Assessment of the insecticidal activity of five essential oils used against the subterranean termite Reticulitermes lucifugus (Rossi) (Blattodea, Rhi…
2023
Among Reticulitermes genus the most abundant species living in Italy is Reticulitermes lucifugus Rossi. This termite is very dangerous to wooden structures of artistic heritage and buildings. The traditional control of R. lucifugus is very difficult resulting in negatively impact on the environment, therefore the use of phytochemical, such as essential oils (EOs), could lead to an alternative to synthetic insecticides, with advantages in reducing environmental risks. In this work we investigated the insecticidal activity of EOs of Citrus bergamia Risso, Syzygium aromaticum L., Foeniculum vulgare Mill., Pelargonium odoratissimum L., and Origanum vulgare L. by inhalation against R. lucifugus …

The cotton aphid, Aphis gossypii Glover (Homoptera: Aphidiidae), is a cosmopolitan and highly polyphagous species causing serious economic damage to numerous plants including Cucurbitaceae. The use of synthetic insecticides represent the main method of control of this aphid, often resulting in resistance to all the major insecticide group. The use of natural products, such as essential oils (EOs), has increased in recent years because they have advantages in reduction of this resistance. Within this research area, we have implement and evaluate the applications of EOs that aim at reinforcing knowledge on the control of this aphid. We investigated the topical application of the EOs of Origan…
ON THE WEIGHT DISPLACEMENT IN CURVE AND THE ROADABILITY OF A 4WS VEHICLE
2013
A simplified theory on the vehicle stability in curve is explained in this paper; it allows the calculation of the force on the wheels during the motion in curve, supposing unchanging the position of the rolling centre; moreover it does not take in account the turn of the wheels and the behaviour of the tires, so that the theory can be applied to 2WS and 4WS vehicles for vertical loads calculation. The virtual simulations of 2WS and 4WS vehicles are executed, extracting all the data interesting the vehicle stability; it needs the distinction between manoeuvrability and handling. The simulations of two different tests are executed: the elk test like manoeuvrability test and a similar one at …

Nel corso del XIX secolo l'idea di popolo e l'idea di nazione hanno prodotto la nascita di nuovi orientamenti nella musica dei paesi slavi della Mitteleuropa. Le fonti cui si sono ispirati i fautori dei movimenti nazionali in Germania, Austria, Polonia, Cekia, Slovenia e Croazia sono state descritte come popolari, ma si tratta in realtà di musiche folkloriche, devozionali, brani d'opera e brani d'autore, che furono usati anche nella musica d'arte (opere e sinfonie), con l'unico scopo di attestare i principi identitari essenziali per la formazione dei futuri stati dopo la caduta dell'impero austro-ungarico. La storia e le tradizioni dei paesi sopra elencati non hanno quasi nulla in comune, s…
Giovanni Marrasio fra Virgilio, Orazio e Properzio
2021
Questo saggio mira a presentare la figura e l’opera poetica di Giovanni Marrasio (Noto, 1400/1404 - Caltanissetta, sett. 1452), umanista siciliano autore dell’«Angelinetum» e dei «Carmina varia», attivo nella prima metà del sec. XV fra la Sicilia e Siena, Firenze e Padova, Ferrara e Napoli, in rapporti con altri umanisti e letterati (Giovanni Aurispa, Antonio Beccadelli, Leonardo Bruni, Enea Silvio Piccolomini, Carlo Marsuppini, Maffeo Vegio, Niccolò Niccoli, Guarino Veronese), potenti uomini di stato (Niccolò III d’Este, Alfonso il Magnanimo) e di chiesa (papa Niccolò V). In particolare, la disamina si concentra sulle suggestioni che Virgilio, Orazio e Properzio hanno esercitato sulla poes…

The essay shows a comparison between Montaigne and Pascal on the theme of life, using the question of movement as a key to reading. From this comparison, Pascal shows a significant closeness to the Greek metaphysical paradigm.
Wavelet Analysis Of Variance Risk Premium Spillovers
2013
In this paper we construct a variance risk premium spillover index among France, Germany, UK, Switzerland and the US. The variance risk premium is measured by the difference between the difference between the (square) of implied volatility and expected realized variance of the stock market for next month. We also construct a spillover index for the constituents of the variance risk premium. The series under investigation exhibit long memory properties. The construction of a total spillover indicator suggested by Diebold-Yilmaz (2009) would then rely on modeling a fractionally integrated Vector Autoregressive Model, which might be subject to errors in specifying the correct lag length and th…
