Questioning the effect of the real exchange rate on growth: New evidence from Mexico
No full textThis study provides new evidence showing that the real exchange rate (RER) does not play an important role in the growth of Mexican GDP. Economic growth is not an automatically predetermined result of relative price correction, and it is important to consider distinctive aspects of national institutional arrangements (fiscal and monetary, for example) for understanding theoretical causality of demand. The empirical results show public expenditure is an overlooked variable in regressions where the exchange rate affects product growth. After incorporating public expenditure, the RER impact on growth becomes insignificant. For its part, public expenditure has a positive and significant effect on GDP in the long term. The RER does not lead to greater GDP since exports are not stimulated through price.Fil: Medici, Florencia. Universidad Nacional de Moreno; Argentina.

«A Dachau c'é posto per tutti». Dal Terrore alla normalità: il campo di concentramento nella stampa tedesca, in Studi Storici, LXV, 2024, n. 3
No full textThis article provides an overview of the forms of communication used by the German press after the Nazi seizure of power to describe the newly introduced concentration camps. It analyses a varied sample of «independent» German newspapers which were not part of the National Socialist press, highlighting the linguistic and narrative patterns used in different types of publications at different key moments in 1933. The author, differing from the traditional view on Gleichschaltung, argues that the extensively developed web of newspapers in the Weimar Republic helped the National Socialists adapt their messages to various social groups, making it possible to use the camps as a threat for the working class and, simultaneously, as a tool to achieve consensus among the middle class

Maestros espirituales del papa Francisco: Hugo Rahner, Miguel A. Fiorito, Gaston Fessard
No full textArtículos en revistasEl actual Papa se ha formado en la escuela de los Ejercicios espirituales de S. Ignacio de Loyola. Este trabajo examina las raíces de este aprendizaje espiritual y el influjo de los principales maestros (Hugo Rahner, Migel A. Fiorito, Gaston Fessard) en su interpretación dl carisma de la Compañía de Jesús: el magis, el discernimiento, la charitas discreta, la dialéctica inscrita en el adagio "Non coerceri maximo, contineri tamen a minimo divinum est. Para ello el autor analiza el texto de los Ejercicios espirituales que Jorge M. Bergoglio impartió a los obispos españoles (2006). De esta forma, el artículo muestra que la espiritualidad ignaciana es una seña de identidad de su pontificado.Pope Francis was trained in the school of Saint Ignatius' Spiritual Exercises. This article develops the roots of this spiritual learning and the influence of leading teachers (such as Hugo Rahner, Miguel A. Fiorito, Gaston Fessard) in the interpretation of the charism of the Society of Jesus: magis, discernment, charitas discreta, dialectic inscribed in te adage "Non coerceri maximo, contineri tamen a minimo divinum est". The author examines the text of the Spirituals Exercises that Jorge M. Bergoglio offered the Spanish Bishops (2006). In this way, this study shows that Ignatian Spirituality is a hallmark of Francis' pontificate.info:eu-repo/semantics/publishedVersio

Large-Eddy Simulation of a Tunnel Ventilation Fan
No full textIn this paper we discuss a computational method focused on the prediction of unsteady aerodynamics, adequate for industrial turbomachinery. Here we focus on a single rotor device selected from a new family of large tunnel ventilation axial flow fans. The flow field in the fan was simulated using the open source code OPENFOAM, with a large-eddy simulation (LES) approach. The sub-grid scale (SGS) closure relied on a one-equation model, that requires us to solve a differential transport equation for the modeled SGS turbulent kinetic energy. The use of such closure was here considered as a remedial strategy in LES of high-Reynolds industrial flows, being able to tackle the otherwise insufficient resolution of turbulence spectrum. The results show that LES of the fan allows to predict the pressure rise capability of the fan and to reproduce the most relevant flow features, such as three-dimensional separation and secondary flows
Valorisation of the industrial hemp residue from essential oil production by recovery of cannabidiol and chemo-enzymatic conversion to cannabielsoin
No full textThe production of essential oils by steam distillation is invariably associated with large amounts of organic waste which is normally disposed of or returned to the fields, although it may still contain some valuable components. In particular, Cannabis sativa essential oil produced by steam distillation of the apical part of industrial hemp plants yields a soaked biomass residue that may contain high-value cannabinoids. From the perspective of sustainable exploitation of agricultural resources, a method to extract cannabidiol (CBD) from such waste was demonstrated and scaled-up, using bioethanol as a renewable bio-based solvent and without requiring chromatographic separation, with an overall yield of 10.1 mg CBD per g waste. The work paves the way to an integrated complete utilisation of industrial hemp byproducts. Furthermore, two alternative lipase-mediated chemo-enzymatic derivatisations have been designed and optimised for the conversion of the recovered CBD into cannabielsoin (CBE), an underexploited cannabinoid with attractive bioactivity. The processes are practical and efficient, with 31-47% isolated yields and green metrics comparing well with the established chemical alternatives
Mapping the Integration of Urban Air Mobility into the Built Environment: A Bibliometric Analysis and a Scoping Review
No full textUrban Air Mobility (UAM) has the potential to revolutionize urban transportation, largely with the deployment of Unmanned Aerial Vehicles (UAVs), commonly known as drones. After an initial stage focused on technology requirements, research is now shifting toward investigating operational requirements, which are unavoidably affected by urban characteristics. This study aims to explore the implementation of UAM services within urban environments by mapping the current scientific landscape from a city-focused perspective. Following a systematic search procedure, a bibliometric analysis was conducted on studies published between 2010 and 2024, examining over 350 articles that address UAM and urban-related topics. Trends in publication volume and scientific impact were analysed, along with influential manuscripts, collaborations, and leading countries in the field. Through a keyword co-occurrence analysis, five main research themes were identified: air traffic management, risk assessment, environmental factors (wind and noise), and vertiport location. These themes were further explored through a scoping review to assess current research and emerging directions. The findings highlight that urban characteristics are not just operational constraints but also fundamental elements that shape UAM strategies, influencing UAV path planning, safety, environmental constraints, and infrastructure design. Future research directions include the development of urban digital twins, comprehensive urban spatial databases, and multi-objective optimization frameworks to support the effective implementation of UAM into cities
Advancing the building materials reclamation: An evaluation method for the disassembly potential of glass facade systems
No full textThe construction sector is responsible for producing and landfilling high volumes of construction and demolition waste. Design for disassembly (DfD) is deemed a promising strategy to establish a circular building process, enabling the easy separation of material and components at the end of life. Despite efforts to promote DfD, only a few applications of this strategy currently exists, and most buildings are not designed to be disassembled at the end of life. These non-DfD compliant building systems represent a possible source of materials and components, according to the concept of building as a materials bank. The ease of deconstruction of these systems should be evaluated to understand their harvesting capacity and circular potentiality. The purpose of this research is to evaluate the DfD level of the widely distributed facade systems in the high-rise building. Specifically, the unitized curtain wall, the stick facades, and the structural glass facades. In this research, a method to evaluate the DfD level of these facade systems has been developed, including various parameters grouped in three sets, such as the technological, economic and environmental ones. The application and validation of this method allowed to identify, among those investigated, the facade technology that is easier to disassemble. Further improvements to the evaluation method would involve fine-tuning the identified parameters to enhance accuracy
Noninvasive positive pressure ventilation in the assessment of extrinsic tracheal stenosis
No full textAirway stenting is a palliative measure to assure ventilation in inoperable patients with extrinsic tracheal compression caused by a mediastinal mass [1].In patients with extrinsic tracheal stenosis caused by a mediastinal mass, an airway stent is a palliative measure to relieve airway obstruction. However, the self-expanding force of the stent may be insufficient to force a rigid stenosis. Our goal was to report a simple strategy to indirectly estimate the rigidity of the stenosis and predict airway patency after inserting the stent. Before the procedure, the inspiratory and expiratory flows and their ratio were evaluated under spontaneous breathing and after positive pressure ventilation generated by a facial mask. In patients with stenosis successfully treated with a stent (n = 11), we found significant changes in expiratory (2.3 +/- 0.7 vs 2.8 +/- 0.7; p = 0.03) and inspiratory (1.5 +/- 0.6 vs 2.5 +/- 0.9; p = 0.001) flows and a reduction of their ratio (1.4 +/- 0.3 vs 1.1 +/- 0.2; p = 0.01) whereas no significant changes were observed in patients (n = 2) whose stent failed to force the stenosis. In these cases, a tracheostomy was performed to assure ventilation. Our simple strategy may help physicians predict airway patency after stenting or plan alternative treatments in patients with rigid stenosis difficult to force by stenting
