The University of Genoa is one of the largest universities in Italy. Located in Liguria on the Italian Riviera, the university was founded in 1481. It currently has about 40,000 students, 1,800 teaching and research staff and about 1,580 administrative staff. Wikipedia.

Catalysis Today | Year: 2014
The data reported in the literature concerning the structure, the morphology and porosity, the physicochemical properties and the surface properties of transitional aluminas are reviewed critically. Original experimental data are reported to discuss the nature and assignment of the OH stretching bands associated to surface hydroxyl groups and the nature of the surface acidity and basicity. Suggestions are made for further investigations. © 2013 Elsevier B.V. All rights reserved.

Annual Review of Fluid Mechanics | Year: 2014
The objective of this article is to review some developments in the use of adjoint equations in hydrodynamic stability theory. Adjoint-based sensitivity analysis finds both analytical and numerical applications much beyond those originally imagined. It can be used to identify optimal perturbations, pinpoint the most receptive path to break down, select the most destabilizing base-flow defect in a nominally stable configuration, and map the structural sensitivity of an oscillator. We focus on two flow cases more closely: the noise-amplifying instability of a boundary layer and the global mode occurring in the wake of a cylinder. For both cases, the clever interpretation and use of direct and adjoint modes provide key insight into the process of the transition to turbulence. Copyright © 2014 by Annual Reviews.

Chemical Reviews | Year: 2010
A scientific review informed about the characteristics of basic compounds and materials used in industrial and technological chemistry. The review emphasized on the the properties of liquid bases, the characterization, and use of solid bases. The contribution was intended to emphasize the linkage between the chemical knowledge of acid-base interactions and the engineering of chemical processes, along with their environmental impact. It also provided evidence of trends aimed at improving process safety and limiting environmental pollution when they were related to the increased use of solid basic materials.

Annual Review of Fluid Mechanics | Year: 2010
Geomorphology is concerned with the shaping of Earth's surface. A major contributing mechanism is the interaction of natural fluids with the erodible surface of Earth, which is ultimately responsible for the variety of sedimentary patterns observed in rivers, estuaries, coasts, deserts, and the deep submarine environment. This review focuses on fluvial patterns, both free and forced. Free patterns arise spontaneously from instabilities of the liquid-solid interface in the form of interfacial waves affecting either bed elevation or channel alignment: Their peculiar feature is that they express instabilities of the boundary itself rather than flow instabilities capable of destabilizing the boundary. Forced patterns arise from external hydrologic forcing affecting the boundary conditions of the system. After reviewing the formulation of the problem of morphodynamics, which turns out to have the nature of a free boundary problem, I discuss systematically the hierarchy of patterns observed in river basins at different scales.

I investigate the behavior of spin-dependent parton distribution functions in the regions of small and large momentum fractions x. I present a systematic comparison between predictions for relevant observables obtained with various models of nucleon spin structure and a recent global analysis of spin-dependent distributions, NNPDFpol1.1. Together with its unpolarized counterpart, NNPDF2.3, they form a mutually consistent set of parton distributions. Because they include most of the available experimental information, and are determined with a minimally biased methodology, these are especially suited for such a study. I show how NNPDFpol1.1 can discriminate between different theoretical models, even though NNPDF uncertainties remain large near the endpoints x→0 and x→1, due to the lack of experimental information. I discuss how our knowledge of nucleon spin structure may be improved at small x by future measurements at an Electron-Ion Collider, and at large x by recent measurements at Jefferson Lab, also in view of its 12 GeV upgrade. © 2015 The Author.
