The occasion offered by the construction of a new branch of Naples Subway and the related geotechnical and archaeological investigations allowed recognition that the city shoreline underwent remarkable changes during the Late Holocene highstand, when coastal evolution was influenced by vertical ground movements. In particular, for three investigation sites the density and quality of data were such to permit, for the first time, the reconstruction of graphs of relative sea level change (RSLC) which, compared with curves of the coeval eustatic changes in the Tyrrhenian Sea, were transformed into data about the Late Holocene history of local tectonics. By averaging the data collected in all the different sites, the obtained curve of the tectonics suggests that the coastal strip of Naples underwent a subsidence rate of 1.3. mm/a from about 5000 BP to the XII century AD, followed by a 1. m uplift during the last eight centuries (mean rate of 1.0. mm/a). The subsidence trend is consistent with the regional tectonics, even if the mean rate was less that in other portions of the Bay of Naples graben, probably because the study area lies among the parallel, synthetic faults forming the NW margin of that depression (Magnaghi-Sebeto Fault Zone) and not on the proper hanging-wall block. The prevailing subsiding trend was probably interrupted by minor episodes of uplift not only in the last eight centuries but also during the 3rd millennium BC, likely in connection with periods in which the volcano-tectonic phenomena of the Phlegrean Fields district superimposed on the descending movements caused by the MSFZ. The three investigation sites share substantially the same tectonic behaviour in the long term, but the details of their RSLC records show also discrepancies in some centuries. If not due to errors in dating and/or in estimating palaeo-elevations, such discrepancies could be ascribed to episodes of fragmentary tectonic behaviour due, probably, to occasional reactivation of some E-W trending minor lines of the Magnaghi-Sebeto Fault Zone. © 2010 Elsevier Ltd and INQUA.

Along the Apulian Adriatic coast, in a cliff south of Trani, a succession of three units (superimposed on one another) of marine and/or paralic environments has been recognised. The lowest unit I is characterised by calcareous/siliciclastic sands (css), micritic limestones (ml), stromatolitic and characean boundstones (scb), characean calcarenites (cc). The sedimentary environment merges from shallow marine, with low energy and temporary episodes of subaerial exposure, to lagoonal with a few exchanges with the sea. The lagoonal stromatolites (scb subunit) grew during a long period of relative stability of a high sea level in tropical climate. The unit I is truncated at the top by an erosion surface on which the unit II overlies; this consists of a basal pebble lag (bpl), silicicla - stic sands (ss), calcareous sands (cs), characean boundstones (cb), brown paleosol (bp). The sedimentary environment varies from beach to lagoon with salinity variations. Although there are indications of seismic events within the subunits cs, unit II deposition took place in a context of relative stability. The unit II is referable to a sea level highstand. Unit III, trangressive on the preceding, consists of white calcareous sands (wcs), calcareous sands and calcarenites (csc), phytoclastic calcirudite and phytohermal travertine (pcpt), mixed deposits (csl, m, k, c), sands (s) and red/brown paleosols (rbp). The sedimentation of this unit was affected by synsedimentary tectonic, attested by seismites found at several heights. Also the unit III is referable to a sea level highstand. The scientific literature has so far generally attributed to the Tyrrhenian (auct.) the deposits of Trani cliff. As part of this work some datings were performed on 10 samples, using the amino acid racemization method (AAR) applied to ostracod carapaces. Four of these samples have been rejected because they have shown in laboratory recent contamination. The numerical ages indicate that the deposits of the Trani cliff are older than MIS 5. The upper part of the unit I has been dated to 355±85 ka BP, thus allowing to assign the lowest stromatolitic subunit (scb) at the MIS 11 peak and the top of the unit I at the MIS 11-MIS 10 interval. The base of the unit II has been dated to 333±118 ka BP, thus attributing the erosion surface that bounds the units I and II to the MIS 10 lowstand and the lower part of the unit II to MIS 9.3. The upper part of the unit II has been dated to 234±35 ka BP, while three other numerical ages come from unit III: 303±35, 267±51, 247±61 ka BP. At present, the numerical ages cannot distinguish the sedimentation ages of units II and III, which are both related to the MIS 9.3- MIS 7.1 time range. However, the position of the units, superimposed one another, and their respective age, allows us to recognise a subsidence phase between MIS 11 and MIS 7, followed by an uplift phase between the MIS 7 and the present day, which led the deposits in their current position. This tectonic pattern is not in full agreement with what is described in the literature for the Apulian foreland. © Società Geologica Italiana, Roma 2013.

The American designation T/P92 used for tubes and pipe, respectively, indicates a creep enhanced ferritic steel (CSEF) that was originally developed by Nippon Steel under the name NF616 as an alternative to Grade 91. This grade is also referred to as Grade 92 and is available under the European designation XIOCrWMoVNb9-2 (included in EN 10216-2) as well as American designations such as ASTM A213 T92, A335 P92, A387 Gr92, A182 F92 and A369 FP92. In general, welding of P92 and similar CSEF grades is considered rather straightforward, provided that the correct welding procedures, filler metal and heating cycles are applied by welder with suitable skills. A review of published data on requirements to be considered when developing welding procedures for Grade 92 is presented in Sections 1 and 2 and summarised in Table 2. With regard to filler metals, commercially available matching grades are tabulated in Table 1. In addition, welding parameter ranges, extracted from various welding procedure specifications (WPSs) applied in industry for Grade 92 and similar, are summarised in Table 3.

The Calabrian coast is the landscape element of greater economic importance as it is one of the few voices of regional GDP continues to grow. The coastal area of Santa Maria di Tropea (VV) is the landscape element is based on the tourism area which receives 20[%] of tourists of the Calabria region and more than 50[%] of the foreign ones. The multi-temporal analysis of dynamic elements using GIS (beach, river network and land use) and non-convertible (geology, morphology) is a tool for investigation of the evolution of the landscape highlighting critical issues and relations of cause and effect. The elements of the coastal landscape were analyzed using GIS through the use of integrated and comprehensive bibliographic data and relating to the interpretation of satellite and aerial images (Calabria Region, regional mapping and Geographic Information System) from 1954 to 1998 and 1998 to 2008. The area of the study covers 5 km2 and is characterized by a substrate plutonic (tonalite) covered by a sedimentary sequence I-Pliocene deposits of terrace sandy-conglomeratic. The area is characterized by terraced areas to a torrential river network and a coastline with two pocket beaches and Santa Maria Grotticelle. The urban areas in the period 1954-1998 increased from 0,044 km2 to 1.2 km2 obliterating the dune system and partly the backshore. Between 1998-2008 there was an increase in the area of Santa Maria of about 0.2 km2 (total 1.4 km2). This increase in urban areas is associated with a retreat of the shoreline. Between 1998 and 1958 in the area of Santa Maria there is a loss of backshore equal to 5,998 m2 and 12,204 m2 between 2008 and 1998. In Grotticelle there is instead a small increase of 635 m2. The total length of the river network in 1958 stood at 9.2 km which decreases to 4.8 km due to heavy urbanization. The growing urbanization of the area of Santa Maria di Tropea is one of the main causes of the decrease in the emerged beach and especially the reduction of the power systems of the coastal system. This analysis allows us to highlight how land use planning aimed at the growth of tourism has triggered and/or amplified erosion processes, determining conditions of landslide risk and coastal environment and the loss of the economic value of the resource landscape. In this context there is a clear need for structural which must be associated with actions of planning, restoring the equilibrium of the coastal system and management of the resource landscape through choices of sustainable tourism development is also necessary. © Società Geologica Italiana, Roma 2015.

About four years ago, the Lazio chapter of the Italian Society of Environmental Geology (SIGEA) launched a survey of Urban Geosites within the municipality of Rome, employing specially-designed data sheets to be compiled primarily by the Society's members. The goal of the survey was to define a certain number of sites, areas or elements affected by urban development, where it was possible to establish geological value worthy of conservation. The project was devised in order to highlight the fact that geological studies in urban areas are adversely affected by a number of circumstances, first and foremost the scarcity of geological outcrops - destroyed, excavated or otherwise hidden beneath the "continuum" of asphalt and cement. It was thus decided to create a record of the outcrops intentionally left within urban areas, as well as those presumably destined to disappear and those that have already disappeared but for which we possess historical/photographic documentation. © Società Geologica Italiana, Roma 2015.

Detection of non compliance with hygienic requirements is the major issue of a recent judgement of the Court of Justice of the European Union (CJEU). As long as the hygiene package addresses some obligation under condition as where necessary, if appropriate and similar, it is up to the official control to identify whether a infraction is at stake. In October 2011, the CJEU established the need of a correlation between the requirements regulated in the Annex of Regulation (EC) No. 852/2004 and Article 4(2) of the same regulation on one side, and the context of those provisions, on the other. By this way, the Court affirms that food business operators have to put adopt, implement and maintain a permanent procedure or procedures based on the Hazard Analysis Critical Control Point (HACCP) principles. Since hygienic requirements must be interpreted so as not to deprive Article 5 of the Reg. (EC) No. 852/2004 of effectiveness, it follows that when competent Authorities seemingly do not reckon actual contamination, one cannot conclude that a breach to law occurred on the basis of the finding that a potential purchaser could conceivably have touched foodstuff by hand or sneezed on it only. In such a case, competent Authority should take into consideration measures taken by those operators under Article 5 of the regulation in order to prevent, eliminate or reduce to acceptable levels the hazard inherent to the food process. This statement is of crucial importance since it requires a stronger effort by the official control in detecting violations to food law and gives room to a number of perspective shortcomings between EU food hygiene law and the Italian criminal food law. © C. Biglia and D. Pisanello, 2013.
