Spray-dried aqueous extract from citrus by-product ("pastazzo", ExO) was studied to evaluate the polyphenols content, the antioxidant properties and the inhibition of metalloproteinases over-expressed in dysmetabolic disease. During shelf life studies, ExO changes polyphenols content and decreases the antioxidant properties. Furthermore, Citrus flavonoids are unstable in gastric environment and ExO showed an incomplete invitro dissolution rate in simulated biological fluids, probably due to their low solubility. For these reasons, formulation studies have been performed to develop spray-dried gastroresistant microsystems for oral administration. Our studies revealed that all the prepared gastroresistant microsystems preserved the polyphenols content, prolonged the shelf-life and the antioxidant efficiency of ExO and maintaining its inhibitory effects on metalloproteinases. © 2015 Elsevier Ltd.

According to a widespread view, a complete explanatory reduction of all aspects of the human mind to the electro-chemical functioning of the brain is at hand and will certainly produce vast and positive cultural, political and social consequences. However, notwithstanding the astonishing advances generated by the neurosciences in recent years for our understanding of the mechanisms and functions of the brain, the application of these findings to the specific but crucial issue of human agency can be considered a "pre-paradigmatic science" (in Thomas Kuhn's sense). This implies that the situation is, at the same time, intellectually stimulating and methodologically confused. More specifically-because of the lack of a solid, unitary and coherent methodological framework as to how to connect neurophysiology and agency-it frequently happens that tentative approaches, bold but very preliminary claims and even clearly flawed interpretations of experimental data are taken for granted. In this article some examples of such conceptual confusions and intellectual hubris will be presented, which derive from the most recent literature at the intersection between neurosciences, on the one hand, and philosophy, politics and social sciences, on the other hand. It will also be argued that, in some of these cases, hasty and over-ambitious conclusions may produce negative social and political consequences. The general upshot will be that very much has still to be clarified as to what and how neurosciences can tell us about human agency and that, in the meantime, intellectual and methodological caution is to be recommended. © 2009 Springer Science+Business Media B.V.

The methodology of damage detection through the observation of modal properties envisages continuous monitoring and belongs to the category of non-destructive methods. This work proposes a simple analysis to localize the damage inside a motorcycle component. For linear behaviour of the system under investigation, this methodology is focused on deviation of dynamical parameters (eingevalues and eigenvectors) due to the presence of damage (single o double) inside the component. Choosing a motorcycle carter is due to his particular complexity and to his location, during normal use it is working under high stress levels and little or large accidental hits could, if neglected, carry to an alteration of delicate equilibrium of motorcycle. The first step is to validate of Finite Element model and to simulate different single positions of damage. The second step was to introduce a damage in two different positions at the same time.

We consider the system of partial differential equations associated with the mathematical model for debris flows proposed by E.B. Pitman and L. Le (Phil. Trans. R. Soc. A, 363, 1573-1601, 2005) and analyze the problem of the hyperbolicity of the model. © 2010 American Institute of Physics.

We present a variational formulation of the steady Boltzmann Transport Equation (BTE), which is considered the reference model for charge transport in semiconductors. We take into account the interactions of the electrons with optical phonons and acoustic phonons, considering the general case in which the scattering processes with acoustic phonons are inelastic. We will show that, by introducing a suitable functional, it is possible to compute an approximate expression for carrier mobility in silicon. © 2011 American Institute of Physics.

A hydrodynamical model for simulating charge transport in graphene nano-ribbons is formulated by using of the maximum entropy principle (hereafter MEP). Both electrons in the conduction band and holes in the valance bands are considered and it is assumed a linear dispersion relation for the energy bands around the equivalent Dirac points. The closure relations do not contain any fitting parameters except the ones already present in the kinetic description. © 2013 AIP Publishing LLC.

It is known that speed bumps are devices capable of reducing the speed of vehicles (traffic calmingmeasures). Bumps arranged in sequence are capable of inducing a speed regime almost constant along the road sections in which they are installed. However, the impact of vehicles on the bumps generates noise that is annoying to residents. Many studies in the literature have estimated the production of noise due to the transit of vehicles over isolated speed bumps. Less investigated, however, is the phenomenon of the noise production on the speed bumps arranged in a sequence. In this paper, the authors analyze the effects of speed bumps arranged in a sequence on the production of noise. In order to do this, two urban road sections are selected with several speed bumps placed sequentially. The survey was carried out experimentally using three vehicles (a low-powered car, a high-powered car and a motorcycle). The authors, using sound level meters data, assessed the sound levels produced by these vehicles, considering the conditionings on the dynamics of motion induced by the sequence of bumps. © 2015 Institute of Noise Control Engineering.
