The free license codes as decision support system (DSS) for the emergency planning to simulate radioactive releases in case of accidents in the new generation energy plants

The radiological risk is related to a wide range of activities, beginning with the medical and military ones and including those connected to the industrial and research activities such as nuclear fusion. A valid tool to predict the consequences of the accidents and reduce the risk is represented by computing systems that allow modeling the evolution of a possible release of radioactive materials over time and space. In addition to proprietary codes there are free license codes, like Hot-Spot, that allow providing a set of tools to simulate diffusion in case of accidents involving radioactive materials and analyze the safety and security of the facilities in which the radioactive material is manipulated. The case studies scenario’s consists in two simulations accidents scenario the first to biomass plant and the second at nuclear fission plant. The simulation of the radioactive contamination have been conducted with the code HOT SPOT, a free license code. The results of the simulation and data discussion will be presented in this work by the authors

Integrated multidisciplinary ecological analysis from the Uluzzian settlement at the Uluzzo C Rock Shelter, south-eastern Italy

open20siThe Middle to Upper Palaeolithic transition, between 50 000 and 40 000 years ago, is a period of important ecological and cultural changes. In this framework, the Rock Shelter of Uluzzo C (Apulia, southern Italy) represents an important site due to Late Mousterian and Uluzzian evidence preserved in its stratigraphic sequence. Here, we present the results of a multidisciplinary analysis performed on the materials collected between 2016 and 2018 from the Uluzzian stratigraphic units (SUs) 3, 15 and 17. The analysis involved lithic technology, use-wear, zooarchaeology, ancient DNA of sediments and palaeoproteomics, completed by quartz single-grain optically stimulated luminescence dating of the cave sediments. The lithic assemblage is characterized by a volumetric production and a debitage with no or little management of the convexities (by using the bipolar technique), with the objective to produce bladelets and flakelets. The zooarchaeological study found evidence of butchery activity and of the possible exploitation of marine resources, while drawing a picture of a patchy landscape, composed of open forests and dry open environments surrounding the shelter. Ancient mitochondrial DNA from two mammalian taxa were recovered from the sediments. Preliminary zooarchaeology by mass spectrometry results are consistent with ancient DNA and zooarchaeological taxonomic information, while further palaeoproteomics investigations are ongoing. Our new data from the re-discovery of the Uluzzo C Rock Shelter represent an important contribution to better understand the meaning of the Uluzzian in the context of the Middle/Upper Palaeolithic transition in south-eastern Italy.First published: 13 July 2021openSARA SILVESTRINI, MATTEO ROMANDINI, GIULIA MARCIANI, SIMONA ARRIGHI, LISA CARRERA, ANDREA FIORINI, JUAN MANUEL LÓPEZ-GARCÍA, FEDERICO LUGLI, FILOMENA RANALDO, VIVIANE SLON, LAURA TASSONI, OWEN ALEXANDER HIGGINS, EUGENIO BORTOLINI, ANTONIO CURCI, MATTHIAS MEYER, MICHAEL CHRISTIAN MEYER, GREGORIO OXILIA, ANDREA ZERBONI, STEFANO BENAZZI, SPINAPOLICE ENZA ELENASARA SILVESTRINI, MATTEO ROMANDINI, GIULIA MARCIANI, SIMONA ARRIGHI, LISA CARRERA, ANDREA FIORINI, JUAN MANUEL LÓPEZ-GARCÍA, FEDERICO LUGLI, FILOMENA RANALDO, VIVIANE SLON, LAURA TASSONI, OWEN ALEXANDER HIGGINS, EUGENIO BORTOLINI, ANTONIO CURCI, MATTHIAS MEYER, MICHAEL CHRISTIAN MEYER, GREGORIO OXILIA, ANDREA ZERBONI, STEFANO BENAZZI, SPINAPOLICE ENZA ELEN

Sawmark Analysis of Three Cases of Amputation and a Craniotomy from the Seventeenth and Eighteenth Centuries Hospital Necropolis of Forlì Campus (Forlì, Italy)

The seventeenth-eighteenth century hospital necropolis of Forlì Campus (Forlì, Italy) was discovered during the Forlì Campus building work in 2014. Three cases of limb amputation and a craniotomy are examined using the forensic approach of sawmark analysis in order to understand features of the surgical instruments employed and to gain insight into the position of the surgeon during the cutting actions. With the aid of high definition photographs and moulds, we analyzed the cut surfaces of each sample, also using stereomicroscopy and SEM (Scanning Electron Microscopy). A qualitative and quantitative approach was used in the analysis of the kerf features (e.g. breakaway spur and notch, tooth scratches and hop, exit chipping), and empirical evidence was compared against comparisons coeval surgical essays. We hypothesize that a linear hand-powered push saw and an alternated push saw with a 2mm distance between the teeth were used for amputations. The craniotomy was executed presumably using a linear hand-powered saw with the set of the blade circa 1.3mm wide. Through the application of forensic methods on individuals from archaeological context we describe early cases of surgical practice in a more technical way

Lack of p53 decreases basal oxidative stress levels in the brain through upregulation of thioredoxin-1, biliverdin reductase-A, manganese superoxide dismutase, and nuclear factor kappa-B

The basal oxidative and nitrosative stress levels measured in cytosol, mitochondria, and nuclei as well as in the whole homogenate obtained from the brain of wild type (wt) and p53 knockout [p53((-/-))] mice were evaluated. We hypothesized that the loss of p53 could trigger the activation of several protective mechanisms such as those involving thioredoxin-1 (Thio-1), the heme-oxygenase-1/biliverdin reductase-A (HO-1/BVR-A) system, manganese superoxide dismutase (MnSOD), the IkB kinase type \u3b2 (IKK\u3b2)/nuclear factor kappa-B (NF-kB), and the nuclear factor-erythroid 2 (NF-E2) related factor 2 (Nrf-2)

Shared language, diverging genetic histories: high-resolution analysis of Y-chromosome variability in Calabrian and Sicilian Arbereshe

none14noThe relationship between genetic and linguistic diversification in human populations has been often explored to interpret some specific issues in human history. The Albanian-speaking minorities of Sicily and Southern Italy (Arbereshe) constitute an important portion of the ethnolinguistic variability of Italy. Their linguistic isolation from neighboring Italian populations and their documented migration history, make such minorities particularly effective for investigating the interplay between cultural, geographic and historical factors. Nevertheless, the extent of Arbereshe genetic relationships with the Balkan homeland and the Italian recipient populations has been only partially investigated. In the present study we address the genetic history of Arbereshe people by combining highly resolved analyses of Y-chromosome lineages and extensive computer simulations. A large set of slow- and fast-evolving molecular markers was typed in different Arbereshe communities from Sicily and Southern Italy (Calabria), as well as in both the putative Balkan source and Italian sink populations. Our results revealed that the considered Arbereshe groups, despite speaking closely related languages and sharing common cultural features, actually experienced diverging genetic histories. The estimated proportions of genetic admixture confirm the tight relationship of Calabrian Arbereshe with modern Albanian populations, in accordance with linguistic hypotheses. On the other hand, population stratification and/or an increased permeability of linguistic and geographic barriers may be hypothesized for Sicilian groups, to account for their partial similarity with Greek populations and their higher levels of local admixture. These processes ultimately resulted in the differential acquisition or preservation of specific paternal lineages by the present-day Arbereshe communities.noneSarno, Stefania; Tofanelli, Sergio; De Fanti, Sara; Quagliariello, Andrea; Bortolini, Eugenio; Ferri, Gianmarco; Anagnostou, Paolo; Brisighelli, Francesca; Capelli, Cristian; Tagarelli, Giuseppe; Sineo, Luca; Luiselli, Donata; Boattini, Alessio; Pettener, DavideSarno, Stefania; Tofanelli, Sergio; De Fanti, Sara; Quagliariello, Andrea; Bortolini, Eugenio; Ferri, Gianmarco; Anagnostou, Paolo; Brisighelli, Francesca; Capelli, Cristian; Tagarelli, Giuseppe; Sineo, Luca; Luiselli, Donata; Boattini, Alessio; Pettener, David
