description: Secular variations of the geomagnetic field have been measured with a continuously improving accuracy during the last few hundred years, culminating nowadays with satellite data. It is however well known that the dynamics of the magnetic field is linked to that of the velocity field in the core and any attempt to model secular variations will involve a coupled dynamical system for magnetic field and core velocity. Unfortunately, there is no direct observation of the velocity. Independently of the exact nature of the above-mentioned coupled system -- some version being currently under construction -- the question is debated in this paper whether good knowledge of the magnetic field can be translated into good knowledge of core dynamics. Furthermore, what will be the impact of the most recent and precise geomagnetic data on our knowledge of the geomagnetic field of the past and future? These questions are cast into the language of variational data assimilation, while the dynamical system considered in this paper consists in a set of two oversimplified one-dimensional equations for magnetic and velocity fields. This toy model retains important features inherited from the induction and Navier-Stokes equations: non-linear magnetic and momentum terms are present and its linear response to small disturbances contains Alfvén waves. It is concluded that variational data assimilation is indeed appropriate in principle, even though the velocity field remains hidden at all times; it allows us to recover the entire evolution of both fields from partial and irregularly distributed information on the magnetic field. This work constitutes a first step on the way toward the reassimilation of historical geomagnetic data and geomagnetic forecast.

description: (Shortened) We show by example how the uncoding of Gamma-Ray Bursts (GRBs) offers unprecedented possibilities to foster new knowledge in fundamental physics and in astrophysics. After recalling some of the classic work on vacuum polarization in uniform electric fields by Klein, Sauter, Heisenberg, Euler and Schwinger, we summarize some of the efforts to observe these effects in heavy ions and high energy ion collisions. We then turn to the theory of vacuum polarization around a Kerr-Newman black hole, leading to the extraction of the blackholic energy, to the concept of dyadosphere and dyadotorus, and to the creation of an electron-positron-photon plasma. We then present a new theoretical approach encompassing the physics of neutron stars and heavy nuclei. It is shown that configurations of nuclear matter in bulk with global charge neutrality can exist on macroscopic scales and with electric fields close to the critical value near their surfaces. These configurations may represent an initial condition for the process of gravitational collapse, leading to the creation of an electron-positron-photon plasma: the basic self-accelerating system explaining both the energetics and the high energy Lorentz factor observed in GRBs. We then turn to recall the two basic interpretational paradigms of our GRB model. [...] We then turn to the special role of the baryon loading in discriminating between "genuine" short and long or "fake" short GRBs [...] We finally turn to the GRB-Supernova Time Sequence (GSTS) paradigm: the concept of induced gravitational collapse. [...] We then present some general conclusions.

description: aims: We determine the solar abundance of phosphorus using co5bold 3D hydrodynamic model atmospheres. method: High resolution, high signal-to-noise solar spectra of the PI lines of Multiplet 1 at 1051-1068 nm are compared to line formation computations performed on a co5bold solar model atmosphere. results: We find A(P)=5.46+- 0.04, in good agreement with previous analysis based on 1D model atmospheres, due to the fact that the PI lines of Mult. 1 are little affected by 3D effects. We cannot confirm an earlier claim by other authors of a downward revision of the solar P abundance by 0.1 dex employing a 3D model atmosphere. Concerning other stars, we found modest (<0.1 dex) 3D abundance corrections for P among four F dwarf model atmospheres of different metallicity, being largest at lowest metallicity. conclusions: We conclude that 3D abundance corrections are generally rather small for the PI lines studied in this work. They are marginally relevant for metal-poor stars, but may be neglected in the Sun.

description: We investigate the nature (Dirac vs. Majorana) and size of left-handed neutrino masses in a supersymmetric five-dimensional model compactified in the interval [0,πR], where quarks and leptons are localized on the boundaries while the gauge and Higgs sectors propagate in the bulk of the fifth dimension. Supersymmetry is broken by Scherk-Schwarz boundary conditions and electroweak breaking proceeds through radiative corrections. Right-handed neutrinos propagate in the bulk and have a general five-dimensional mass M, which localizes the zero modes towards one of the boundaries, and arbitrary boundary terms. We have found that for generic boundary terms left-handed neutrinos have Majorana masses. However for specific boundary configurations left-handed neutrinos are Dirac fermions as the theory possesses a conserved global U(1) symmetry which prevents violation of lepton number. The size of neutrino masses depends on the localization of the zero-modes of right-handed neutrinos and/or the size of the five-dimensional neutrino Yukawa couplings. Left-handed neutrinos in the sub-eV range require either MR~10 or Yukawa couplings ~10^{-3}R, which make the five-dimensional theory perturbative up to its natural cutoff.

description: For nearly 40 years, surface plasmon resonance (SPR) analysis has been used to better understand the binding interaction strength between surface immobilized bioreceptors and the analytes of interest. The advantage of surface plasmon resonance, over other affinity sensing approaches such as Western blots and ELISAs approaches, resides in its possibility to reveal binding kinetics in a label-free manner. The concept of surface plasmon resonance has in addition been widely employed for the development of biosensors capitalizing on its direct assay format, short response times, simple sample treatments along with multiplexed sensing possibilities. To this must be added the possibility to reach high sensitivity due to the capability of surface plasmon resonance to detect very small changes in refractive index at the sensing interfaces in particular for analytes of larger size such as cells (e.g., bacteria), proteins, peptides and oligonucleotides. Challenges inherent to all affinity approaches call for further research and include non-specific surface binding events, mass transportation restrictions, steric hindrance, and the risk of data misinterpretation in case of lack of selective analyte binding. This opinion article is devoted to outlining the different approaches proposed to address these challenges by e.g., coupling with fluorescence read out, electrochemical sensing, mass spectroscopy analysis and more recently to integrate lateral flow concepts into surface plasmon resonance. Other plasmonic methods such as localized surface plasmon resonance (LSPR), surface enhanced Raman spectroscopy (SERS) will not be considered in detail, as such techniques have nowadays their own standing.

description: Rotating deformed neutron stars are important potential sources for groundbased gravitational-wave interferometers such as LIGO, GE0600 and VIRGO. One mechanism that may lead to significant non-asymmetries is the internal magnetic field. It is well known that a magnetic star will not be spherical and, if the magnetic axis is not aligned with the spin axis, the deformation will lead to the emission of gravitational waves. The aim of this paper is to develop a formalism that would allow us to model magnetically deformed stars, using both realistic equations of state and field configurations. As a first step, we consider a set of simplified model problems. Focusing on dipolar fields, we determine the internal magnetic field which is consistent with a given neutron star model. We then calculate the associated deformation. We conclude by discussing the relevance of our results for current gravitational-wave detectors and future prospects.

Le nuove traiettorie geografiche dell’industria farmaceutica globale

description: New geographical trends in the global pharmaceutical industry
The article aims to outline the main trends in global pharmaceutical industry, currently affected by relevant changes, especially related to patent expirations and to the decline of R&D productivity. In the current scenario, US and Europe still have a strong leadership, both from the market and from the innovative capacity point of view. The new dynamics of the industry reveal, however, a new geography in the production, investment and consumption of drugs. Population growth and better economic conditions create a strong demand for healthcare in emerging economies, while in developed countries the demand remains weaker, reflecting cost containment policies. Shift in demand leads to a global redistribution of production capacity and an increase in competition among the advanced economies to consolidate and attract investments. New prospects are now opening for Big Pharma, which will have to face the competition of companies from China, India, Korea, Brazil. Innovation will be essential to compete. In this sense, locating R&D centers in the new global hotspots of innovation will certainly be a key factor for success.

Les nouvelles trajectoires géographiques de l’industrie pharmaceutique
mondiale
L’article analyse les dynamiques principales de l’industrie pharmaceutique mondiale, actuellement impliquée dans une série de changements importants, en particulier liées aux échéances de brevets et à la baisse de la productivité du secteur R&D. Dans le scénario actuel, les Etats-Unis et l’Europe exercent encore un leadership fort, tant du point de vue de la capacité d’innovation que du marché. L’étude des nouvelles dynamiques de l’industrie, cependant, révèle une nouvelle géographie de la production, des investissements et de la consommation de drogues. La croissance démographique et l’amélioration des conditions économiques font croître la demande de santé dans les économies émergentes, tandis que dans les pays développés cette demande est plus lente, reflétant les politiques de maîtrise des coûts. Le déplacement de la demande conduit à une redistribution globale des capacités de production et une augmentation de la concurrence entre les économies avancées pour consolider et attirer les investissements.
De nouvelles perspectives s’ouvrent pour les Big Pharma, qui devraient se préparer à faire face à la concurrence des entreprises de la Chine, l’Inde, la Corée, le Brésil. Le match le plus important sera joué principalement sur le front de l’innovation. En ce sens, localiser leurs centres de R&D dans le nouveaux hotspots mondiales de l’innovation sera certainement un facteur clé.

description: La ricerca tende ad offrire un ampio quadro relativo all’affermazione del principio di leale collaborazione nell’esperienza regionale italiana. Il lavoro è strutturato in tre capitoli. Il primo approfondisce i caratteri dell’originario modello di regionalismo delineato dalla Costituzione repubblicana del 1948 e le dinamiche che hanno finito per caratterizzarlo, nelle sue estrinsecazioni materiali, in senso cooperativo. Nel secondo capitolo si analizzano, più specificamente, i passaggi – soprattutto quelli giurisprudenziali – che hanno portato ad emersione il principio di leale collaborazione e ne hanno determinato i caratteri e gli ambiti di operatività. Il capitolo conclusivo è invece dedicato all’impatto che la riforma del Titolo V, Parte II, della Costituzione - realizzata con la legge costituzionale n. 3 del 2001 - ha avuto sulle relazioni tra diversi livelli territoriali di governo e alla nuova portata che, nel mutato contesto normativo,  ha assunto il principio di leale collaborazione.

Our OPs are derived by folding ab initio nuclear densities with a nucleon-nucleon NN t matrix computed with a consistent chiral interaction. The results of our OPs are in good agreement with the experimental data. Recent achievements of our work are reviewed in this contribution.

description: At the boundary between ontology of geography and border studies
The aim of these pages is to analyze how the notion of boundary has been conceived by contemporary ontologists of geography, outlining the possible advantages of a mutual interaction between ontology and border studies. Firstly, the article shows the most important ontological taxonomies of geographical boundaries, highlighting their main similarities. Secondly, it discusses the relation between cultural elements and geographical boundaries, which represents a fundamental premise of border studies and a potential constituent of ontological categorizations. Thirdly, Epstein’s philosophical distinction between metaphysical grounding and anchoring is considered a metaphor for the different conceptual presuppositions of ontology of geography and border studies. Finally, the distinction between anchoring and grounding helps sketching a possible strategy for integrating the ontological debate within the interdisciplinary perspectives of border studies.

L’objectif de cet article est d’analyser comment la notion de frontière a été conçue par l’ontologie géographique contemporaine, en décrivant des possibles avantages d’une interaction mutuelle entre l’ontologie et les border studies. Premièrement, nous montrerons la plus importante taxonomie ontologique des frontières géographiques, en soulignant les ressemblances principales. Deuxièmement, nous examinerons la relation
entre les éléments culturels et les frontières géographiques, qui est une prémisse fondamentale pour les border studies et une partie potentielle des catégories ontologiques.
Troisièmement, nous utiliserons la distinction philosophique de Brian Epstein entre grounding et anchoring comme une métaphore pour montrer les conditions conceptuelles différentes de l’ontologie géographiques et des border studies. Enfin, nous nous referons encore à la distinction entre grounding et anchoring pour esquisser une stratégie possible pour intégrer le débat ontologique au sein des perspectives interdisciplinaires des border studies.

description: This study investigates the adoption of green technologies by businesses to enhance sustainability and reduce their environmental impact. The objective was to identify the key challenges and benefits associated with green technology integration. A mixed-method approach was used, combining a survey of 150 Fortune 500 executives and qualitative interviews with sustainability officers. Results showed that 62% of companies had adopted at least one green technology, with major barriers including high upfront costs (45%) and regulatory inconsistencies (30%). However, companies that integrated green technologies reported energy savings of up to 25%. The study concludes that while challenges remain, businesses that invest in sustainability are well-positioned for future growth.

Prime indagini sull’allevamento di Psetta maxima in prototipi di gabbia sommergibili

Publisher: name: Università degli Studi di Napoli Federico II
Year: 2006

description: Il lavoro di tesi è stato sviluppato nell’ambito del progetto, finanziato dal M.U.R.S.T. su delibere CIPE, dal titolo “Potenziamento della rete di ricerca in acquacoltura per lo sviluppo del settore in Campania”.
Guardando all’introduzione di nuove specie quale valida strategia di sviluppo per l’acquacoltura, scopo della ricerca è stato quello di valutare l’adattamento di Psetta maxima all’ambiente mediterraneo in risposta all’adozione di particolari soluzioni impiantistiche.
Infatti, tale specie, largamente allevata sulle coste atlantiche di Francia e Spagna, sfruttando le acque fredde superficiali, necessita di cardinali termici alquanto bassi e non riscontrabili, almeno in superficie, nell’acque dell’area mediterranea.
Tale difficoltà è stata superata con l’utilizzo di  prototipi di gabbia sommergibili che, unitamente al sistema di ancoraggio, sono stati progettati per variare  la quota di localizzazione in profondità. Le difficoltà legate alla somministrazione di alimento anche fino a 40 metri dalla superficie sono state superate con l’utilizzo di particolari distributori automatici in grado di trasportare l’alimento direttamente all’interno della camera di allevamento.
In questo modo sono stati instaurati due cicli di allevamento partendo, per il primo, da avannotti inviati con metodo a secco dalla Francia, in pezzature da 5 e 30 g e, per l’altro, da giovanili di circa 10 g trasportati dalla Galizia con metodo tradizionale.
In entrambi i casi, la risposta da parte dei soggetti allevati è da ritenersi positiva. Per quanto riguarda i dati di accrescimento,  sebbene condizionati dalle difficoltà di una sperimentazione condotta in ambiente marino, per altro in profondità, si sono stimati valori in linea con quelli ottenuti con prove di allevamento in gabbie galleggianti in Spagna.
I risultati sin qui ottenuti, soprattutto per quanto riguarda l’adattamento della specie considerata, confermano che in ambienti mediterranei lo spostamento in profondità rappresenta una  soluzione concreta per l’allevamento di Psetta maxima.

La ricerca analizza i fattori che influenzano le iniziative di commercializzazione e promozione della carne bovina per il mantenimento dell’allevamento e lo sviluppo del territorio nel contesto della regione Auvergne (Francia). Nello specifico, ci domandiamo quali siano le condizioni a livello territoriale che favoriscano l’emergenza e lo sviluppo di un progetto collettivo di valorizzazione della carne bovina. A tal scopo, proponiamo un’analisi del sistema territorio in tre diverse dimensioni: quella materiale, quella ideale e quella organizzativa. Il caso di studio a cui abbiamo applicato l’analisi è quello del progetto “Fin Gras du Mézenc” che ha ottenuto nel 2013 l’Indicazione Geografica Protetta (IGP). I risultati ottenuti evidenziano il ruolo di alcune caratteristiche del territorio e le interazioni delle.

We derive global bounds for the gradients for minimal graphic functions of linear growth only on one side. Then we can obtain a Liouville type theorem with such growth via splitting for tangent cones of $\Si$ at infinity. When, in contrast, we do not impose any growth restrictions for minimal graphic functions, we also obtain a Liouville type theorem under a certain non-radial Ricci curvature decay condition on $\Si$. In particular, the borderline for the Ricci curvature decay is sharp by our example in the last section.

description: Un percorso per lo sviluppo locale. I cluster di industrie creative nelle piccole città e nelle zone rurali della Spagna
Molte zone rurali europee sono ancora alle prese con notevoli problematiche di sviluppo. L’Unione Europea, per il periodo 2014-2020, propone la rilevazione delle attività locali prendendo in considerazione “valori non di mercato” ed esternalità positive. Le industrie creative sono interessanti attività da considerare, perché aggiungono valore all’identità e al patrimonio culturale locale, dando alle aree rurali dei vantaggi competitivi. Questi problemi sono discussi in questo articolo, focalizzato
sulle industrie creative che operano nelle piccole città e nelle zone rurali spagnole, sottolineandone luci ed ombre. In particolare, il contributo propone un quadro teorico e metodologico per l’analisi delle industrie creative nelle aree rurali, sulla base del concetto di cluster; quindi passa ad esaminare i cluster creativi individuati nei territori considerati; infine analizza l’impatto sociale ed economico dei cluster creativi individuati sulla piccola città di Teruel.

Tra le recenti tendenze della ricerca geografica vi è lo studio del ruolo delle
leadership formali o informali nella rigenerazione dei territori marginali o in declino. In questo contributo, presentiamo una ricerca su una regione rurale della Romania (quella della città di Rupea), che è stata fortemente colpita dalla transizione sociale ed economica del Paese avvenuta vent’anni fa, e che è situata in un’area economicamente depressa. L’analisi della situazione attuale dimostra la necessità di continuare le iniziative di leadership in questo territorio. Esse, infatti, svolgono un
ruolo significativo sia nella salvaguardia delle caratteristiche del paesaggio culturale (soprattutto del patrimonio edificato) sia nei processi di rigenerazione economica e sociale, in senso sostenibile, delle comunità locali.

Negli ultimi anni l’importanza del turismo enogastronomico è andata costantemente aumentando e questo sia in termini di domanda sia in termini di offerta. Il successo di un itinerario enogastronomico discende dal suo valore esperienziale, ossia dalla sua capacità di mettere il turista nelle condizioni di fare esperienza. Fondamentale è il coinvolgimento della comunità locale che assume il ruolo di interlocutore privilegiato.
Il progetto, mediante l’indagine diretta ottenuta attraverso interviste rivolte
ai turisti enogastronomici, si pone come obiettivo di analizzare gli itinerari enogastronomici disponibili e di produrre una cartografia sul tema delle strade del vino.

Culture, nourriture et vin comme patrimoine des territoires rurales
Au cours des dernières années, l’importance du tourisme du vin n’a pas cessé
d’augmenter, et ce tant en termes de demande, tant en termes d’approvisionnement.
Le succès d’une route du vin dépend de sa capacité à offrir des expériences, c’est à dire, de sa capacité à permettre aux touristes d’entrer en contact avec la communauté locale et la production d’un territoire. La question clé est la participation de la communauté locale qui assume le rôle d’interlocuteur clé. Le projet, grâce à l’enquête directe obtenue au moyen des entretiens avec les touristes, vise à analyser les visites disponibles et la construction d’une cartographie sur le thème des routes des vins.

description: Innovazione organizzativa in agricoltura: nuovi strumenti per una pianificazione territoriale integrata
Lo sviluppo dell’agricoltura dipende, sempre più, dalla capacità dei soggetti
decisionali di adottare forme di progettazione integrata che mirino alla creazione di network verticali e orizzontali capaci di promuovere lo sviluppo rurale. La traduzione in pratica di tale approccio integrato ha comportato la creazione di specifici strumenti network-based tesi a promuovere uno sviluppo rurale basato sulla trasversalità degli attori e dei settori. Partendo da tale premessa, nel presente contributo sono stati analizzati due particolari strumenti di programmazione integrata attuati in Italia: i contratti di filiera e i distretti rurali. Obiettivo è stato quello di esaminare non solo il reale stato di attuazione di tali strumenti, ma anche la loro efficacia, verificando se l’insieme degli strumenti operativi di filiera siano diventati dei reali strumenti operativi piuttosto che semplici enunciati teorici.

L’innovation organisationnelle dans l’agriculture: de nouveaux outils pour une planification territoriale intégrée
Le développement de l’agriculture dépend de plus en plus de la capacité des
décideurs à adopter des formes de planification intégrée qui visent à créer un réseau vertical et horizontal capable de promouvoir le développement rural. La mise en oeuvre de cette approche intégrée a conduit à la création d’outils network-based qui visent à promouvoir un développement rural basé sur la transversalité des acteurs et des secteurs. À partir de là, dans cet article les auteurs ont analysé deux outils de programmation intégrée mis en oeuvre en Italie: les contrats de filière et les districts ruraux. L’objectif de cet article est celui d’examiner non seulement l’état actuel de la mise en oeuvre de ces instruments, mais aussi leur efficacité, c’est-à-dire de vérifier si l’ensemble des outils de soutien aux filières et aux districts ruraux sont devenus des véritables outils opérationnels plutôt que de simples énoncés théoriques.

Bed load proppant transport during slickwater hydraulic fracturing: insights from comparisons between published laboratory data and correlations for sediment and pipeline slurry transport

description: Bed load transport is the movement of particles along the top of a bed through rolling, saltation, and suspension created by turbulent lift above the bed surface. In recent years, there has been a resurgence of interest in the idea that bed load transport is significant for proppant transport during hydraulic fracturing. However, scaling arguments suggest that bed load transport is only dominant in the laboratory and is negligible at the field scale. I review laboratory experiments that have been used to develop concepts of bed load transport in hydraulic fracturing. I also review the scaling arguments and laboratory results that have been used to argue that viscous drag, not bed load transport, is dominant at the field scale. I compare literature correlations for fluvial sediment transport and for pipeline slurry transport with published laboratory data on proppant transport in slot flow. The comparisons indicate that fluvial transport correlations are suitable for predicting the rate of sediment erosion due to flow of proppant-free fluid over a bed. The pipeline slurry correlations are suitable for predicting the ability of proppant that is already in suspension to flow in bed transport without settling, but only if the aspect ratio of the flowing region in the slot is close to unity. This can occur at the laboratory scale, but not in the field. The comparison indicates that at low rates of proppant flow, the equilibrium bed height in a laboratory proppant transport experiment can be predicted from pipeline slurry correlations. However, as the volumetric flow rate and the aspect ratio of the flowing region in the slot increase, the applicability of the pipeline slurry correlations breaks down. Laboratory experiments using higher volumetric flow rate indicate that bed load transport rates are too low to be significant at the field scale, even if the flow velocity is very high.

description: We study the Dirichlet problem for minimal surface systems in arbitrary dimension and codimension via mean curvature flow, and obtain the existence of minimal graphs over arbitrary mean convex bounded $C^2$ domains for a large class of prescribed boundary data. This result can be seen as a natural generalization of the classical sharp criterion for solvability of the minimal surface equation by Jenkins-Serrin. In contrast, we also construct a class of prescribed boundary data on just mean convex domains for which the Dirichlet problem in codimension 2 is not solvable. Moreover, we study existence and the uniqueness of minimal graphs by perturbation.

Culture della migrazione e costruzione degli immaginari

description: Cultures of Migration and Imaginative Construction of Mobility
As complex socio-spatial phenomenon, migration has always and everywhere been present in human history, constituting a crucial factor in the circulation of culture, wealth and power. Numerous theoretical approaches have been followed in attempts to account for it, and the forms, rhythms, and typologies of migration have been described in studies which often do not hesitate to put forward explanations on a continental scale and even cross-continental comparisons. This essay offers innovative readings which focus on the cultural and imaginary dimension of migration. In adopting a communicative perspective, it tries to go beyond “etiological” approaches to migration, such as those based on “push-pull” models. At the same time, the essay attempts to free our understanding of migration from strait-jacket conceptions of paratactic
series of spaces blindly determined by natural and political borders, restoring to it the liminal geography which generates its own special modes of cultural representation and territoriality.

Cultures de la migration et construction des imaginaires
Phénomène socio-spatial complexe, la migration accompagne l’histoire humaine dans son universalité, en constituant un des facteurs cruciaux de production et de circulation de culture, de richesse, de pouvoir. De nombreuses approches théoriques essayent d’en donner des explications plus ou moins exhaustives. De même, les formes, les rythmes, les typologies de la migration sont décrits dans des nombreuses études, par
des thématisation qui s’articulent à différentes échelles. Cet essai explore la relation entre la culture de la migration et l’imaginaire migratoire. En assumant une perspective communicationnelle, il cherche à dépasser les approches “étiologiques” à la migration, tels les modèles push-pull. En même temps, cet article propose de soustraire le fait migratoire à la logique parataxique, dominée par le pouvoir aveugle des espaces et des confins, en le restituant à la territorialité liminaire qui génère les cadres géographiques de sa représentation appropriée.
