    Notes: Summary The effect of infection with a retrovirus carryingv-raf/v-myc oncogenes (J2 virus) on the in vitro proliferation of human large granular lymphocytes (LGL) was investigated. LGL infected with J2 virus (J2LGL), unlike uninfected cells, grew with a proliferation peak eight days after infection. Such cells retained the morphology and functional properties typical of LGL. Furthermore, 5% of J2LGL produced virus the day after infection, whereas non-virus production was detectable five days later. These data indicate that J2 virus provides a transient mitogenic signal for LGL.

    Description: The activities carried out within Task 2 aim to collect, organize and synthesize geological, geomorphological, geotechnical and geophysical data for the location site of the Accelerometric National Network (RAN) stations in Italy, managed by the Department of Civil Protection. Knowledge of geological and geomorphological context, and the mechanical and dynamic characteristics of the stations subsoil is an important factor for studies on the attenuation laws and the choice of accelerograms related to the subsoil category provided by seismic code. Having to produce on a large number of sites (over 600), this knowledge have to be rationalized and homogenized so as to arrive at a common and comparable level of information. With this goal has been organized and implemented the activities within Task 2.

    Description: This report was prepared by Mr Edoardo Borgomeo during the summer pause of Imperial College (London, UK) lectures. Mr Borgomeo have joined the Istituto Nazionale di Geofisica e Vulcanologia (Italian Institute of Geophysics and Volcanology) for an internship under the supervision of Dr. Giuseppe Di Capua and Prof Silvia Peppoloni. This internship was an opportunity to gain an understanding on the functioning of a research institute and on the tasks a researcher has to undertake in the creation of a scientific publication. The result of the internship is presented in the following report that investigated the phenomenon of liquefaction under seismic conditions. The most serious direct effect of earthquakes on buildings and structures is ground shaking. However earthquake shocks might pose other hazards in the form of soil liquefaction, which can result in considerable financial losses. Some soils such as quicksands and quickclays can give rise to major problems when disturbed by ground shaking. The ground vibrations produced by an earthquake lead to a decrease in the effective stress and in the shear strength of the soil which in turn trigger the liquefaction.

    Description: The International Association for Promoting Geoethics (IAPG: http://www.geoethics.org) was founded on August 2012 to unite global geoscientists to raise the awareness of the scientific community regarding the importance of the ethical, social and cultural implications of geoscience research, education, and practice. IAPG is an international, multidisciplinary and scientific platform for discussion on ethical problems and dilemmas in Earth Sciences, promoting geoethical themes through scientific publications and conferences, strengthening the research base on geoethics, and focusing on case-studies as models for the development of effective and operative strategies. IAPG is legally recognized as a not-for-profit organization. It is a non-governmental, non-political, non-party institution, at all times free from racial, gender, religious or national prejudices. Its network continues to grow with more than 900 members in 103 countries, including 20 national sections. IAPG operates exclusively through donations and personal funds of its members. The results achieved since inception have been recognized by numerous international organizations. In particular, IAPG has obtained the status of affiliated organization by the International Union of Geological Sciences (IUGS), American Geosciences Institute (AGI), Geological Society of America (GSA), and the Geological Society of London (GSL). IAPG has enlarged its official relationships also through agreements on collaboration with other organizations, such as the American Geophysical Union (AGU), EuroGeoSurveys (EGS), European Federation of Geologists (EFG), Association of Environmental & Engineering Geologists (AEG), International Geoscience Education Organisation (IGEO), African Association of Women in Geosciences (AAWG), and others. IAPG considers publications as an indispensable activity to strengthen geoethics from a scientific point of view, so members are active in the publication of articles and editing of books on Geoethics with a peer-review process. Moreover, IAPG organizes sessions/symposia on geoethics in national and international congresses, thus encouraging a wide participation of the scientific community in the discussion on geoethical topics. This presentation provides an update on new results and numerous ongoing activities carried out by the IAPG with a brief look to future initiatives.

    Description: The activities carried out within Task 2 aim to collect, organize and synthesize geological, geomorphological, geotechnical and geophysical data for the location site of the Accelerometric National Network (RAN) stations in Italy, managed by the Department of Civil Protection, to improve the knowledge about the subsoil (see Delverable D05) and to permit a subsoil and topographic site classification based on EC8 categories. At the end of the project the subsoil of 695 stations have been classified using an hybrid approch, based on surface geology, spectral classification and Vs profils from different recording tecniques (DH, CH, MASW, ESAC). These activities have been useful to link the ITACA database with the software REXEL to select natural accelerograms, compatible with Norme Tecniche per le Costruzioni (NTC2008) and EUROCODE 8 (EC8) spectra, which may also reflect characteristics of the source in terms of magnitude and epicentral distance. For 688 station sites have been provided also a topographic classification using a GIS based semiautomatic method with “by-hand” corrections using topographic maps and/or Google Earth software. A Microsoft Excel Database which also allows to track all changes that have been made since the beginning of the project related to the site classification has been developed.

    Description: The paper focuses on the strong motion array deployed in the upper Aterno River Valley, in the immediate outskirts north-west of the town of L’Aquila, which is part of the Italian Strong Motion Network operated by the Department of Civil Protection. The array is composed of six accelerometric stations located along a cross section of the valley. The importance of this array relies on the fact that a large amount of high-quality records were obtained during the 2009 L’Aquila seismic sequence, from both the mainshock and several aftershocks. These data are especially important to investigate site effects in sediment-filled valleys during moderate earthquakes in epicentral area because well-documented observational studies are very limited in the literature. However, the main drawback for the study of site effects in the Aterno valley is the lack of a detailed knowledge of the geometry of the valley, soil layering and dynamic properties of materials. The main motivation for this study stems from the need to provide a reliable subsoil model of the valley coupled with high-quality strong motion data. Based on the above, in the framework of S4 project, a major effort was undertaken to get a trustworthy cross section of the valley by an ad hoc investigation, comprising geological and geotechnical surveys as well as an extensive geophysical campaign, characterized by both active and passive measurements. These results were complemented by additional geological and geotechnical data available in the literature. By merging all the information acquired, a 2D subsoil model of the transversal section of the upper Aterno valley has been produced. The valley is characterised by an asymmetric shape with a shallower rock basement at the western edge of the valley that deepens at the valley centre. Moreover, based on the results of geophysical tests, representative Vs values were assigned to the different lithologic units forming the alluvial deposits filling the valley. Shear wave velocity is a fundamental parameter for ground response studies and it is also effective in classifying the accelerometric station from a seismic point of view. The 2D model may be therefore, considered a benchmark model for future studies of site effects. It will offer the possibility to examine site effects with a complex underlying geology and to validate the results of numerical simulations of site response analyses with the numerous observations from earthquake recordings, both for weak and strong ground motion conditions.
