Polychlorinated Biphenyls in Sediments from Sicilian Coastal Area (Scoglitti) using Automated Soxhlet,GC-MS,and Principal Component Analysis

A methodology for the PAHs and PCBs congener determination in sediment samples has been revised. We determined the distributions of PAHs and PCBs in the superficial sediments of the Scoglitti (Italy) coastal area to provide data for comparison with other marine systems and to hypothesize the sources. Extraction yield, for PCB, was never less than 60% in most cases, while for PAHs, utilizing perdeuterated surrogate standard (benz[a]anthracene-d₁₂ and anthracene-d₁₀) was never less than 72%. The total concentration of the 16 PAHs investigated, expressed as the sum of concentrations, ∑PAHs, varied from 1–5087 μg/kg of dry matrix, while the ∑ PCBs ranged from detection limit to 36 μg/kg of dry matrix. Linear relationships were found between PAHs concentration and organic matter percentages (R² = 0.60) and water content and organic matter percentages (R² = 0.87). Isomeric ratios were used for discriminating between pyrolitic and petroleum origin. The principal component analysis (PCA) has been conduced to discriminate the different sampling sites in internal or external harbor area.     

Education,practice and professionalism: a comparative history of the development of urban and regional planning in Italy and Australia

This paper outlines the historical relationship between planning legislation, planning practice and planning education in Italy and Australia by identifying the positive and negative roles of institutional influences and the emergence of professional planning communities. The key findings revolve around the gap between plan preparation and plan implementation, and the role of institutions and professional communities in resisting political interference and maintaining a technocratic imperative within planning systems. While the exertion of professional power can be seen to achieve positive planning and development outcomes, it is often at the expense of the democratic traditions that have come to characterize postmodern planning systems.     

Geography,market potential and industrialization in Italy 1871–2001

This paper deals with industrialization in Italy between 1871 and 2001, and is based on data on the labour force per province (NUTS 3) from population censuses. Particular attention is devoted to long‐term trends and North–South disparities. After the analysis of the geographic spread of industry and its changes, we test the role of access to markets on the distribution of the labour force in manufacturing. The results show that access to markets played a main role in Italian industrialization and in the evolution of inequalities among Northern and Southern regions.     

An Unconventional Low-Cost Museum

Valentina Croci describes how a diminutive museum dedicated to the feminine arts in Salerno, southern Italy, provides an intimate experience for visitors: its modest interior being enriched by an interface of information panels and interactive installations designed by Id-Lab in Milan.

A Simulation Study of CO2 Sequestration in the Arno River Plain (Tuscany,Italy)

We present a geochemical model for the sequestration of anthropogenic CO₂ (from hypothetical hydrocarbon-based H₂ production) consequent to the theoretical injection of gas beneath the River Arno plain, near the city of Pisa, Italy. The potential reservoirs for gas disposal are of two different types: dolostones or sandstones. The model predicts the sandstones to be the best reservoirs because CO₂ sequestration in these rocks can occur via the deposition of solid carbonates. On the contrary, the injection of gas into the dolostone could generate gas accumulation and high gas pressures (50–100 atm) that could possibly promote rock fracturing and gas leakage in these shallow (500–1000 m depth) reservoirs. The best sites for gas disposal are therefore located west of the town of Pisa, along the coastal plain.     

Tradable white certificate schemes: fundamental concepts

A number of European countries have introduced market-based instruments to encourage investment in energy efficiency improvement and achieve national energy savings targets. Some of these schemes are based on quantified energy savings obligations imposed on energy distributors or suppliers, coupled with a certification of the energy savings (via white certificates), and a possibility to trade certificates. The paper describes the concept and the main elements of a tradable white certificate scheme, where appropriate giving examples from existing schemes in Europe. It discusses design and operational features that are key to achieve the overall savings targets, such as delineation of the scheme in terms of obliged parties, eligible projects and technologies, institutional structure, and processes to support the scheme, such as measurement and verification. Finally, the paper looks at a number of open issues, most importantly the possibility of creating a voluntary market for white certificates via integration into the carbon market.

Tanaro Bridge: Dynamic Tests on a Couple of Spans

The Tanaro Bridge, an 18-span 225-m long bridge on the Tanaro River in northwestern Italy, presented the following elements of interest: (1) the barrel divided into adjacent arches; and (2) transverse tie bars and internal spandrels connecting the three parts of the barrels. Its demolition, in 2003, gave the opportunity of performing dynamic tests on a couple of spans at two stages of demolition: (1) fill removed; and (2) fill and internal spandrels removed. Without the uncertain contribution of the fill, some features of the mechanical response of masonry bridges are discussed and the efficiency of tie bars and internal spandrels is addressed. The data provided can be useful for safety assessment procedures.
