Antigone : dal mito al teatro, dal teatro al mito

The success of Sophocles\u2019 Antigone has been such that it has set a thorough standard for reception: in order to fully grasp the significance of the reception process and to appreciate the influence of Antigone on the whole of Western culture, we must follow the character\u2019s journey from its beginning, through the first stagings to its reception in the nineteenth and twentieth centuries. The present essay follows Antigone\u2019s long itinerary in the attempt to identify the landmarks in the reception of the myth, the breaks that have changed the lines of the character, as well as its contemporary outputs. A myth made into drama, Antigone has become a real critical myth

Hormonal responses to water deficit in cambial tissues of Populus alba L.

Changes of the concentration of bioactive gibberellins and abscisic acid in the cambial region of white poplar (Populus alba L.) were investigated in one-year-old plants, to highlight how these phytohormone signals are modulated in response to water deficit. Plants were cultivated in pots outdoor and, at the time of maximum cambial growth (T0), irrigation was withdrawn for 8 d, inducing a mild water deficit, thus mimicking a condition that is recurrent in mediterranean climates when white poplar attains its maximum growth rate. The water deficit was suspended by resuming irrigation (Tmax), throughout a recovery period of two weeks (Trec). Cambial tissues were sampled at T0, Tmax and Trec. Significant changes of leaf and stem relative water content, leaf water potential, stomatal conductance, transpiration, carbon assimilation, stem shrinkage and leaf number were induced by soil water shortage, which also negatively affected cambium development. Nevertheless, these responses were almost fully reversed following the resumption of irrigation. Water deficit induced the accumulation of large amounts of abscisic acid in cambial tissues, but the hormone was brought back to pre-stress levels after the recovery period. With regard to bioactive gibberellins, GA1 was several fold more abundant than GA4 and reached the greatest level in the plants recovering from the water status imbalance. The possible functions of gibberellins and abscisic acid in the response of cambial tissues to water deficit are discussed in view of the known physiological roles and molecular mechanisms of action of these hormonal signals

The global symmetry index, symmetry index, quality index and kinematics of the gait cycle with the synchronized contribution of the latest generation magneticinertial and electromyographic technology. Practical surveys and planning hypotheses for the revision of gesture.

The walk is certainly the cornerstone of human mobility. The literature has focused on the qualitative and quantitative analysis of walking and how certain parameters can change after an aerobic fatigue test. Our research proposal is based, in an innovative way in literature, on the analysis of specific parameters of the gait cycle, considered highly significant, such as the global symmetry index, the symmetry index, the quality index of the gait cycle, pelvic kinematics and muscle activation and the differences in these parameters before and after an aerobic fatigue test (resistance of the gesture over time). A total of 27 male athletes, aged (9-11) participated to the study, in which state-of-the-art equipment was used in the field of movement sciences that includes a device that integrates triaxial inertial sensors and a set of synchronized wireless probes, part of fourth generation instruments, still the most advanced on the market, for wireless surface electromyographic analysis. Thanks to these devices it was possible to carry out an evaluation of the subjects directly, with the live acquisition of data during the entire execution of the test protocol, allowing to evaluate the aforementioned parameters, which are considered strategic in pre-adolescent age, both for a more accurate basic construction of the element sure to offer a better planning of work sessions or training sessions at the time and in the future, also in consideration of periods immediately following high workloads, where fatigue affects the precision of gestures in the young athlete with various consequences, including significant ones, which is not always taken into consideration

Determining the optimal piecewise constant approximation for the nonhomogeneous Poisson process rate of Emergency Department patient arrivals

Modeling the arrival process to an Emergency Department (ED) is the first step of all studies dealing with the patient flow within the ED. Many of them focus on the increasing phenomenon of ED overcrowding, which is afflicting hospitals all over the world. Since Discrete Event Simulation models are often adopted to assess solutions for reducing the impact of this problem, proper nonstationary processes are taken into account to reproduce time–dependent arrivals. Accordingly, an accurate estimation of the unknown arrival rate is required to guarantee the reliability of results. In this work, an integer nonlinear black–box optimization problem is solved to determine the best piecewise constant approximation of the time-varying arrival rate function, by finding the optimal partition of the 24 h into a suitable number of not equally spaced intervals. The black-box constraints of the optimization problem make the feasible solutions satisfy proper statistical hypotheses; these ensure the validity of the nonhomogeneous Poisson assumption about the arrival process, commonly adopted in the literature, and prevent mixing overdispersed data for model estimation. The cost function of the optimization problem includes a fit error term for the solution accuracy and a penalty term to select an adequate degree of regularity of the optimal solution. To show the effectiveness of this methodology, real data from one of the largest Italian hospital EDs are used

Laser-driven production with advanced targets of Copper-64 for medical applications

Radionuclides are of paramount importance in nuclear medicine both for clinical uses and radiopharmaceutical production. Among the others, nuclides suitable for theranostics like Copper-64 are particularly attractive since they can play both a diagnostic and therapeutic role. In the last years, the growing demand for these nuclides stimulated the research of new solutions, along with cyclotrons already in use, for their production. In this respect, a promising alternative is laser-driven proton accelerators based on the interaction of superintense laser pulses with target materials. Because of their potential compactness and flexibility, they are under investigation for several applications ranging from materials science to nuclear medicine. Moreover, the use of advanced Double-Layer targets (DLTs) was identified as a viable route to increase the number and energy of the accelerated protons to satisfy the requirements of demanding applications. In this contribution, we numerically investigate the use of DLT-based laser-driven sources for Copper-64 production. We show that activities relevant to pre-clinical studies can be achieved with an existing 150 TW laser and DLTs. Moreover, we extend the discussion by considering a broad range of laser systems by exploiting a theoretical model. Our results can guide the choice of laser and target parameters for future experimental investigations

Recalling an unfair experience reduces adolescents’ dishonest behavioral intentions: The mediating role of justice sensitivity

This is the author accepted manuscript. The final version is available from Springer Verlag via the DOI in this record.Injustice experiences are likely to have a strong impact on—adolescents' life. However, individuals differ in how they perceive and respond to injustice depending on their justice sensitivity. Whereas several studies analyzed the relationships between justice sensitivity and antisocial behaviors in adult samples, little is known about this relationship among adolescents. The aim of the present experimental study is to expand knowledge on the antecedents and effects of justice sensitivity from the Victim (i.e., JS-Victim) and Others (i.e., JS-Observer, Perpetrator, and Beneficiary) perspective, particularly with regard to its relationship to willingness to act in dishonest behavioral intentions (e.g., stealing money or objects from classmates, teachers, or strangers). The study involved 369 Italian students (52% males; Mage = 16.64, SD = 1.78). We examined the role of justice sensitivity in the relationship between the recall of unfair, fair, or neutral episodes, and the consequent willingness to perform dishonest behaviors. Results demonstrate that recalling unfair (vs. fair or neutral) episodes leads to an increase in JS-Others, which in turn decreased willingness to behave dishonestly. Conversely, JS-Victim did not mediate the relationship between the recall of unfair episodes and intentions to behave dishonestly. The present findings suggest that during adolescence JS-Others might act as a protective factor against dishonest behaviors.This study was made possible due a FIRB 2012 grant from the Italian Ministry of Education, University and Research (MIUR; Grant Number RBFR128CR6)

Football training program and injury prevention program WTA: a season of analysis with IT management Weakrisk Sporstsolutions in Italan élite football players third division (Serie C).

Purpose: The aim of this study is analyze the relationship with training program and injury prevention program in professional football players during competitive season in AJ Fano Calcio 1906 srl (Italian 3rd Division Serie C, 2019-2020). In fact, it is very important for the team to try to minimize or greatly reduce the incidence of injuries to ensure a better choice of players available to the coach according to the match. Our analysis will try to better understand the importance of creating an adequate postural set up by optimizing the functioning of the muscle kinetic chains, during the pre-training phase. Twenty eigth (n=28) élite football players took part in this study (age 21.4±3.3; body weigth 79.7±3.4 ; heigth 182.4±5.5 ; fat mass 9.2±1.9 ; ), without goalkeepers. In pre-season (4 weeks, from july to august) and during a season (december) the players performed yo yo intermittent recovery test level 2 (IR2), to evaluate aerobic and anaerobic performance before the start of season. At same time the players perfomed jump test (SJ, CMJ, CMJAS, JUMPS 15’’), with Optojump Microgate (Microgate, Bolzano, Italy). Every players has been analyzed with K-GPS Live 50Hz (K-Sport Universal STATS, Montelabbate (PU), Italy) and Polar Team System PRO 2 (Polar Electro, Finland, OY) to recorder maximal heart rate during a intermittent test and official match. Every players has done from July (start preseason) to February (in season), 300 sessions of WTA primitive prevention training program before and after training to preparare muscle chains to daily workout, 244 training during this period. Pre and post training program, performed on a daily basis, highlighted that AJ Fano Calcio 1906 srl, total incidence injury is 3.14/1000h, training incidence injury is 1.34/1000h and match incidence injury is 23.6/1000h, respectively - 23.4% to UEFA data total incidence injury (4.1/1000h), -46.4% to UEFA data training incidence injury (2.5/1000h) and 22.3% to Uefa data match incidence injury (19.3/1000h). Infact, this improvement in match injury (contact and non-contact), probabily due, to difference level of football players: in professional third division there are players that have a reduced coordination and intervention times compared to top level players. This element is clear also in different energy cost (í) from different players level during official matches: first division (21.7±0.7%) vs third division (27±2.5%) (ES=3.05, p<0.05). This event represent energy expenditure during a match: third division has low physical, technical and tactical quality compare first division pro and players have high energy expenditure levels. Probabily our hypothesis on this type of prevention program (primitive WTA) should be used already started youth to prepare muscle chains and improve coordination and movements in future athletes to reduce injuries

Super-resolution in map-making based on a physical instrument model and regularized inversion. Application to SPIRE/Herschel

We investigate super-resolution methods for image reconstruction from data provided by a family of scanning instruments like the Herschel observatory. To do this, we constructed a model of the instrument that faithfully reflects the physical reality, accurately taking the acquisition process into account to explain the data in a reliable manner. The inversion, ie the image reconstruction process, is based on a linear approach resulting from a quadratic regularized criterion and numerical optimization tools. The application concerns the reconstruction of maps for the SPIRE instrument of the Herschel observatory. The numerical evaluation uses simulated and real data to compare the standard tool (coaddition) and the proposed method. The inversion approach is capable to restore spatial frequencies over a bandwidth four times that possible with coaddition and thus to correctly show details invisible on standard maps. The approach is also applied to real data with significant improvement in spatial resolution.Comment: Astronomy & Astrophysic
