Extracting and consolidating knowledge from past projects can help managers in selecting projects with the correct level of riskiness, while market analysis gives directions for reaching the objective of a balanced project portfolio. To this extent, the chapter discusses strategic importance of project selection and the role of risks and uncertainties in project portfolio management and presents some fundamental and innovative frameworks and project selection methodologies for balancing risks.

Purpose: The decisions taken today relating to urban renewal interventions are rarely supported by logical and operational methodologies capable of effectively rationalising selection processes. For this purpose, it is necessary to propose and implement analysis models with the aim of promoting the sustainable development of the territory. The purpose of this paper is to define a model for the optimal allocation of scarce resources.

We axiomatize, in the multidimensional case, a social evaluation function that can accommodate a natural Pigou–Dalton principle and correlation increasing majorization. This is performed by building upon a simple class of inframodular functions proposed by Müller and Scarsini under risk.

The development of an electrochemical cell based on poly(vinyl alcohol) (PVA) hydrogel as polymer electrolyte for electrochemical impedance spectroscopy analysis (EIS) is discussed. PVA hydrogel is prepared with different cycles of freeze/thawing (F/T) employing distillated and mineral water as solutions. The PVA-disks obtained are compared for their conductivities in order to employ it in an appropriate cell for diagnostic purposes, reducing the invasiveness of the analysis on the sample.
