Il significato e la concezione della divinità tutelare cittadina nella religione romana

Con l’evocatio i Romani privavano le città assediate, prima di espugnarle, delle loro divinità tutelari. I casi documentati o probabili riguardano: Giunone Regina (Veio), Giunone Celeste (Cartagine), Giunone Curite (Faleri) e Voltumna (Volsini). Altri problemi interessanti emergono dallo studio delle figure di Minerva Capta e della divinità tutelare di Isaura Vetus. L’indagine del rito porta anche a considerare il peculiare vincolo che univa gli dèi romani al luogo, espresso in maniera efficace dal genius e dalla misteriosa figura della divinità tutelare segreta di Roma.Through the evocatio the Romans deprived the besieged cities of their tutelary deities, before conquering them. The documented or likely cases concern: Iuno Regina (Veii), Iuno Caelestis (Carthago), Iuno Curiti

Local Triangle Choice for Impact Computation in the Tactile Exploration of a Virtual Surface

Evaluating the intersection of the trajectory of the exploring finger, with the virtual surface representing the scene, is a key problem in the VIDET project of an aid for the visually impaired. A substitute for Delaunay triangulation, which permits of local computation for that goal, is proposed

Jörg Rüpke, Pantheon. Una nuova storia della religione romana

Jörg Rüpke (d’ora in poi R.), titolare della cattedra di Vergleichende Religionswissenschaft presso l’Università di Erfurt in Germania, è da tempo una figura di riferimento nel campo degli studi sulla religione romana. Il presente volume è allo stesso tempo il manifesto, la sintesi ed un (primo) ponderoso bilancio del progetto di ricerca ERC intitolato LAR: Lived Ancient Religion, da R. diretto e coordinato tra il 2012 e il 2017. Tale progetto ha voluto proporre un approccio più che un metod..

High Density Lipoproteins Inhibit Oxidative Stress-Induced Prostate Cancer Cell Proliferation

Recent evidence suggests that oxidative stress can play a role in the pathogenesis and the progression of prostate cancer (PCa). Reactive oxygen species (ROS) generation is higher in PCa cells compared to normal prostate epithelial cells and this increase is proportional to the aggressiveness of the phenotype. Since high density lipoproteins (HDL) are known to exert antioxidant activities, their ability to reduce ROS levels and the consequent impact on cell proliferation was tested in normal and PCa cell lines. HDL significantly reduced basal and H2O2-induced oxidative stress in normal, androgen receptor (AR)-positive and AR-null PCa cell lines. AR, scavenger receptor BI and ATP binding cassette G1 transporter were not involved. In addition, HDL completely blunted H2O2-induced increase of cell proliferation, through their capacity to prevent the H2O2-induced shift of cell cycle distribution from G0/G1 towards G2/M phase. Synthetic HDL, made of the two main components of plasma-derived HDL (apoA-I and phosphatidylcholine) and which are under clinical development as anti-atherosclerotic agents, retained the ability of HDL to inhibit ROS production in PCa cells. Collectively, HDL antioxidant activity limits cell proliferation induced by ROS in AR-positive and AR-null PCa cell lines, thus supporting a possible role of HDL against PCa progression

Remote Colorimetric and Structural Diagnosis by RGB-ITR Color Laser Scanner Prototype

Since several years ENEA's Artificial Vision laboratory is involved in electrooptics systems development. In the last period the efforts are concentrated on cultural heritage remote diagnosis, trying to develop instruments suitable for multiple purposes concerning restoration, cataloguing, and education. Since last five years a new 3D (three-dimensional) laser scanner prototype (RGB-ITR) based on three amplitude-modulated monochromatic laser sources mixed together by dichroic filters is under development. Five pieces of information per each sampled point (pixel) are collected by three avalanche photodiodes and dedicated electronics: two distances and three target reflectivity signals for each channel, red, green, and blue. The combination of these pieces of information opens new scenarios for remote colorimetry allowing diagnoses without the use of scaffolds. Results concerning the use of RGB-ITR as colorimeter are presented

The Effect of Simple Melodic Lines on Aesthetic Experience: Brain Response to Structural Manipulations

This fMRI study investigates the effect of melody on aesthetic experience in listeners na \u308\u131ve to formal musical knowledge. Using simple melodic lines, whose syntactic structure was manipulated, we created systematic acoustic dissonance. Two stimulus categories were created: canonical (syntactically \u201ccorrect,\u201d in the Western culture) and modified (made of an altered version of the canonical melodies). The stimuli were presented under two tasks: listening and aesthetic judgment. Data were analyzed as a function of stimulus structure (canonical and modified) and stimulus aesthetics, as appraised by each participant during scanning. The critical contrast modified versus canonical stimuli produced enhanced activation of deep temporal regions, including the parahippocampus, suggesting that melody manipulation induced feelings of unpleasantness in the listeners. This was supported by our behavioral data indicating decreased aesthetic preference for the modified melodies. Medial temporal activation could also have been evoked by stimulus structural novelty determining increased memory load for the modified stimuli. The analysis of melodies judged as beautiful revealed that aesthetic judgment of simple melodies relied on a fine-structural analysis of the stimuli subserved by a left frontal activation and, possibly, on meaning attribution at the charge of right superior temporal sulcus for increasingly pleasurable stimul

Maternal and Neonatal Behaviour in Italian Mediterranean Buffaloes

The aim of this study was to describe the neonatal and maternal behaviour of Italian Mediterranean buffaloes. Thirty primiparous buffaloes were moved into individual pens 12.5 (±2.5) days before calving. Maternal and neonatal behaviours were recorded for 48 h after calving and the analysis was performed in continuous sampling with the software BORIS. Calves’ clinical evaluations (temperature, weight, and heart and respiratory rates) were performed at different time intervals and correlated with behavioural data from the dam. Data were analysed with parametric and non-parametric methods after controlling their distribution. The maternal behavioural pattern found highlighted buffaloes’ priorities during the post-partum period: firstly, they stand and start grooming to ensure proper care for the calf; it is only after this that they dedicate time to maintenance behaviours (feeding and lying). The dams mainly groomed the calf during the first six hours after calving (average time in the 1–6-h interval: 7.7 ± 2.5 min., F = (2.5, 60.2) = 75.0; p < 0.001) to ensure the formation of the mother–infant bond; thereafter, the behaviour decreased over time. As reported in the literature, inexperienced mothers could sometimes delay the calf’s first suckling with aggressive or rejection behaviours. In this regard, 16 buffalo dams showed at least one maternal rejection behaviour, which was found to negatively correlate with calves’ daily weight gain (DWG) at 14 (rs = −0.5, p = 0.02) and 21 days (rs = −0.7, p < 0.001). The calves took on average 212.0 ± 110.0 min to suckle, and this behaviour was mainly shown during the first six hours. Overall, suckling behaviour was correlated with standing: (rs = 0.6, p < 0.001) and walking (rs = 0.9, p < 0.001). The calves’ live weight and DWG were consistently higher than the values reported in the literature. Our results present a detailed description of maternal and neonatal behaviour in the early post-partum period in Italian Mediterranean buffaloes. We also found that maternal rejection behaviours can negatively influence the calves’ growth. Finally, we think that such results can improve the management of buffaloes during the period around parturition

A randomized comparison trial of two and four-step approaches to teaching Cardio-Pulmonary Reanimation

Background and aim of the work: The treatment of cardiac arrest in an extra-hospital environment improves with the increase in the number of people able to establish an early Cardio-Pulmonary Reanimation (CPR). The main aim of the study was to assess the validity of the two-step method in case of prolonged CPR. Methods: A randomized comparison study was conducted in the University Nursing School of a Northern Italian town, during the 2015/16 academic year, among 60 students, to teach them CPR techniques, through two different teaching methods (4-step and the 2-step of CPR training). The effectiveness of the maneuvers performed on mannequins equipped with skill-meter was verified. Results: Our study did not highlight any significant difference between the two methods of CPR training. The comparison between the two methods regarding their efficacy in practical teaching of CPR, highlighted by this study, proved the validity of both the 4-minute continuous method (1st method) and the 30:2 method (2nd method). Conclusions: The results of the study showed no differences between the 2-step and the 4-step methods, in the effectiveness of cardiac massage. The correct execution of chest compressions during a CPR is the key to increase the patient’s chances of rescue. Research has shown that any interruption in the execution of chest compressions, leads to a progressive reduction of the effectiveness of cardiac massage, with negative consequences on the prognosis of the patient undergoing at CPR
