Exposure to the agricultural fungicide tebuconazole promotes Aspergillus fumigatus cross-resistance to clinical azoles. [Comini S. is the co-first author; Banche G. is the corresponding author; Cuffini A.M. is the co-corresponding author]
No full textResistance to clinical triazoles in Aspergillus fumigatus is a growing concern for individuals at high risk of Aspergillus infection. Two triazole resistance selection routes are currently being investigated: one occurring in triazole-treated patients in healthcare settings, and the second taking place in the environment due to the widespread use of agricultural triazoles. This study aimed to assess the ability of agricultural azoles to promote cross-resistance to clinical azoles in A. fumigatus. Five A. fumigatus isolates susceptible to clinical azoles were exposed to the triazole 14α-demethylase inhibitor, tebuconazole (TBC), and then antifungal susceptibility tests for voriconazole, itraconazole, posaconazole and isavuconazole were performed. Under TBC selection pressure, all A. fumigatus isolates exhibited resistance to clinical triazoles. However, only two displayed a multiresistant phenotype to clinical azoles. TBC exposure was also associated with delayed conidia formation and progressive absence of conidiation. Noteworthy, no TBC-exposed clones harbored TR34/L98H mutation, as judged by real-time PCR assays. The observation that TBC exposure promotes cross-resistance to clinical triazoles warrants careful and thorough assessment of the human health risk associated with agricultural azoles. The absence of TR34/L98H mutation in cross-resistant A. fumigatus isolates suggests that other cyp51A mutations may be involved in clinical azole cross-resistance

Compositionality properties of SLD-derivations
No full textThe paper introduces a semantics for definite logic programs expressed in terms of SLD-derivations and studies various properties of SLD-derivations by using the above semantics, The semantics of a program is a goal-independent denotation, which can equivalently be specified by a denotational semantics and a transition system. The denotation is proved to be correct, minimal, AND-compositional and OR-compositional. The denotational semantics and the transition system are defined in terms of a set of primitive semantic operators, whose properties are directly related to the properties of the denotation. The SLD-derivations semantics has been designed to act as collecting semantics for a framework of abstract semantics (Comini et al., 1995, 1996). (C) 1999-Elsevier Science B.V. All rights reserved

Written in 2012, Silenzio is a composition for prepared harp inspired by the aesthetics of American composer John Cage and some idiomatic sonorities of the harp. Silenzio was originally commissioned by harpist Giulia Azzurra Rettore, who premiered it during a performance of Musicircus at the English National Opera, London, in 2012. Since then, the piece has received tens of performances internationally, in the UK, Italy, Spain, France, USA, Hong Kong, Chile and Australia.
Silenzio was featured in a dedicated documentary broadcast on Cultural Plaza, Jade Channel TVB, Hong Kong, in 2018, and has been discussed in the dissertation Contemporary Harp Writing: Three Case Studies by Francesca Virgilio.
Silenzio’s preparation features some foil paper wrapped around two strings and three small (possibly Chinese / Oriental) bells hanging from the instrument’s frame, as indicated below. The three small bells, stimulated by some pincé notes, bounce on the strings, while the foil paper creates a deep, drone-like buzzing effect. These objects play on some peculiarities of the instrument, whilst enhancing the musical possibilities of the performer.
Structurally, the composition articulates through varying repetitions and a slowly unfolding harmonic rhythm. Similarly, the piece’s tempo wishes to induce a lack of pulse-perception, evoking an idea of still time: a sort of sonorous silence unable to articulate pulses and heartbeats
SiC Foams Decorated with SnO2 Nanostructures for Room Temperature Gas Sensing
No full textSberveglieri, Giorgio/0000-0003-0080-8117; Ponzoni, Andrea/0000-0001-9955-5118; Comini, Elisabetta/0000-0003-2559-5197; Vakifahmetoglu, Cekdar/0000-0003-1222-4362Cell walls of the commercial silicon carbide (SiC)-based foams were decorated by one-dimensional tin dioxide (SnO2) nanostructures. Thermal evaporation of SnO2 powder with the assistance of a Au catalyst in inert atmosphere caused the formation of SnO2 nanobelts on the pore surfaces. The room temperature (RT) ammonia (NH3) and nitrogen dioxide (NO2) gas sensing behaviors were investigated systematically in both dry and humid air atmosphere with/without UV activation. The results were compared to those for bare SnO2 and SiC. It was shown that SiC/SnO2 composite was efficient to detect low concentration of NH3 (10-50 ppm) and NO2 (1-5 ppm) under humid air and UV activation at RT.TUBITAK (The Scientific and Technological Research Council of Turkey)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [CAYDAG-113Y533]The author wishes to express sincere appreciation to Prof. Gian Domenico Soraru and his team in University of Trento for the N2 adsorption and desorption data.

One-Dimensional Nanostructured Oxide Chemoresistive Sensors
No full textDay by day, the demand for portable, low cost, and efficient chemical/gas-sensing devices is increasing due to worldwide industrial growth for various purposes such as environmental monitoring and health care. To fulfill this demand, nanostructured metal oxides can be used as active materials for chemical/gas sensors due to their high crystallinity, remarkable physical/chemical properties, ease of synthesis, and low cost. In particular, (1D) one-dimensional metal oxides nanostructures, such as nanowires, exhibit a fast response, selectivity, and stability due to their high surface-to-volume ratio, well-defined crystal orientations, controlled unidirectional electrical properties, and self-heating phenomenon. Moreover, with the availability of large-scale production methods for nanowire growth such as thermal oxidation and evaporation-condensation growth, the development of highly efficient, low cost, portable, and stable chemical sensing devices is possible. In the last two decades, tremendous advances have been achieved in 1D nanostructured gas sensors ever since the pioneering work by Comini on the development of a SnO2 nanobelt for gas sensor applications in 2002, which is one such example from which many researchers began to explore the field of 1D-nanostructure-based chemical/gas sensors. The Sensor Laboratory (University of Brescia) has made major contributions to the field of metal oxide nanowire chemical/gas-sensing devices. Over the years, different metal oxides such as SnO2, ZnO, WO3, NiO, CuO, and their heterostructures have been grown for their nanowire morphology and successfully integrated into chemoresistive gas-sensing devices. Hence in this invited feature article, Sensor Laboratory research on the synthesis of metal oxide nanowires and novel heterostructures and their characterization and gas-sensing performance during exposure to different gas analytes has been presented. Moreover, some new strategies such as branched-like nanowire heterostructures and core-shell nanowire structures adopted to enhance the performance of nanowire-based chemical sensor are presented in detail
