Geological setting and structural styles of Volcanic Massive Sulfide deposits in the northern Apennines (Italy): evidence for sea floor and sub-sea floor hydrothermal activity in unconventional ophiolites of the Mesozoic Tethys
Garuti, Giorgio;Bartoli, Omar;Scacchetti, Maurizio;Zaccarini, Federica;
Boletín de la Sociedad Geológica Mexicana , 2008,
Abstract: this paper is an overview of the geological setting and structural styles of cu-sulfide deposits of the vms-type, associated with tethyan ophiolites (the ligurides) in the northern apennines (italy). the italian deposits represent a rare example of vms associated with both the mantle-peridotite basement and the overlaying volcanic pile, within a single ophiolite sequence. this peculiar feature is due to the particular geodynamic evolution of the mesozoic ligurian ocean that allowed the upper mantle to be exposed on the seafloor for a long period before the outflow of morb-type lava and the deposition of pelagic sediments (cherts, palombini shales and calpionella limestones). middle to upper jurassic uprising of the basaltic magma initially provided the heath source for convective circulation of hydrothermal fluids through the overlaying mantle section, giving rise to sulfide deposition in crosscutting stockwork-veins and seafloor-stratiform ore bodies within the serpentinized mantle peridotite and the serpentinite breccia formed by submarine erosion of the upper mantle. the setting and structure of vms associated with the volcanic pile indicate that hydrothermal activity continued during and after the eruption of pillow basalts at the ocean floor, forming stockwork veins and conformable stratabound ore bodies within the basalt unit. furthermore, hydrothermal activity formed seafloor-stratiform deposits, at the top of the volcanic pile, covered with a thick horizon of cherts containing exhalative deposits of mn.
High and Low Temperature Gold Mineralizations in the Fe–Cu–Zn Sulfide Deposits of Corchia Ophiolite, Northern Italian Apennine
Zaccarini Federica,Giorgio Garuti
Minerals , 2013, DOI: 10.3390/min3010082
Abstract: Gold has been found in the Cyprus-type volcanogenic massive sulfide ore (VMS) deposits of Corchia ophiolite (Parma province, Italy) in the Cantiere Donnini, Speranza and Pozzo mining sites. At Cantiere Donnini and Speranza, the mineralization occurs at the contact between pillow lava and sedimentary rocks. The Pozzo mineralization is hosted by a serpentinite. Concentrations of gold up to 3070 ppb have been reported for the Cantiere Donnini and up to 6295 ppb in the Pozzo mine. According to the field relationships, gold composition, mineralogical assemblage and sulfur isotope data, we can conclude that two different types of gold mineralization have been recognized in the Corchia ophiolite: (1) formed at low temperature in submarine environment (Cantiere Donnini and Speranza) and (2) formed at high temperature in the oceanic mantle (Pozzo) by segregation of an immiscible sulfide liquid.
Cross compliance GAEC standards implemented in Italy: environmental effectiveness and strategic perspectives
Paolo Bazzoffi,Camillo Zaccarini Bonelli
Italian Journal of Agronomy , 2011, DOI: 10.4081/ija.2011.6.s1.e1
Abstract: The debate on the future of the Common Agricultural Policy (CAP), which is growing at European and National level, is notably and closely linked to the choices of EU related to the financial perspectives for the period 2014-2010. A public consultation on such topic has been started off by the EU Agriculture Commissioner Dacian Ciolo , who has left for the moment the two dossiers aside, giving priority to the identification of the agricultural policy post-2013 objectives. The debate on the new CAP reform, starting from the always ancient but modern general objectives which remained unchanged with the Lisbon Treaty, is now subject to an in-depth analysis and revision to identify new specific objectives in the wider framework of the European strategy 2010 identified by the EU executive body. However, the future outlooks can not neglect the need for stocktaking and what has been learned through the present and recent past experiences. In order to focus the theme of this special issue of the Italian Journal of Agronomy, we must remember that on 26th June 2003, EU farm ministers adopted a fundamental reform of the CAP and introduced a new single payment scheme (SPS, or Single Farm Payment) intended to change the way the EU supported its farm sector by removing the link between subsidies and production of specific crops. The Single Farm Payment is linked to meeting environmental, public, animal and plant health and animal welfare standards and the need to keep land in good agricultural and environmental condition. To gain funds from the SPS the Farmer has to cross comply - that is, to farm in an environmentally friendly way. COUNCIL REGULATION (EC) No 1782/2003 states that: Member States shall define, at national or regional level, minimum requirements for good agricultural and environmental condition on the basis of the framework set up in Annex IV, taking into account the specific characteristics of the areas concerned, including soil and climatic condition, existing farming systems, land use, crop rotation, farming practices, and farm structures.....
The happy celiac: An oxymoron or a possibility?  [PDF]
Maurizio Esposito
Health (Health) , 2012, DOI: 10.4236/health.2012.45041
Abstract: Background: Several international studies, confirmed in Italy too, show a hard presence of socio-relational problems inside the celiac population. Methods: Qualitative study involving persons with celiac disease and their families. 25 individual semi-structured interviews were conducted in three Italian regions. Results: Problems of management of social life for celiac persons are experienced, specially in the fields of: school, work, travels and life outside the home. Conclusion: Chronic illness is a “biographical disruption” [1] and the whole society has to be invested to fight the burden of celiac persons in their possibility of access to public life.
The Social World of Seafarers. A Sociological Research in Central Italy  [PDF]
Esposito Maurizio
Advances in Applied Sociology (AASoci) , 2013, DOI: 10.4236/aasoci.2013.34027
Abstract: Background: This article analyzes the social world of seafarers, with the aim of crossing the boundary defining the field of social sciences and entering the area of knowledge, where, to paraphrase Marcel Mauss, scientists argue for a place. Methods and Instruments: The research is based on an empirical study carried out at port authorities, fishermen’s cooperatives and fish markets in a few regions of central Italy during a two year period using empirical research methods utilized in fields of sociological knowledge, such as: semi-structured interviews, talks and informal conversations. The qualitative research was conducted through Computer Assisted Qualitative Data Analysis Software using the software Atlas.ti. Our attempt is to study in depth, through an empirical study conducted on a sample of 119 individuals, the heuristic subject on seafarers, in particular sailors and fishermen, specifically from a sociological point of view. The focus is an analysis of the life-worlds of these people in connection with variables such as the socio-economic characteristics of households, the relationship with the primary nuclear family, the element of solitude (in connection with individual feelings like melancholy and nostalgia), the relationship with peers and the crew. Results: From empirical research, it is seen that sailors and fishermen, despite their different local facets, represent a social world characterized by the richness of its material, social and symbolic expressions. The craft of the sea unites them, sometimes creating a subculture absolutely different from that of other populations and subcultures.
The Rehabilitation Role of Punishment in Prisons in Italy. Theoretical Development and Sociological Considerations  [PDF]
Maurizio Esposito
Sociology Mind (SM) , 2014, DOI: 10.4236/sm.2014.42018
Abstract:

This article deals with punishment and prisons, in particular, the rehabilitative role of punishment in Italian prisons. This role is herewith specified: On the one hand, by sociological considerations on punishment and prisons, based on the studies of Clemmer and Goffman; on the other hand, by international rules and the Italian legislation, dating back to the Reform of the Penitentiary Code 1975 and lastly, from a critical point of view. Generally speaking, the term rehabilitative model in this context means to restore solidarity with the socially recognized values, reconstructing the broken citizenship bond.

Suicidal Risk in Italian Prisons. A Population-Based Cohort Study  [PDF]
Maurizio Esposito
Sociology Mind (SM) , 2018, DOI: 10.4236/sm.2018.81004
Abstract: The article deals with the problem of suicidal risk in Italian prisons. Beginning with a general analysis of the concept and the sociological approaches to suicide, we analyze the main studies on suicide in Italian penal institutions. We present updated Italian prisoners suicide statistics (2002-2015), which we then analyze and discuss both in absolute numbers and in percentage terms. The results indicate that the situation is critical: suicide is the leading cause of death in Italian prisons. The problem mainly affects Italian elder prisoners, the weakest group for mental and physical health. The trend data for female detainees reveal that the ability to adapt to prison life appears more difficult than for male detainees. In addition, suicide among foreign detainees has risen in recent years; a probable contributing factor is the inability to use alternative measures such as house arrest. The conclusion attests a need to provide health policies with treatment options for the cure and care of prisoners in difficulty, with a total approach responding not only to the specific symptoms or to risk behaviors but also to the whole person in a holistic sense.
Experimental Assessment of the Battery Lifetime in WSN Based on the Duty-Cycle Current Average Method  [PDF]
Leonardo Barboni, Maurizio Valle
Wireless Sensor Network (WSN) , 2014, DOI: 10.4236/wsn.2014.610021
Abstract: A great amount of work addressed methods for predicting the battery lifetime in wireless sensor systems. In spite of these efforts, the reported experimental results demonstrate that the duty-cycle current average method, which is widely used to this aim, fails in accurately estimating the battery life time of most of the presented wireless sensor system applications. The aim of this paper is to experimentally assess the duty-cycle current average method in order to give more effective insight on the effectiveness of the method. An electronic metering system, based on a dedicated PCB, has been designed and developed to experimentally measure node current consumption profiles and charge extracted from the battery in two selected case studies. A battery lifetime measurement (during 30 days) has been carried out. Experimental results have been assessed and compared with estimations given by using the duty-cycle current average method. Based on the measurement results, we show that the assumptions on which the method is based do not hold in real operating cases. The rationality of the duty-cycle current average method needs reconsidering.
Proton Therapy Results in the Treatment of Hepatocellular Carcinoma According to the Barcelona-Clinic Liver Cancer (BCLC) Staging System  [PDF]
Francesco Dionisi, Maurizio Amichetti
International Journal of Medical Physics,Clinical Engineering and Radiation Oncology (IJMPCERO) , 2015, DOI: 10.4236/ijmpcero.2015.42013
Abstract:
Proton therapy represents the most advanced form of radiotherapy currently available. Hepato-cellular carcinoma (HCC) has been extensively treated with proton therapy since 1983 with en-couraging results in terms of effectiveness and safety, as reported in recent research articles, systematic reviews and meta-analyses. In this report, we summarized for the first time the results of proton therapy treatment for HCC according with respect to the Barcelona Clinic Liver Cancer Staging System, the most adopted classification system for HCC which provides information on both prognostic prediction and treatment allocation.
Parenthood and the Wayana People  [PDF]
Maurizio Alì, Rodica Ailincai
Sociology Mind (SM) , 2016, DOI: 10.4236/sm.2016.63013
Abstract: This paper presents the first results obtained from an exploratory study which is conducted within the Amerindian Wayana communities who inhabit the Amazon sector of the High Maroni area, in French Guiana. Based on an ecological and interactionist approach and employing comprehensive methods to analyze observed facts (to bypass the nostalgic attitude fostering the paradigmatic anthropological dichotomy “tradition vs; modernity”), this study describes educational family practices among Wayana and analyses parents’ expectations visà-vis their children in the framework of the postcolonial dynamic, with the aim to understand the influence of the national public policies to diffuse certain domestic praxis. The ethnographic corpus is gathered during a long fieldwork and it is accompanied by seventeen semi-open interviews. The interpretative approach attempts to link the observed behaviours observed to contextual and cultural variables. Following the analysis of the data, the authors propose 1) a diagram of the structure of Wayana family kinship Microsystems (with a description and a diagram of the Wayana matrilineality scheme); 2) a description of roles and educational functions within their communities and, finally, 3) an overview of parental expectations interpreted taking into account the influences of contemporary inter-systemic interactions (and above all the dynamics generated by the recent introduction of compulsory schooling into the area).
