description: Alla fine del 2021, Angelo Turco non avrebbe potuto immaginare che l’evidenza empirica gli avrebbe offerto un nuovo banco di prova per le riflessioni sul ciclo comunicativo dell’informazione globalitaria già pochi mesi dopo la pubblicazione del suo volume Epimedia. Informazione e comunicazione nello spazio pandemico: sta di fatto che l’egemonismo comunicativo della guerra in corso dal 24 febbraio dell’anno passato ha sostituito repentinamente quello del COVID-19, motivando l’Autore alla stesura del libro Geopolitica, informazione e comunicazione nella guerra russo-ucraina. La guerra, la pace, l’analisi scientifica, i media, sempre nella collana “Studi e ricerche sul territorio” della casa editrice Unicopli.

Οι καταλύτες βαναδίου εμφανίζουν την υψηλότερη ενεργότητα στην αντίδραση της αφυδρογόνωσης του προπανίου παρουσία οξειδωτικού μέσου(οξειγόνου). Μελετήθηκε λοιπόν τόσο η επίδραση του φορέα στους καταλύτες βαναδίου, όσο και η επίδραση του ποσοστού του οξειδίου του βαναδίου που εναποτίθεται στην επιφάνεια του φορέα. Ως βέλτιστος φορέας για τη διασπορά του οξειδίου του βαναδίου βρέθηκε ότι είναι το οεξίδιο του τιτανίου
description: In the present PhD thesis, the oxidative dehydrogenation of propane was investigated and the aim was to develop novel catalytic materials in order to achieve high propylene productivity. The effect of the nature of active metal and of the support was explored. The study was focused on supported vanadia catalysts because they were found to be very active in the oxidative dehydrogenation reaction. Dispersion of vanadia on titania resulted in high propane conversion at relative low temperatures, whereas the selectivity to desired olefin remained at low levels

description: The scope of this doctorate dissertation is the study of the characteristics of residential power distribution networks for power line communications. At first a theoretical methodology is presented for the calculation of the electrical parameters of two-conductor circuits versus frequency. Moreover, specific problems which make some of the calculations theoretically impossible are denoted. In addition, calculations based on the Finite Element Method are conducted for the extraction of the series impedances of cable types commonly used in residential power distribution circuits. Both the cables' third conductor and the presence of the earth are taken into account. Next, a simple model is proposed for the cables of residential power distribution circuits based on the above calculations, as well as on the topology of the circuits. The proposed model is evaluated through measurements conducted in real cable configurations with a network analyzer. Finally, a novel method is proposed for the determination of the topology of residential power line circuits, based on the usage of appropriate neural networks. The theoretical background of the method is analyzed, and applications based on it are presented

description: We examine the duality between type 0 noncritical strings and topological B-model strings, with special emphasis on the flux dependence. The former theory is known to exhibit holomorphic factorisation upto a subtle flux-dependent disc term. We give a precise definition of the B-model dual and propose that it includes both compact and noncompact B-branes. The former give the factorised part of the free energy, while the latter violate holomorphic factorisation and contribute the desired disc term. These observations are generalised to rational radii, for which we derive a nonperturbatively exact result. We also show that our picture extends to a proposed alternative topological-anti-topological picture of the correspondence for type 0 strings.

description: Negli ultimi decenni si è assistito ad una crescita esponenziale della sensibilità nei confronti delle problematiche ambientali e sociali; a ciò ha fatto seguito il proliferare degli studi in tema di Corporate Social Responsibility, di seguito CSR. I primi contributi sul tema però, hanno visto come protagoniste le imprese di grandi dimensioni. Solo di recente è stata avvertita necessità di studiare la tematica facendo specifico riferimento alle imprese di micro, piccole e medie dimensioni. Tuttavia, dall’analisi della letteratura è emersa una carenza di studi aventi ad oggetto i modelli di CSR delle imprese di più piccole dimensioni appartenenti a peculiari settori produttivi. Lo studio si propone di colmare il gap della letteratura attraverso lo sviluppo di un caso studio avente ad oggetto una microimpresa operante nel settore turistico. I risultati dimostrano che il modello di CSR dell’impresa esaminata è influenzato tanto dalle caratteristiche dimensionali dell’organizzazione produttiva analizzata, che dalle specifiche determinanti di settore.

Orthonormal wave functions for periodic fermionic states under an applied magnetic field

description: We report an infinite number of orthonormal wave functions bases for the quantum problem of a free particle in presence of an applied external magnetic field. Each set of orthonormal wave functions (basis) is labeled by an integer $p$, which is the number of magnetic fluxons trapped in the unit cell. These bases are suitable to describe particles whose probability density is periodic and defines a lattice in position space. The present bases of orthonormal wave functions unveils fractional effects since the number of particles in the unit cell is independent of the number of trapped fluxons. For a single particle under $p$ fluxes in the unit cell, and confined to the lowest Landau level, the probability density vanishes in $p$ points, thus each zero is associated to a fraction $1/p$ of the particle. Remarkably the case of $n+1$ filled Landau levels, hence with a total of $N=(n+1)p$ fermions, $n$ being the highest filled Landau level, the density displays an egg-box pattern with $p^2$ maxima (minima) which means that a $(n+1)/p$ fraction of flux is associated to every one of these maxima (minima). We also consider the case of particles interacting through the magnetic field energy created by their own motion and find an attractive interaction among them in case they are confined to the lowest Landau level ($n=0$). The well-known de Haas-van Alphen oscillations are retrieved within the present orthonormal basis of wave functions thus providing evidence of its correctness.

description: We study LHC phenomenology of mirage mediation scenario in which anomaly and modulus contributions to soft SUSY breaking terms are comparable to each other. A Monte Carlo study of mirage mediation, with model parameters $α=1$,$ M_0=500$ GeV, $n_M=1/2$, $n_H=1$ and $\rm{tan}β=10$, is presented. It is shown that masses of supersymmetric particles can be measured in a model independent way, providing information on SUSY breaking sector. In particular, the mass ratio of gluino to the lightest neutralino for the benchmark scenario is determined to be $1.9 \lesssim m_{\tildeg}/m_{\tildeχ_1^0} \lesssim 3.1$, well reproducing theoretical input value of $m_{\tilde g}/m_{\tildeχ_1^0} \simeq 2.5$ which is quite distinctive from the predictions $m_{\tilde g}/m_{\tildeχ_1^0} \gtrsim 6$ of other SUSY scenarios in which gaugino masses are unified at the GUT scale. The model parameters of mirage mediation can be also determined from various kinematic distributions.
Update on the Non-Huntington’s Disease Choreas with Comments on the Current Nomenclature
Creators: name: Walker, Ruth Helen
Publisher: name: Tremor and Other Hyperkinetic Movements
Year: 2012

description: Chorea can be caused by a multitude of etiologies: neurodegenerative, pharmacological, structural, metabolic, and others. In absence of other apparent causes, exclusion of Huntington's disease is often a first step in the diagnostic process. There are a number of neurodegenerative disorders whose genetic etiology has been identified in the past decade. Molecular diagnosis has enabled genetic identification of disorder subtypes which were previously grouped together, such as the neurodegeneration with brain iron accumulation disorders and the neuroacanthocytosis syndromes, as well as identification of phenotypic outliers for recognized disorders. Correct molecular diagnosis is essential for genetic counseling and, hopefully, ultimately genetic therapies. In addition, there has recently been recognition of other disorders which can mimic neurodegenerative disorders, including paraneoplastic and prion disorders. This article focuses upon recent developments in the field but is not intended to provide an exhaustive review of all causes of chorea, which is available elsewhere. I also discuss the nomenclature of these disorders which has become somewhat unwieldy, but may ultimately be refined by association with the causative gene.

description: Planet-planet scattering best explains the eccentricity distribution of extrasolar giant planets. Past literature showed that the orbits of planets evolve due to planet-planet scattering. This work studies the spin evolution of planets in planet-planet scattering in 2-planet systems. Spin can evolve dramatically due to spin-orbit coupling made possible by the evolving spin and orbital precession during the planet-planet scattering phase. The main source of torque to planet spin is the stellar torque, and the total planet-plane torque contribution is negligible. As a consequence of the evolution of the spin, planets can end up with significant obliquity (the angle between a planet's own orbit normal and spin axis) like planets in our Solar System.

description: The well-known reflection coupling gives a maximal coupling of two one-dimensional Brownian motions with different starting points. Nevertheless, the reflection coupling does not generalize to more than two Brownian motions. In this paper, we construct a coupling of all Brownian motions with all possible starting points (i.e., a grand coupling), such that the coupling for any pair of the coupled processes is close to being maximal, that is, the distribution of the coupling time of the pair approaches that of the maximal coupling as the time tends to $0$ or $\infty$, and the coupling time of the pair is always within a multiplicative factor $2e^{2}$ from the maximal one. We also show that a grand coupling that is pairwise exactly maximal does not exist.

description: Context. Radiation-driven mass loss is key to our understanding of massive-star evolution. However, for low-luminosity O-type stars there are big discrepancies between theoretically predicted and empirically derived mass-loss rates (called the weak-wind problem). Aims. We compute radiation-line-driven wind models of a typical weak-wind star to determine its temperature structure and the corresponding impact on ultra-violet (UV) line formation. Methods. We carried out hydrodynamic simulations of the line-deshadowing instability (LDI) for a weak-wind star in the Galaxy. Subsequently, we used this LDI model as input in a short-characteristics radiative transfer code to compute synthetic UV line profiles. Results. We find that the line-driven weak wind is significantly shock heated to high temperatures and is unable to cool down effciently. This results in a complex temperature structure where more than half of the wind volume has temperatures significantly higher than the stellar effective temperature. Therefore, a substantial portion of the weak wind will be more ionised, resulting in a reduction of the UV line opacity and therefore in weaker line profiles for a given mass-loss rate. Quantifying this, we find that weak-wind mass-loss rates derived from unsaturated UV lines could be underestimated by a factor of between 10 and 100 if the high-temperature gas is not properly taken into account in the spectroscopic analysis. This offers a tentative basic explanation for the weak-wind problem: line-driven weak winds are not really weaker than theoretically expected, but rather a large portion of their wind volume is much hotter than the stellar effective temperature.

description: This thesis, introduces the context of sustainability in the field of irrigated agriculture and presents the application of the economic theory to water resources. Loudias river basin is selected as the reference area of the presented work. This area is well described and spatial analysed. A system of sustainable indicators is then developed aiming to provide sustainability into agricultural decision-making and into water resources management. In addition, the value of irrigation water is estimated as an intermediate "good". Multicriteria analysis is also applied in order to a)derive the irrigation water demand function (by means of two models of multi-attribute utility theory), and b0find the best allocation of land and water resources to assess a number of policy scenarios and to select a group pf best alternatives in terms of sustainability

description: «Questo non è un libro di storia», lo mettono subito in chiaro i due curatori del volume, sin dall’introduzione. Una puntualizzazione, quella di Edoardo Boria e di Matteo Marconi, né banale né superflua e che indirizza il lettore, nel breve spazio di un titolo o poco più, verso la dimensione che hanno inteso dare a quest’opera. Così anche le contraddizioni che si potrebbero scorgere tra il titolo del volume e i numerosi contributi inseriti al suo interno diventano solo apparenti, e non spostano l’attenzione da quello che è l’obiettivo ultimo di questo libro. Guardando alla letteratura nazionale di settore, emerge immediatamente come non vi siano precedenti analoghi, tali, da potere procedere ad eventuali condotte bibliografiche comparative, elemento che di per sé rende già innovativa, quasi pionieristica, l’azione collettanea posta in essere dai due studiosi della Sapienza.

Movements Mimicking Myoclonus Associated with Spinal Cord Pathology: Is this a “Pure Motor Restless Legs Syndrome”?

Year: 2012

description: Background: The neuroanatomic substrate of restless legs syndrome (RLS) is poorly understood, and the diagnosis is clinically made based upon subjective sensory symptoms, although a motor component is usually present. Case Report: We report two cases of elderly patients with spinal pathology who were referred by neurologists for myoclonus. Both had semi-rhythmic leg movements that partially improved while standing, but denied any urge to move. These movements improved dramatically with pramipexole, a dopamine agonist used for RLS. Discussion: We propose that this “myoclonus” is actually the isolated stereotypic motor component of RLS.

Gamow-Teller sum rule in relativistic nuclear models

Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: Relativistic corrections are investigated to the Gamow-Teller(GT) sum rule with respect to the difference between the $β_-$ and $β_+$ transition strengths in nuclei. Since the sum rule requires the complete set of the nuclear states, the relativistic corrections come from the anti-nucleon degrees of freedom. In the relativistic mean field approximation, the total GT strengths carried by the nucleon sector is quenched by about 12% in nuclear matter, while by about 8% in finite nuclei, compared to the sum rule value. The coupling between the particle-hole states with the nucleon-antinucleon states is also discussed with the relativistic random phase approximation, where the divergence of the response function is renormalized with use of the counter terms in the Lagrangian. It is shown that the approximation to neglect the divergence, like the no-sea approximation extensively used so far, is unphysical, from the sum-rule point of view.

Introduzione allo studio degli ambienti umani a cura di Marco Maggioli (Mimesis, 2019) con i due libri qui recensiti si offre ai ricercatori la possibilità di accedere a tutte le fasi del ragionamento del geografo Augustin Berque, nel suo intento di dimostrare come la Geografia ricopra un posto di rilievo all’interno del dibattito sulle sfide dell’Antropocene. Un dibattito su cui, in Francia – ma questo avviene in tutto il Mondo – filosofi, ambientalisti, antropologi, geografi si stanno confrontando da alcuni anni, riflettendo sulle cause del riscaldamento climatico e sull’inquinamento ambientale. Alcuni imputano la responsabilità di tali eventi alla società industriale occidentale e/o al sistema capitalistico che la regge e riconoscono che la sfida, epocale, prima di essere affrontata deve essere padroneggiata intellettualmente. Tra questi, ancorandosi all’ipotesi Gaia proposta qualche decennio fa dal biofisico James Lovelock, vale a dire un pianeta autoregolante messo in crisi dall’attività umana, Michel Serre, Bruno Latour e altri individuano nel pensiero moderno - nato dopo la rivoluzione copernicana – la distinzione tra cultura e scienza che pongono all’origine della contrapposizione tra l’uomo e la natura.

description: The formation and destabilisation of viscoelastic filaments are of importance in many industrial and biological processes. Filament instabilities have been observed for viscoelastic fluids but recently also for soft elastic solids. In this work, we address the central question how to connect the dynamical behavior of viscoelastic liquids to that of soft elastic solids. We take advantage of a biopolymer material whose viscoelastic properties can be tuned over a very large range by its pH, and study the destabilization and ensuing instabilities in uniaxial extensional deformation. In agreement with very recent theory, we find that the interface shapes dictated by the instabilities converge to an identical similarity solution for low-viscosity viscoelastic fluids and highly elastic gels. We thereby bridge the gap between very fluid and strongly elastic materials. In addition, we provide direct evidence that at late times an additional filament instability occurs due to a dynamical phase separation.

description: Background: Cervical dystonia (CD) is characterized by sustained, involuntary contraction of head and neck muscles. Botulinum toxin injections are established as safe and effective, but unfortunately 15–25% of patients fail to respond. The aim of this study was to examine whether multichannel electromyogaphic mapping improved outcomes in a cohort of antibody-negative onabotulinumtoxinA non-responders by more precisely identifying which muscles were involved in the dystonia. Methods: Patients with cervical dystonia who had “failed chemodenervation therapy” administered by an outside provider were enrolled in a single-blind, randomized, crossover design study. Patients received either a multichannel electromyographic mapping study prior to the first botulinum toxin injection, which was followed by use of only a single-lead injection 16 weeks later (injected by an alternate and blinded movement disorders specialist) or vice versa. The primary outcome measure was change in total Toronto Western Spasmodic Torticollis Rating Scale score 4 weeks after each injection compared with each pre-injection baseline score. Results: Nine subjects completed this study. Mean percentage improvement in Total Toronto Western Spasmodic Torticollis Rating Scale was 23.5% using multichannel electromyography compared with 9% using the single-channel technique (p = 0.11). Discussion: This pilot study suggests that multichannel electromyographic mapping may result in improved efficacy in the treatment of antibody-negative onabotulinumtoxinA refractory CD.

description: FM-index is an efficient data structure for string search and is widely used in next-generation sequencing (NGS) applications such as sequence alignment and de novo assembly. Recently, FM-indexing is even performed down to the read level, raising a demand of an efficient algorithm for FM-index construction. In this work, we propose a hardware-compatible Self-Aided Incremental Indexing (SAII) algorithm and its hardware architecture. This novel algorithm builds FM-index with no memory overhead, and the hardware system for realizing the algorithm can be very compact. Parallel architecture and a special prefetch controller is designed to enhance computational efficiency. An SAII-based FM-index constructor is implemented on an Altera Stratix V FPGA board. The presented constructor can support DNA sequences of sizes up to 131,072-bp, which is enough for small-scale references and reads obtained from current major platforms. Because the proposed constructor needs very few hardware resource, it can be easily integrated into different hardware accelerators designed for FM-index-based applications.

description: Plasmonics is based on surface plasmon polariton (SPP) modes which can be laterally confined below the diffraction limit, thereby enabling ultracompact optical components. In order to exploit this potential, the fundamental bottleneck of poor light-SPP coupling must be overcome. In established SPP sources (using prism, grating} or nanodefect coupling) incident light is a source of noise for the SPP, unless the illumination occurs away from the region of interest, increasing the system size and weakening the SPP intensity. Back-side illumination of subwavelength apertures in optically thick metal films eliminates this problem but does not ensure a unique propagation direction for the SPP. We propose a novel back-side slit-illumination method based on drilling a periodic array of indentations at one side of the slit. We demonstrate that the SPP running in the array direction can be suppressed, and the one propagating in the opposite direction enhanced, providing localized unidirectional SPP launching.

description: Currently, national economies devote a great deal of attention to resource efficiency. In this regard, gender equality represents a key factor for unlocking the economic potential of nation states and for leveraging economic growth. Gender equality is not only about the protection of human rights, it is also about economic efficiency and economic development. Many economists and scientists do not pay any attention to these aspects, but still there are some of them who studied this problem and whose researches fairly proved crucial role of gender dimension for business development in the spheres where human resource and their efficiency do matter. The paper analyses data on women representation on top management and compares it with economic performance. The reasons and factors that impede or support women promotion are revealed and analysed. The paper concludes that other social factors - that are inseparable part of high level of human development level, and constitute social and cultural environment of the country, - are significantly influencing the gender equality in terms of economic performance. The paper emphasise the importance of relevant legislation to promote women, and by the desk review and data analysis methods comes to the conclusion that special laws if they do not contain some measures of penalties to improve gender balance (at any level) have limited results and just facilitate and promote but do not ensure equality of women and men representation at any level.

The struggle for inclusion : aboriginal constitutional discourse in the 1970s and 1980s
Creators: name: Wherrett, Barbara Jill
Publisher: name: University of British Columbia
Year: 2011

description: Over the past two decades, aboriginal peoples in Canada have become involved in the process of constitutional revision. As they became engaged in constitutional debates, aboriginal peoples developed a discourse that centred on historic rights, past injustices, and differences from the broader Canadian community. New terms and concepts which described these identities were introduced into constitutional language. An analysis of the testimony of the national aboriginal organizations before Special Joint Committees on the Constitution and the transcripts of the First Ministers' Conferences on Aboriginal Constitutional Matters reveals how aboriginal peoples attempted to reshape the political world through the Constitution. Aboriginal discourse has highlighted the role of the Canadian Constitution as an emblem of status and inclusion in Canadian society. Aboriginal peoples have sought recognition in the Constitution as a way to improve their status and gain symbolic admission into the Canadian state. However, they have sought inclusion according to their own narratives of their history, identity, and aspirations. These separate identities have been reflected in the words they have chosen to describe themselves and their relationship to the Canadian state. Aboriginal constitutional language has served to develop aboriginal identities and alter the terms of Canadian constitutional discourse. The discourse reveals some of the problems posed by aboriginal use of terms such as nation, sovereignty and rights, both for aboriginal and Canadian political leaders. Ultimately, the discourse poses new challenges to concepts of shared Canadian citizenship and identity.

description: Il saggio a cura di Marika Fior, Agim Kërçuku, Cristiana Mattioli, Gloria Pessiana è espressione del progetto «Fragilità Territoriali» (FT) del Dipartimento di Eccellenza DAStU del Politecnico di Milano. Lo sforzo compiuto dai curatori ha il merito di intrecciare prospettive di ricerca individuali dei singoli contributori restituendo un quadro che dà idea della pluralità delle fragilità dei territori della produzione, tema sul quale si incardinano i contributi del libro. Le diverse anime del sistema produttivo italiano rendono infatti complesso il tentativo di tracciare una traiettoria univoca delle trasformazioni che sta vivendo il mondo imprenditoriale e industriale in Italia negli ultimi decenni. L’analisi degli autori parte proprio dall’individuazione di alcuni temi comuni che attraversano i singoli luoghi, affrontati prima con visioni più generali e categorizzanti, e poi, in seconda istanza, con sguardi più ravvicinati, mettendo in dialogo le varie prospettive di ricerca.

description: La Scienza della Complessità apre allo studio della realtà profonda degli organismi viventi che interagiscono fra loro in una struttura che è stata definita “rete della vita” che comporta la necessità di accedere agli aspetti archetipici che la costituiscono e che ne rappresentano il potenziale informativo-organizzativo. Lo scopo di questo lavoro è di indagare la dimensione dell’informazione nei suoi diversi gradi di complessità, distinguendo l’informazione, che l’essere umano percepisce in forma di “segno”, dall’in-formazione ossia “ciò che dà forma”, una connessione sottile e comune a tutte le forme viventi e non viventi. Leggere la realtà in termini olonici significa indagare le corrispondenze con il Tutto e intuire proprietà emergenti che non si presentano immediatamente accessibili alla coscienza. Quando dalla lettura olonica si passa alla lettura simbolica, per il fatto che il simbolo unisce nella propria struttura dinamica una parte consapevole e una parte inconscia, il simbolo mantiene in sé una logica informativa più ampia di quella dell’olone. Pertanto, l’applicazione del simbolo a livello aziendale consiste nella capacità di valorizzare gli “asset intangibili” e di integrarli con il “corpo visibile” dell’azienda potendone cogliere nuove possibilità e concrete vie di realizzazione.

description: Background: Population-based epidemiological studies of essential and other tremors have need of a rapid yet accurate means to assess tremor, especially mild tremors. Handwriting is often affected by tremor, and a hand-drawn spiral can provide investigators with objective rather than self-reported data. We present a semi-quantitative, ordinal scale to rate hand-drawn spirals. The scale, which includes values for mild tremor, is accompanied by photographic examples of spirals of each rating, providing a visual template for guidance. Methods: This study, conducted within the framework of a population-based epidemiological study of 5,000 individuals aged 60 and older in Shanghai, asked enrollees to draw an Archimedes spiral with each hand. Spirals were rated using an ordinal scale (0, 0.5, 1, 1.5, 2, and 3). Three raters rated an initial set of 548 spirals. Four raters rated a subsequent set of 200 spirals using a visual template for guidance. Results: Initial agreement (548 spirals) was good (r values ranged from 0.49 to 0.62, all p<0.001). Subsequent agreement (200 spirals and using visual template) improved (r values ranged from 0.67 to –0.91, all p<0.001). Discussion: This tool will be useful to researchers who are attempting to rapidly assess action tremor in their field surveys.

description: The transverse mass spectra of K0s, Lambda, Xi and Omega particles produced in Pb-Pb collisions at 40 A GeV/c have been studied for a sample of events corresponding to the most central 53% of the inelastic Pb-Pb cross-section. We analyze the distributions in the framework of a parameterized model inspired by hydrodynamics. The dependence of the freeze-out parameters on particle species and event centrality is discussed and comparisons with results at higher energy are shown.

description: Για το βιβλίο Α' Εσδρας έχουν διατυπωθεί κατά καιρούς διαφορετικές θέσεις όσον αφορά τη σύνθεσή του, τη σχέση του με τα πρωτοκανονικά βιβλία και την αξία του για την ανασύνθεση του ιστορικού έργου του χρονικογράφου. Από τη δική μας διαπραγμάτευση του θέματος προέκυψε ότι δεν είναι τυχαίο απόσπασμα από το ιστορικό έργο του χρονικογράφου, ούτε είναι η ιστορία των σωματοφυλάκων ο μοναδικός λόγος ύπαρξης του βιβλίου. Είναι αυτοτελές, δευτερογενές έργο, ακέραιο μόνο ως προς την αρχή, που δημιουργήθηκε περί το 200 π.χ. για την προβολή συγκεκριμένων θέσεων, τις οποίες περιγράφουμε αναλυτικά στην εργασία μας. Δεν είναι απλή συνένωση αποσπασμάτων από βιβλικές πηγές, αλλά σύνθετο έργο, δομημένο με περίσκεψη. Είναι συμπίλημα, επειδή προήλθε από την ένωση τμημάτων διαφορετικών βιβλίων, αλλά και απόσπασμα, επειδή κάποια χρονική στιγμή χάθηκε το τέλος του, το οποίο συνεχίζονταν πιθανότητα μέχρι το Νεεμ. 10:40 (Β' Εσδ. 20:40). Ο συγγραφέας τροποποίησε τις πηγές του και πρόσθεσε εξωβιβλικό υλικό με αποτέλεσμα χρονολογική ασυνέπεια και αντιφάσεις, για τις οποίες αδιαφόρησε ο μεταφραστής, αφού κύριο μέλημά του ήταν να παρουσιάσει συγκεκριμένες ηθικές και θρησκευτικές ιδέες παρά να καταγράψει τα ιστορικά γεγονότα της περιόδου με τη χρονολογική τους τάξη
description: From time to time different aspects have been formulated concerning the compsition of book A' Esdras, its relation to the first canonical books and its valor in the recomposition of the chronicler's historic work. Our treatment of the subject revealed that it is not about an ordinary passage from the chronicler's historic work, nor the history of bodyguards is the only reason of existence of the book. It is an integral, secondary work, constituting an undivided whole only as far as the beggining is concerned, created around 200 b.C. to promote specific positions that we analytically describe in our work. It is not simple joining of passages from Bible sources, but a complex work, structured with prudence. It is an awkward synthesis, because it derive by joining parts of different books, but also a passage, because some time in the past the end of the book that probably continued till Neem. 10:40(B' Esdr.20:40) had been lost. The author modified its sources and added an extra-biblical material rsulting to a chronological inconsistency and contradictions during descriptions of facts, which the translator ignored since his main concern was to present specific moral and religious ideas, than register historic facts of this period in chronological order
Toponimi o odonimi? Aspetti critici e considerazioni metodologiche di una terra di confine

description: È noto in letteratura che gli odonimi sono un sottoinsieme dei toponimi e si riferiscono esclusivamente ai nomi delle strade. Come tutte le categorie di toponimi, questi servono a trasmettere la posizione di un luogo nel linguagio verbale, rimandando all’elemento geografico o dominante cui si riferisce e di conseguenza alla sua posizione. Per questo motivo esiste una naturale corrispondenza tra tipi di toponimi e segni geografici. Se ci si riferisce ad un fiume ci si aspetta una linea su una carta geografica o eventualmente un poligono di forma allungata; mentre se si tratta di una città sarebbe naturale attendersi un poligono che identifichi il centro abitato o il confine amminitrativo, per quanto spesso ritroviamo dei punti ad indicare la posizione di un’etichetta su una mappa.

description: Background: Orthostatic tremor (OT) is a disabling movement disorder manifested by postural and gait disturbance. Primarily a condition of elderly people, it can be progressive in up to 15% of patients. The primary treatments are medications that are often ineffective. Case Report: A 75-year-old male presented with a 10-year history of progressive and disabling OT. He had tried various medications without significant benefits. He underwent bilateral thalamic Vim deep brain stimulation (DBS). At 30-month follow-up, he has had continued significant improvement of his OT. Discussion: Bilateral thalamic DBS may be a viable option for medically refractory OT.
