three domains of life as key integrators of signals reflecting the balance of nitrogen and carbon. Genetic inactivation of PII proteins is typically associated with severe growth defects or death. However, the molecular…

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…

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…

The visual and optical anisotropies of metallic and pearlescent samples have been evaluated using a multi-gonio-spectrophotometer and by adapting a gonio-template over the instrument aperture for measuring the relative spectral reflectance factor when the sample is rotated around an axis…

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…

Real-time holographic interferometry has been used to visualize the evolution of the polarization layer during dead-end ultrafiltration of PEG-10000. Several experiments at a constant pressure of 1 bar and varying the feed concentration of PEG-10000 (5–12.5 kg/m3) have been carried…

There are few data relating to stress levels and immune function, prior to, and following acute bout of resistance exercise with varying rest intervals between sets in young resistance trained men. Therefore, the aim of this study was to determine…

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…

This paper considers the task reallocation problem, where k robots are to be extracted from a coordinated group of N robots in order to perform a new task. The interaction between the team members and the cost associated with this…
