    Abstract: This book offers a comprehensive framework of the current state of water resources in Italy and of the main stages of the evolutionary way in the last decades for achieving an integrated, sustainable and equitable water resources management. The main paradigms of water resources development are identified as: i) engineering and economic approach to water resources exploitation, ii) focus on pollution control and water-excess management, iii) a comprehensive approach toward a sustainable and equitable distribution of resources and effective risk reduction of water-related disasters. After a section devoted to the analysis of some historic stages in the legislation framework and the governance of water and soil, with particular reference to planning, design, building and operation of water systems, two sections deal with the estimation of water resources availability on national territory and estimation of water demands in municipal, agricultural, industrial, ecosystem sectors. The complex problems that the Italian society has to solve in the water field and the main challenges of a changing world are discussed in the fourth section of the volume. The book will not only be useful for water professionals, but also for citizen who like to discern the key factors which delay the recognition of water as a resource for life. The description of the problems and adopted solutions could also serve as a guideline for similar situations encountered in other countries, improving the preparation of the responsible people.

    Notes: Minimum total energy calculations are reported for π-conjugated hydrocarbons including neutral (ground, 1 1Bu, 2 1Ag) and doped (1+ and 2+) chains and rings with up to eight carbon atoms. Two models are considered; first, a semiempirical π-electron Hamiltonian that includes both electron–electron (Hubbard) and electron–lattice (Longuet-Higgins–Salem) interactions, and second, an accurate ab initio complete-active-space self-consistent-field (CASSCF) treatment that includes the π-electron correlation effects most important in determining the bond geometries. The results of the ab initio calculations can be used to estimate the phenomenological parameters entering the semiempirical Hamiltonian and thus to obtain quantitative predictions of bond geometries from the semiempirical treatment. The two models yield qualitatively the same results for the bond geometries in all states considered, and the changes in bond geometry following excitation from ground to doped or excited states find natural interpretation in terms of short-chain limiting behaviors of soliton and polaron distortions familiar for longer chains. Further, the absolute values and sensitivities of the phenomenological parameters of the semiempirical model to various fitting schemes provide an indication of the different roles played by electron–lattice and electron–electron interactions in determining the properties of these systems. While electron–lattice interactions are found to be the most important factor in determining bond geometries, particularly in the ground and doped states, electron–electron interactions play an important and subtle role in determining the bond geometries and relative energetic orderings of the excited states. © 1996 American Institute of Physics.

    Notes: Recently we proposed a new approach to deal jointly with the presence of conformational disorder and the requirements imposed by the electronic structure of conjugated polymers in solution. The description of the system is based on the one-dimensional tight binding Hamiltonian modified in such a way to account for dependence of the electronic hopping constants on the conformational degrees of freedom. We are able to treat numerically the full statistical problem resulting from such a microscopic description. Effects arising from steric repulsion and other possible sidegroup interactions can be dealt with, using an appropriate effective potential. In this paper we present a number of new results, that we have obtained using this approach. In particular, we analyze in detail the dependence of both conjugation and persistence length on temperature and on the strength of the steric potential. These and the corresponding results for the structure of the energy spectrum suggest the existence of joint electronic and conformational changes in qualitative agreement with the thermochromic effects experimentally observed.

    Notes: Results from a set of minimum energy calculations performed for the Su Schrieffer Heeger Hamiltonian for trans-polyacetylene are presented. We fix the occupation numbers of the electronic states and look for the bond geometry which minimizes the total energy. The usual nonlinear solutions (polarons, solitons) are recovered for appropriate sets of occupation numbers of the electronic states. We study the spectrum of excited states and the properties of the model in the case of arbitrary doping. The situation where the original SSH Hamiltonian is modified in such a way as to account for the intrinsic periodicity of the monomeric units of conjugated polymers without a degenerate ground state is also examined.

    Notes: Thin polymeric coating layers are often used to improve the barrier properties of packaging structures and container walls. We study how local flaws in the coating layers affect the overall permeation properties of such systems. We find that many small "holes'' in a barrier layer are much more effective in compromising the system barrier properties than a few large "holes'' with the same total area.
