RENDICONTO SULL’ATTIVITA’ DI SORVEGLIANZA SVOLTA NEL 2008 (1 Gennaio – 31 Dicembre 2008)MISURE GRAVIMETRICHE AI CAMPI FLEGREI

Nel 2008 sono state effettuate due campagne gravimetriche ai Campi Flegrei; la prima nel mese di febbraio, la seconda dal 20 ottobre al 11 novembre. In entrambre le campagne le misure sono state rilevate sull’intera rete che, nel corso della secondo rilevamento, è stata amplianta con l’istituzione di due nuovi vertici posizionati lungo la linea costiera, e precisamente tra le stazioni di Bagnoli e La Pietra

RENDICONTO SULL’ATTIVITA’ DI SORVEGLIANZA SVOLTA NEL 2008 (1 Gennaio – 31 Dicembre 2008) MISURE GRAVIMETRICHE AL VESUVIO

Nel corso del 2008 sono state eseguite due campagne gravimetriche nell’area vesuviana; la prima nel mese di aprile, la seconda a cavallo dei mesi di novembre e dicembre. In entrambe le campagne, i dati sono stati rilevati su 31 dei 32 vertici costituenti la rete in quanto la stazione “Baracche Forestali”, ubicata lungo la linea che corre all’interno della Forestale, è andata distrutta nel 2007 a causa di lavori di ripristino nell’area

PHOTOGRAMMETRIC PROCESSING AND FRUITION OF PRODUCTS IN OPEN-SOURCE ENVIRONMENT APPLIED TO THE CASE STUDY OF THE ARCHAEOLOGICAL PARK OF POMPEII

Abstract. The paper presents the geomatic survey campaign carried out in the Domus V of Pompeii Archaeological site, the photogrammetric processing of the collected images and the following fruition of the deriving products deploying open-source software. Among all the produced results, the orthophotos of the vertical walls of one of the Domus V rooms are made available through a "master/slave" GIS environment, where each orthophoto is uploaded in a "slave" project whose visualization is triggered by querying the corresponding geometry representing the wall in the "master" project. This strategy allows to include the display of the third dimension, i.e., the altimetric one, within a traditional GIS environment, so to constitute a 3D GIS representation. This is particularly useful to realize a catalogue of all the archaeological site in the future to be viewed, queried and exploited also by non-specialists in geomatics or archaeology fields of knowledge

Coulomb's law modification in nonlinear and in noncommutative electrodynamics

We study the lowest-order modifications of the static potential for Born-Infeld electrodynamics and for the $\theta$-expanded version of the noncommutative U(1) gauge theory, within the framework of the gauge-invariant but path-dependent variables formalism. The calculation shows a long-range correction ($1/r^5$-type) to the Coulomb potential in Born-Infeld electrodynamics. However, the Coulomb nature of the potential (to order $e^2$) is preserved in noncommutative electrodynamics.Comment: 14 pages, 1 figur

What if cancer survival in Britain were the same as in Europe: how many deaths are avoidable?

OBJECTIVE: To estimate the number of deaths among cancer patients diagnosed in Great Britain that would be avoidable within 5 years of diagnosis if the mean (or highest) survival in Europe for patients diagnosed during 1985-1989, 1990-1994 and 1995-1999 were achieved. DESIGN: Five-year relative survival for cancers in Great Britain compared with that from other countries in the EUROCARE-2, -3 and -4 studies. Calculation of excess deaths (those more than expected from mortality in the general population) that would be avoidable among cancer patients in Britain if relative survival were the same as in Europe. SETTING: Great Britain (England, Wales, Scotland) and 13 other European countries. SUBJECTS: 2.8 million adults diagnosed in Britain with 1 of 39 cancers during 1985-1989 (followed up to 1994), 1990-1994 (followed up to 1999) and 1995-1999 (followed up to 2003). MAIN OUTCOME MEASURE: Annual number of avoidable deaths within 5 years of diagnosis. Percentage of the excess (cancer-related) deaths among cancer patients that would be avoidable. RESULTS: Compared with the mean European 5-year relative survival, the largest numbers of avoidable deaths for patients diagnosed during 1985-1989 were for cancers of the breast (about 18% of the excess mortality from this cancer, 7541 deaths), prostate (14%, 4285), colon (9%, 4090), stomach (8%, 3483) and lung (2%, 3548). For 1990-1994, the largest numbers of avoidable deaths were for cancers of the prostate (20%, 7335), breast (15%, 6165), colon (9%, 4376), stomach (9%, 3672), lung (2%, 3735) and kidney (22%, 2644). For 1995-1999, most of the avoidable deaths were for cancers of the prostate (17%, 5758), breast (15%, 5475), lung (3%, 4923), colon (10%, 4295), stomach (9%, 3137) and kidney (21%, 2686).Overall, some 6600-7500 premature deaths would have been avoided each year among cancer patients diagnosed in Britain during 1985-1999 if the mean survival in Europe had been achieved. This represents 6-7% of cancer-related mortality. Compared with the highest European survival, avoidable premature mortality among cancer patients fell from about 12 800 deaths a year (12.2% of cancer-related mortality) to about 11 400 deaths a year (10.6%) over the same period.A large component of the avoidable mortality is due to prostate cancer: excluding this cancer from comparison with the European mean survival reduces the annual number of avoidable deaths by 1000-1500, and the percentage of excess mortality by up to 1%. Compared with the highest survival, the annual number of avoidable deaths would be 1500-2000 fewer, and 1-2% lower as a percentage of excess mortality, but the overall trend in avoidable premature mortality among cancer patients would be similar, falling from 11.4% (1985-1989) to 10.3% (1990-1994) and 9.7% for those diagnosed during 1995-1999.For several cancers, survival in Britain was slightly higher than the mean survival in Europe; this represented some 110-180 premature deaths avoided each year during the period 1985-2003. CONCLUSIONS: Avoidable premature mortality among cancer patients diagnosed in Britain during 1985-1999 has represented 6-7% of cancer-related mortality compared with the mean survival in Europe. Compared with the highest levels of survival in Europe, the reduction from 12.2% to 10.6% of cancer-related mortality reflects small but steady progress over the period 1985-2003

The new IMGC-02 transportable absolute gravimeter: measurement apparatus and applications in geophysics and volcanology

The research carried out at the Istituto Nazionale di Ricerca Metrologica (formerly Istituto di Metrologia «G. Colonnetti») aiming to develop a transportable ballistic absolute gravimeter ended with a new version of the instrument, called the IMGC-02. It uses laser interferometry to measure the symmetrical free rising and falling motion of a test mass in the gravity field. Providing the same accuracy achieved with previous versions, the instrumental improvements mainly concern size, weight, data processing algorithms and operational simplicity. An uncertainty of 9 μGal (1 μGal=1×10–8 m·s−2) can be achieved within a single observation session, lasting about 12 h, while the time series of several observation sessions show a reproducibility of 4 μGal. At this level, gravity measurements provide useful information in Geophysics and Volcanology. A wide set of dynamic phenomena, i.e. seismicity and volcanic activity, can produce temporal gravity changes, often quite small, with an amplitude ranging from a few to hundreds of microgals. Therefore the IMGC absolute gravimeter has been employed since 1986 in surveying the Italian active volcanoes. A brief history of the gravimeter and the description of the new apparatus, together with the main results of ongoing applications in Geophysics and Volcanology are presented

Relationship between Breast Cancer Surgical Treatment and Psychiatric Symptomatology: Which Sociodemographic and Clinical Factors Could Influence It? A Preliminary Study

This study aimed to investigate psychiatric symptomatology in a sample of patients affected by breast cancer undergoing surgery, evaluating the potential mediators on perceived stress levels, depression and hopelessness. The study was conducted on eighty-five patients with breast cancer, admitted consecutively to the Breast Unit of the IRCCS Ospedale Policlinico San Martino, between May 2018 and December 2019. Sociodemographic (age of diagnosis, gender, marital and occupational status, educational level, having children) and clinical (type and side of surgery, previous breast surgery, neoadjuvant chemotherapy and axillary dissection) characteristics were investigated through a semi-structured interview. The following rating scales were administered: Beck Depression Inventory, Beck Hopelessness Scale, and Perceived Stress Scale. Our findings indicate that the presence of children and of a partner was associated with a lower total score on the clinical dimensions evaluated. Furthermore, we found demolitive surgery to be a mediator between perceived stress and hopelessness, while history of previous breast surgery was found to be a mediator between demolitive surgery and perceived stress. In conclusion, patients affected by breast cancer undergoing more complex and demolitive surgery or with history of previous breast surgery should be mostly monitored from a psychological and psychiatric point of view from the beginning of treatments to evaluate the first manifestations of psychiatric symptomatology
