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.

The author with this review has proposed the criterions of evaluation of the state of direct and indirect methodic nutrition; scientifically validate represent the state of the art of the fit tools to a correct approach to the tied up problem list to one not suitable feeding, principal among the factors of risk for the health and conditioning of non opportune styles of life. A correct feeding, able-bodied, balanced, to regulate develops a primary role for the prevention of the cardiovascular illnesses, metabolic, articular-bone, neoplastic and for the maintenance of a state of optimal health.

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. Source

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. Source
