description: Questo articolo intende analizzare un aspetto importante ma spesso trascurato della didattica dell’italiano come L2/LS: i segnali discorsivi (SD) nell’interazione orale spontanea. La prima parte dell’articolo riporta i risultati di uno studio sull’acquisizione dei segnali discorsivi da parte di apprendenti ispanofoni in contesto formale. Questi dati, raccolti nell’ambito di una ricerca corpus-based, sono risultati utili per migliorare la didattica di questi importanti meccanismi dell’interazione orale. La seconda parte dell’articolo passa in rassegna i manuali di italiano più usati nelle scuole spagnole che insegnano lingue straniere agli adulti, con particolare riferimento alla dimensione testuale e ai SD in particolare. Come risultato di questa rassegna critica, si propone una selezione delle attività didattiche maggiormente coerenti, da un lato, con un effettivo approccio comunicativo e, dall’altro, con i nostri risultati acquisizionali.

Constructing texts, structuring conversations: didactics of discourse markers as pivotal elements in verbal interaction

This paper aims to shed light on an important yet neglected aspect of Italian in L2/FL teaching: discourse markers in oral interaction. The first part reports the outcomes of Italian DM acquisition by Spanish learners in formal contexts, gathered  from corpus-based research, which can be useful for improving Italian DM teaching and learning. The second part is a review of the most commonly used Italian textbooks in Spanish language schools for adult learners, focusing on the oral textual dimension and specially DM. The result of this review is a selection of the DM learning activities most suited to a communicative approach and our acquisitional findings.

description: We study the low-energy bandstructure of armchair and small-bandgap semiconducting carbon nanotubes with proximity-induced superconducting pairing when a spiral magnetic field creates strong effective spin-orbit interactions from the Zeeman term and a periodic potential from the orbital part. We find that gapless Dirac fermions can be generated by variation of a single parameter. For a semiconducting tube with the field in the same plane, a non-degenerate zero mode at momentum k=0 can be induced, allowing for the generation of topologically protected Majorana fermion end states.

description: Photoinduced biological processes occur via one photon absorption in natural light, which is weak, CW and incoherent, but are often studied in the laboratory using pulsed coherent light. Here we compare the response of a molecule to these two very different sources within a quantized radiation field picture. The latter is shown to induce coherent time evolution in the molecule, whereas the former does not. As a result, the coherent time dependence observed in the laboratory experiments will not be relevant to the natural biological process. Emphasis is placed on resolving confusions regarding this issue that are shown to arise from aspects of quantum measurement and from a lack of appreciation of the proper description of the absorbed photon.

description: In present work, detailed examination of extreme rainfall events (EREs) has been carried out using Weather research and forecasting (WRF) model and remotely sensed observations over the North-West Himalayan region. We have performed high resolutions model simulations and studied ERE’s in association with fine resolution INSAT-3D observation. Remarkable variations noted in the remotely sensed outgoing longwave radiation (OLR) and rainfall in association with model simulations during the formation of cloud burst events may be further utilized for giving an alert over the potential locations affected by the EREs. It is unveiled that the fine scale structure of various physical quantities during the formation of the cloud burst events endures remarkable variations in close agreement with the satellite based observations. Results obtained in the present study show a promising pathway for the study, analysis and now-casting of extremely heavy rainfall events based on model simulations in conjunction with remotely sensed observations.

description: Considering a system composed of two different thermoelectric modules electrically and thermally connected in parallel, we demonstrate that the inhomogeneities of the thermoelectric properties of the materials may cause the appearance of an electrical current, which develops inside the system. We show that this current increases the effective thermal conductance of the whole system. We also discuss the significance of a recent finding concerning a reported new electrothermal effect in inhomogeneous bipolar semiconductors, in light of our results.

description: We examined whether borderline personality features may be differentially associated with reactions to social support strategies involving validation (acknowledging distress as normal) vs. reframing (highlighting opportunities for positive outcomes). After completing self-report measures of their borderline personality features and interpersonal problems, participants rated their reactions to receiving either validation or reframing support (randomly assigned) from a close friend with whom they imagined sharing hypothetical negative experiences. Borderline personality features were associated with less positive responses to reframing than to validation, and a tendency to interpret reframing support as an assertion of dominance. Moderated mediation analyses further showed that associations between borderline features and negative responses to reframing support were specifically explained by hostile-dominant interpersonal problems. Findings highlight the importance of validation to help individuals high in borderline features experience the emotional benefits of social support.

In this works, we introduce new derivatives of 1,4-benzodiazepine-2-ones which are synthesized using michael addition reaction of 7-chloro- 1,3-dihydro-5-phenyl-2H-1,4-benzodiazepine-2-ones with fumaric esters that matches with green chemistry protocols. The structures of all products are confirmed by FT-IR, 1H-NMR, 13C-NMR and MASS spectroscopy. Since the stereochemistry of 1,4-benzo diazepine-2-ones is important, we study the most stable conformer of one of the products as a model for conformational analysis by hyper chem soft ware and semi empirical AM1 program. Also, using the 1H-NMR spectrum, we investigate the produced diastereomers of one of products as a model.

description: Nelle  classi multilingue il docente d’italiano L2  riscontra inevitabili diversità riguardo alla progressione dell’apprendimento. Aldilà della motivazione, fattore certo determinante,  i discenti francesi sembrano agevolati, almeno nella comprensione scritta e orale. Ma le comuni radici romanze si traducono unicamente in un vantaggio? La vicinanza linguistica comporta infatti inevitabili interferenze su più piani, principalmente lessicali (faux-amis) e morfosintattici. In questo articolo vengono elencati i transfer più ricorrenti in una cinquantina di apprendenti francesi di livello A1/A2/B1 e si suggeriscono strategie didattiche per contrastarli.

French learners and italian language: close but not enough

In multilingual classes Italian L2 teachers face inevitable diversities regarding the pace of learning.  Aside from motivation, definitely a motivating factor, French students are advantaged, at least in oral and written comprehension.  But are the common romance roots necessarily an advantage?  The linguistic proximity causes inevitable interference on many levels, especially in terms of lexis (faux.amis) and morfosyntax. The most common transferences are listed in the article, based on 50 French learners at the A1/A2/B1 level and didactic strategies to deal with these problems are suggested.

Discovering the composite Higgs through the decay of a heavy fermion

description: A possible composite nature of the Higgs could be revealed at the early stage of the LHC, by analyzing the channels where the Higgs is produced from the decay of a heavy fermion. The Higgs production from a singly-produced heavy bottom, in particular, proves to be a promising channel. For a value λ=3 of the Higgs coupling to a heavy bottom, for example, we find that, considering a 125 GeV Higgs which decays into a pair of b-quarks, a discovery is possible at the 8 TeV LHC with 30 fb^{-1} if the heavy bottom is lighter than roughly 530 GeV (while an observation is possible for heavy bottom masses up to 650 GeV). Such a relatively light heavy bottom is realistic in composite Higgs models of the type considered and, up to now, experimentally allowed. At \sqrt{s}=14 TeV the LHC sensitivity on the channel increases significantly. With λ=3 a discovery can occur, with 100 fb^{-1}, for heavy bottom masses up to 1040 GeV. In the case the heavy bottom was as light as 500 GeV, the 14 TeV LHC would be sensitive to the measure of the λ coupling in basically the full range λ>1 predicted by the theory.

description: We investigate connections between the continuum and atomistic descriptions of deformable crystals, using certain interesting results from number theory. The energy of a deformed crystal is calculated in the context of a lattice model with general binary interactions in two dimensions. A new bond counting approach is used, which reduces the problem to the lattice point problem of number theory. The main contribution is an explicit formula for the surface energy density as a function of the deformation gradient and boundary normal. The result is valid for a large class of domains, including faceted (polygonal) shapes and regions with piecewise smooth boundaries.

description: In questo breve saggio ci proponiamo di illustrare le peculiarità dell’italiano parlato in Uzbekistan dagli studenti dell’Università delle Lingue Mondiali di Tashkent, dove chi scrive presta servizio come Lettore ministeriale dal gennaio del 2008. Dalle nostre osservazioni si evince come  la L1 e la prima lingua straniera studiata a scuola, l’inglese, possono interferire durante il processo di apprendimento della lingua italiana. I due gruppi linguistici più consistenti all’interno dei corsi di italiano della scrivente sono rappresentati dagli usbechi e dai russi e per questo motivo l’analisi sarà limitata ad essi. Il nostro non vuole essere un mero studio comparativo delle lingue usbeca, russa e italiana ma intende evidenziare le maggiori difficoltà linguistiche che incontrano gli studenti di italiano in Uzbekistan, in particolare nelle prime fasi dell’interlingua, e suggerire alcune strategie per superarle.

Spoken and written italian by uzbek students: an analysis of possible interferences from their native language

 The following brief essay discusses Italian usage by students of the Uzbek State University of World Languages, where the author has been working as Lecturer for the Italian Foreign Office since January 2008. The thesis of this article is that the students’ native language and the first foreign language studied at school, English, interfere with the process of learning Italian. The two largest language groups in the author’s classes are Uzbek und Russian and the analysis is restricted to interference problems from them. It is not an exhaustive comparative study of Uzbek, Russian and Italian, but investigates the main difficulties that Italian learners in Uzbekistan have and suggests some ways to overcome them.

description: In the metacognitive model of psychological disorders, metacognitive strategies and corresponding underlying metacognitive beliefs intensify and maintain emotional distress symptoms. In the current study, our three objectives were to evaluate and replicate the network structure of dysfunctional metacognitions as assessed with the MCQ-30, to examine its stability when adding relevant covariates in the form of metacognitive strategies (worry and rumination) and symptoms (anxiety and depression), and to evaluate how different sets of dysfunctional metacognitions are more or less strongly linked differently to metacognitive strategies and symptoms. A cross-sectional university sample with a mean age of 26 years (N = 440; Males = 156, Females = 283) completed the Metacognitions Questionnaire–30, Penn State Worry Questionnaire, Ruminative Response Scale, and Hopkins Symptom Checklist. Data were analysed using psychological network analysis in R-studio statistical software. The network structure of dysfunctional metacognitions replicated well with item clusters that correspond to clinically meaningful substructures in the metacognitive model. Negative metacognitive beliefs and beliefs about uncontrollability might have more functional significance in the mutual connections between dysfunctional meta-domains as well as the connections with metacognitive strategies and symptoms. For worry and anxiety, negative beliefs about uncontrollability and corresponding danger of worry were more prominently connected in the network structure. For rumination, cognitive self-consciousness was more prominent, whereas for depression, need for control was more prominently connected. Support was found for mutual interdependence between different sets of dysfunctional metacognitive beliefs, that metacognitive beliefs are linked to but separate from metacognitive strategies, and that these may function together in affecting emotional distress symptoms

description: Apprendere una disciplina non significa esclusivamente assimilarne i contenuti, ma anche parlarne la lingua specifica: si tratta di una questione che la presenza sempre maggiore di studenti non madrelingua nella scuola italiana ha reso solo più evidente e riproposto in tutta la sua urgenza. Da recenti indagini, tra i linguaggi disciplinari, quello della storia è risultato essere uno dei più complessi; a partire quindi da un’analisi delle caratteristiche specifiche della lingua della storia (dal lessico alla morfo-sintassi, dall’organizzazione testuale alla tipologia dei concetti della disciplina), il presente intervento si propone di individuare le possibili strategie di semplificazione e di facilitazione didattica, evidenziandone anche gli eventuali limiti o risvolti negativi. L’articolo si propone quindi di riflettere sulla necessità di rinnovare l’insegnamento disciplinare, rivedendo programmi e metodologie didattiche, anche al fine di un’educazione linguistica globale per l’apprendimento delle lingue a scuola.

Teaching and learning history in a multilingual, multicultural class

Studying a subject does not mean merely assimilating the content, but also using  specific language: the ever-increasing presence of non-mothertongue students in Italian schools makes this appear more and more evident and urgent.  Recent surveys regarding different disciplines showed that history was among the most complex areas.  Starting from an analysis of the specific characteristics of the language of history (from the lexis to the morphosyntax, the organization of the texts to the types of disciplinary concepts), this article singles out the possible ways to simplify and facilitate didactics, also highlighting the limits or negative aspects.

The article is a reflection on the necessity to renew the teaching of disciplines, up-dating didactic programs and methods, with the aim of arriving at a global linguistic education for learning languages at school.

description: A (smooth) dynamical system with transformation group $\mathbb{T}^n$ is a triple $(A,\mathbb{T}^n,α)$, consisting of a unital locally convex algebra $A$, the $n$-torus $\mathbb{T}^n$ and a group homomorphism $α:\mathbb{T}^n\rightarrow\Aut(A)$, which induces a (smooth) continuous action of $\mathbb{T}^n$ on $A$. In this paper we present a new, geometrically oriented approach to the noncommutative geometry of principal torus bundles based on such dynamical systems. Our approach is inspired by the classical setting: In fact, after recalling the definition of a trivial noncommutative principal torus bundle, we introduce a convenient (smooth) localization method for noncommutative algebras and say that a dynamical system $(A,\mathbb{T}^n,α)$ is called a noncommutative principal $\mathbb{T}^n$-bundle, if localization leads to a trivial noncommutative principal $\mathbb{T}^n$-bundle. We prove that this approach extends the classical theory of principal torus bundles and present a bunch of (non-trivial) noncommutative examples.

Bayesian evidence for non-zero theta_13 and CP-violation in neutrino oscillations
Creators: name: Bergstrom, Johannes
Publisher: name: arXiv
Year: 2012
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We present the Bayesian method for evaluating the evidence for a non-zero value of the leptonic mixing angle theta_13 and CP-violation in neutrino oscillation experiments. This is an application of the well-established method of Bayesian model selection, of which we give a concise and pedagogical overview. When comparing the hypothesis theta_13 = 0 with hypotheses where theta_13 > 0 using global data but excluding the recent reactor measurements, we obtain only a weak preference for a non-zero theta_13, even though the significance is over 3 sigma. We then add the reactor measurements one by one and show how the evidence for theta_13 > 0 quickly increases. When including the Double Chooz, Daya Bay, and RENO data, the evidence becomes overwhelming with a posterior probability of the hypothesis theta_13 = 0 below 10^-11 . Owing to the small amount of information on the CP-phase delta, very similar evidences are obtained for the CP-conserving and CP-violating hypotheses. Hence, there is, not unexpectedly, neither evidence for nor against leptonic CP-violation. However, when future experiments aiming to search for CP-violation have started taking data, this question will be of great importance and the method described here can be used as an important complement to standard analyses.

description: We consider a model of restricted dimers coupled to two-dimensional causal dynamical triangulations (CDT), where the dimer configurations are restricted in the sense that they do not include dimers in regions of high curvature. It is shown how the model can be solved analytically using bijections with decorated trees. At a negative critical value for the dimer fugacity the model undergoes a phase transition at which the critical exponent associated to the geometry changes. This represents the first account of an analytical study of a matter model with two-dimensional interactions coupled to CDT.

description: Based on random matrix theory, we compute the likelihood of saddles and minima in a class of random potentials that are softly bounded from above and below, as required for the validity of low energy effective theories. Imposing this bound leads to a random mass matrix with non-zero mean of its entries. If the dimensionality of field-space is large, inflation is rare, taking place near a saddle point (if at all), since saddles are more likely than minima or maxima for common values of the potential. Due to the boundedness of the potential, the latter become more ubiquitous for rare low/large values respectively. Based on the observation of a positive cosmological constant, we conclude that the dimensionality of field-space after (and most likely during) inflation has to be low if no anthropic arguments are invoked, since the alternative, encountering a metastable deSitter vacuum by chance, is extremely unlikely.

Self-heating and spontaneous combustion of wood pellets during storage
Creators: name: Guo, Wendi
Publisher: name: University of British Columbia

description: Self-heating of wood pellets is a major concern during long term storage. Internal temperatures rose to 57℃ in 10 days in a wood pellet silo of 21.9 m diameter in Fibreco Inc. (Vancouver, Canada) after pellets (about 20℃) were loaded into the silo. Self-heating could lead to serious accidental fires, causing enormous damage and danger to workers. In this study, the self-heating rate at different temperatures was experimentally determined, and the thermal properties were measured. for wood pellets produced in British Columbia, Canada. The factors such as moisture content, pellet age and environment temperature were investigated and their impacts on the self-heating process were analyzed. Moisture content has a significant effect on effective thermal conductivity and specific heat capacity of packed pellets, but has no effect on the self-heating at the temperature range of 30℃ to 50℃. Pellets age and environment temperature are two major factors impacting the self-heating and off-gassing process. The self-heating rate is significantly increased at higher a temperature and eventually will lead to a thermal runaway when the ambient temperature is high enough. Experimental results show that the critical ambient temperature for thermal runaway decreases as the reactor size increases. The reaction kinetics was studied at both low temperatures (30℃ to 50℃) and high temperatures (100℃ to 200℃) and kinetic parameters were extracted from experimental results and correlations were developed. Based on all measured properties data and kinetics data, a two-dimensional axi-symmetric self-heating model was developed to predict the self-heating process and thermal runaway in large wood pellet silo. The influences of cooling airflow rate, wall insulation, and dimension of the storage container, ambient temperature and wind condition were studied. The results show that air ventilation inside of the silo is a very effective approach for reducing self-heating and preventing thermal runaway at ambient temperatures lower than 330 K. The critical ambient temperature for a 21 m diameter silo can be as low as 36℃ in the absence of air ventilation. The current model can be used to safe guide the design and operation of large industrial wood pellets silos.

description: Αυτή η διατριβή επιδιώκει να συνοψίσει τις προκλήσεις στην παραγωγή πετρελαίου και τους μηχανισμούς που ευθύνονται για τη βλάβη του ταμιευτήρα. Οι δύο κυρίαρχες τεχνικές διέγερσης της γεώτρησης είναι η όξινη διέγερση (acidizing) και η υδραυλική ρωγμάτωση (hydraulic fracturing). Πιο συγκεκριμένα, το πρώτο κεφάλαιο εξετάζει τους συνηθέστερους μηχανισμούς που προκαλούν βλάβη στο ταμιευτήρα, τη προέλευση, καθώς και τις μεθόδους πρόληψής τους. Το δεύτερο κεφάλαιο διερευνά τις κρίσιμες μεταβλητές που χρησιμοποιούνται στη μηχανική παραγωγής για τον υπολογισμό της βλάβης, της ροής των υδρογονανθράκων, της απόδοσης εισροής και της παραγωγικότητας. Το τρίτο κεφάλαιο συνοψίζει τις μεθόδους διέγερσης της γεώτρησης και τους βασικούς παράγοντες που πρέπει να ληφθούν υπόψη κατά την επιλογή μιας τεχνικής διέγερσης. Το τέταρτο κεφάλαιο περιγράφει τις διαδικασίες όξινης διέγερσης, καθώς και τις διαφορές της σε ψαμμίτη και σε ανθρακικά πετρώματα. Το τελευταίο κεφάλαιο καλύπτει αναλυτικότερα την υδραυλική ρωγμάτωση, περιλαμβάνοντας τον τρόπο λειτουργίας της, τις οικονομικές και περιβαλλοντικές παραμέτρους, τα στάδια της διαδικασίας στο πεδίο, την επιλογή ρευστού και στηρικτικού υλικού (proppant), καθώς και την ευαισθησία των διαφόρων μεταβλητών.
description: This dissertation seeks to summarize the challenges in petroleum production and the mechanisms responsible for formation damage. The two prevalent wellbore stimulation techniques are acidizing and hydraulic fracturing. More specifically, the first chapter discusses the most common mechanisms that cause formation damage, as well as their origins and prevention methods. The second chapter investigates the useful variables employed in production engineering for calculating damage, hydrocarbon flow, inflow performance, and productivity. The third chapter summarizes well stimulation treatments and the key factors to consider when selecting a stimulation method. The fourth chapter describes the acidizing treatments as well as the differences between sandstone acidizing and carbonate acidizing. The final chapter covers hydraulic fracturing in further detail, including how it works, economic and environmental considerations, procedure phases on the field, fluid/proppant selection, and variable sensitivities.

description: Das Ankh-Hor Projekt der Ludwig-Maximilians-Universität München (geleitetvonProf.Dr.Budka) ist in Ägypten lokalisiert–genauer in der antiken Nekropole welche zur modernen Stadt Luxor zählt (antiker griechischer Name für die antike ägyptische Stadt: Theben). Diese „thebanische Nekropole“ besteht aus mehreren einzelnen Bestattungsgebieten, zu denen das sogenannte „Asasif“ und das Grab mit der Nummer 414 gehört. Das Projekt umfasst ägyptologische Untersuchungen, Konservierung und die Publikation aller Funde, welche bereits in den 1970ern vom Österreichischem Archäologischen Institut geborgen wurden und bis heute auf der Grabung gelagert werden. Der Sarg der Isetemkheb wurde aufgrund stilistischer Vergleiche in die sogenannte „frühe Ptolemäerzeit“ des pharaonischen Ägyptens datiert, welche in etwa die Zeitspanne von 300 bis 250 v. Chr. umfasst. Das Projekt befindet sich in der Phase der Objekt-Rückgewinnung, d.h. hunderte von vermischten Holzfragmenten (entstanden durch Grabraub und Zerstörung) werden wieder zu zahlreichen Objekten zurücksortiert. Die Autorin wurde 2022 mit der Aufgabe der Konservierungskonzeption und auszugsweisen Umsetzung beauftragt, daher zählte die Untersuchung von Holzfragmenten nicht zu den Aufgaben. Jedoch wurden Zustandsänderungen, welche während der Konservierungsumsetzung wahrgenommen wurden, als „Schnappschüsse“ mit einem Smartphone dokumentiert. Dies kann zu einem späteren Zeitpunkt als Ausgangspunkt für mögliche Untersuchungen dienen – unter anderem auch mit dem Ziel einer virtuellen Rekonstruktion der herstellungszeitlichen Farbigkeit.

description: The octahedron model introduced recently has been implemented onto graphics cards, which permits extremely large scale simulations via binary lattice gases and bit coded algorithms. We confirm scaling behaviour belonging to the 2d Kardar-Parisi-Zhang universality class and find a surface growth exponent: beta=0.2415(15) on 2^17 x 2^17 systems, ruling out beta=1/4 suggested by field theory. The maximum speed-up with respect to a single CPU is 240. The steady state has been analysed by finite size scaling and a growth exponent alpha=0.393(4) is found. Correction to scaling exponents are computed and the power-spectrum density of the steady state is determined. We calculate the universal scaling functions, cumulants and show that the limit distribution can be obtained by the sizes considered. We provide numerical fitting for the small and large tail behaviour of the steady state scaling function of the interface width.
