Perspectivas comparadas en historia reciente del Cono Sur: informes sobre las violaciones de derechos humanos, sanci\uf3n penal y cambios legislativos del siglo XXI
It is possible to find out a chain clarification-punishment in the way how the Southern Cone\u2019s countries of Latin America to reports of human rights violations committed during ring the civil-military dictatorships of the 70s and 80s has followed a criminal sanction. Comparing the cases of Argentina, Chile and Uruguay is possible to individuate stays and differences in a context where cuts and continuities of political hegemony seem key interpretation
Il nuovo volto dell\u2019America latina
A partire dalla fine degli anni \u201890 l\u2019America latina esce da quelli che vengono considerati gli anni del Washington Consensus e dell\u2019ortodossia neoliberale che avevano caratterizzato il ventennio precedente. Una serie di governi di centro-sinistra vengono a caratterizzarsi per la marcata attenzione alle politiche di integrazione continentali e per la ricerca di un\u2019autonomia politica rispetto agli Stati Uniti che, senza diventare mai conflitto aperto, assume spesso toni marcati. Governi come quello brasiliano di Lula da Silva, quello venezuelano di Hugo Ch\ue1vez, il boliviano di Evo Morales, l\u2019argentino di N\ue9stor Kirchner e altri, cambiano completamente il panorama politico continentale riportando in auge il ruolo dello Stato e mettendo l\u2019accento su una rinnovata attenzione per politiche pubbliche di riduzione della povert\ue0 e del disagio sociale.
Il saggio, pubblicato sulla rivista edita dalla rivista del SISDE, Sistema d\u2019Informazione per la Sicurezza Della Repubblica, analizza che valore strutturale \ue8 possibile attribuire al percorso storico dei governi integrazionisti latinoamericani, culminata nel dicembre 2007, nella fondazione del Banco del Sur, su come si sta modificando il ruolo degli Stati Uniti in un cortile di casa dove, per la prima volta dal riflusso dell'impero britannico, e ben pi\uf9 di quanto non avesse ambito a fare l'Unione Sovietica, altri attori, come la Cina, l'India, la stessa Unione Europea ed il commercio Sud-Sud stanno ricavando quote di mercato e politiche sempre pi\uf9 importanti. L\u2019idea dell\u2019autore \ue8 che proprio i processi storici latinoamericani rappresentino la palestra per la costruzione di un mondo multipolare

il volto della morte: le maschere funerarie della sepoltura dei preti morti di Gangi
riassunto — Le mummie moderne e il signifcato recondito della doppia sepoltura nelle culture mediterranee moderne sono da tempo ampiamente dibattuti. In questo lavoro si discute di una particolare “collezione” di corpi di ecclesiastici, mummifcati ed esposti in un comune montano madonita della Sicilia, Gangi. I corpi, principalmente risalenti al XIX secolo, mummifcati per colatura come nella tradizione del tempo e vestiti degli abiti talari, sono esposti nel piano sottostante della Chiesa Madre, in quella che nella tradizione è detta la “fossa dei parrini” (fossa dei preti). Le mummie, a differenza di altri siti siciliani e mediterranei, sono altresì corredate di sonetto commemorativo e di maschera mortuaria realizzata in cera fne. L’interesse precipuo del nostro studio si è rivolto proprio a questa particolare manifestazione complessa della doppia sepoltura, che risiede nella rappresentazione del volto. Il lavoro esprime una disamina del concetto di maschera mortuaria nell’antichità e porta alla conclusione che il luogo, per le sue valenze scenografche e per la sofsticatezza della ritualizzazione dovesse essere stato ideato per l’ostentazione e il consolidamento dell’immagine della Chiesa e del suo potere all’interno della piccola società rurale
Functional polymeric coatings for csi(Tl) scintillators
The handling of inorganic scintillators (e.g., alkali metal halides) can benefit from the availability of polymeric materials able to adhere to their surface. Polymeric materials, such as epoxy resins, can act as protective coatings, as adhesives for photodiodes to be connected with the scintillator surface, and as a matrix for functional fillers to improve the optical properties of scintillators. Here, the optical properties of two epoxy resins (E-30 by Prochima, and Technovit Epox by Heraeus Kulzer) deposited on the surface of a scintillator crystal made of CsI(Tl) were investigated, in order to improve the detection of high-energy radiation. It is found that these resins are capable of adhering to the surface of alkali metal halides. Adhesion, active at the epoxy–CsI(Tl) interface, can be explained on the basis of Coulomb forces acting between the ionic solid surface and an ionic intermediate of synthesis generated during the epoxy setting reaction. Technovit Epox showed higher transparency, and it was also functionalized by embedding white powdered pigments (PTFE or BaSO4) to achieve an optically reflective coating on the scintillator surface
Early Detection of Wild Rocket Tracheofusariosis Using Hyperspectral Image-Based Machine Learning
Fusarium oxysporum f. sp. raphani is responsible for wilting wild rocket (Diplotaxis tenuifolia L. [D.C.]). A machine learning model based on hyperspectral data was constructed to monitor disease progression. Thus, pathogenesis after artificial inoculation was monitored over a 15-day period by symptom assessment, qPCR pathogen quantification, and hyperspectral imaging. The host colonization by a pathogen evolved accordingly with symptoms as confirmed by qPCR. Spectral data showed differences as early as 5-day post infection and 12 hypespectral vegetation indices were selected to follow disease development. The hyperspectral dataset was used to feed the XGBoost machine learning algorithm with the aim of developing a model that discriminates between healthy and infected plants during the time. The multiple cross-prediction strategy of the pixel-level models was able to detect hyperspectral disease profiles with an average accuracy of 0.8. For healthy pixel detection, the mean Precision value was 0.78, the Recall was 0.88, and the F1 Score was 0.82. For infected pixel detection, the average evaluation metrics were Precision: 0.73, Recall: 0.57, and F1 Score: 0.63. Machine learning paves the way for automatic early detection of infected plants, even a few days after infection
Fatal cranial injury in an individual from Messina (Sicily) during the times of the Roman Empire
Forensic and archaeological examinations of human skeletons can provide us with evidence of violence.
In this paper, we present the patterns of two cranial lesions found on an adult male (T173) buried in a
grave in the necropolis ‘Isolato 96’, Messina, Sicily, dating back to the Roman Empire (1st century BC - 1st
century AD). The skull reveals two perimortem traumatic lesions, one produced by a sharp object on the
right parietal bone and the other one on the left parietal bone, presumably the result of a fall. The
interpretation of fracture patterns found in this cranium are an illustration of how forensic approaches
can be applied with great benefit to archaeological specimens.

Atorvastatin combined to interferon to verify the efficacy (ACTIVE) in relapsing-remitting active multiple sclerosis patients: a longitudinal controlled trial of combination therapy.
A large body of evidence suggests that, besides their cholesterol-lowering effect, statins exert anti-inflammatory action. Consequently, statins may have therapeutic potential in immune-mediated disorders such as multiple sclerosis. Our objectives were to determine safety, tolerability and efficacy of low-dose atorvastatin plus high-dose interferon beta-1a in multiple sclerosis patients responding poorly to interferon beta-1a alone. Relapsing–remitting multiple sclerosis patients, aged 18–50 years, with contrast-enhanced lesions or relapses while on therapy with interferon beta-1a 44 mg (three times weekly) for 12 months, were randomized to combination therapy (interferon+atorvastatin 20mg per day; group A) or interferon alone (group B) for 24 months. Patients underwent blood analysis and clinical assessment with the Expanded Disability Status Scale every 3 months, and brain gadolinium-enhanced magnetic resonance imaging at screening, and 12 and 24 months thereafter. Primary outcome measure was contrast-enhanced lesion number. Secondary outcome measures were number of relapses, EDSS variation and safety laboratory data. Forty-five patients were randomized to group A (n 1⁄4 21) or B (n 1⁄4 24). At 24 months, group A had significantly fewer contrast-enhanced lesions versus baseline (p 1⁄4 0.007) and significantly fewer relapses versus the two pre-randomization years (p < 0.001). At survival analysis, the risk for a 1-point EDSS increase was slightly higher in group B than in group A (p 1⁄4 0.053). Low-dose atorvastatin may be beneficial, as add-on therapy, in poor responders to high-dose interferon beta-1a alone
Lamotrigine versus valproic acid as first-line monotherapy in newly diagnosed typical absence seizures: an open-label,randomized, parallel-group study
Purpose: To compare the efficacy of lamotrigine
(LTG) and valproic acid (VPA) in newly diagnosed children and
adolescents with typical absence seizures.
Methods: A randomized, open-label parallel-group design
was used. After undergoing an awake video-EEG recording,
which included one to two trials of 3 min of hyperventilation
and intermittent photic stimulation, eligible patients were randomized
to receive LTG or VPA. LTG was initiated at a daily
dose of 0.5 mg/kg for 2 weeks in two divided doses, followed by
1.0 mg/kg/day for an additional 2 weeks. Thereafter, doses were
increased in 1-mg/kg/day increments every 5 days until seizures
were controlled, intolerable adverse effects occurred, or a maximum
dose of 12 mg/kg/day had been reached. VPA was equally
uptitrated according to clinical response, starting at 10 mg/kg
and increasing by 5 mg/kg/24 h every 3 days, if required, to a
maximum of 30 mg/kg/day in three divided doses. Patients were
seen in the clinic every month for ≤12 months.The primary efficacy
end point at each visit was seizure freedom, defined as lack
of clinically observed seizures since the previous visit and lack
of electroclinical seizures during ambulatory 24-h EEG testing
and a video-EEG session with hyperventilation.
Results: Thirty-eight children (17 boys, 21 girls), aged from 3
to 13 years (mean, 7.5 years), all newly diagnosed with childhood
or juvenile typical absence seizures, were enrolled. After 1 month
of treatment, 10 (52.6%) of 19 children taking VPA and one
(5.3%) of 19 taking LTG were seizure free (p = 0.004). By
the 3-month follow-up, 12 (63.1%) children taking VPA and
seven (36.8%) taking LTG were controlled (p = 0.19). After 12
months, 13 children taking VPA (dose range, 20–30 mg/kg/day;
mean serum level, 76.8 mg/L; range, 51.4–91 mg/L) and 10
taking LTG (dose range, 2–11 mg/kg/day; mean serum level,
8.1 mg/L; range, 1.1–18 mg/L) were seizure free (p=0.51). Side
effects were mostly mild and transient and were recorded in two
(10.6%) children treated with VPA and in six (31.8%) treated
with LTG.
Conclusions: Both VPA and LTG can be efficacious against
absence seizures, although VPA shows a much faster onset of
action, at least in part because of its shorter titration schedule.
KeyWords: Lamotrigine—Valproic acid—Typical absences—
Monotherapy.
Valproic acid (VPA) and ethosuximide (ESM) have
been shown to be equally effective as monotherapy for
typical absence seizures (1,2), and, at present, they are generally
considered first-choice drugs for this seizure type.
VPA controls absences in∼75% of patients, in addition to
being effective against generalized tonic–clonic seizures
(70%) and myoclonic seizures (75%). However, its use
may involve safety risks for postmenarchal women (3).
ESM produces complete control of absences in 70% of
treated patients (4,5), but it is unsuitable as monotherapy
