Revisiting the Etymology of Greek mégas, megàle, méga
2013
Despite the numerous attempts at clarification that have been made over the past hundred years or so, there are still many doubts surrounding the etymology of Gr. μέγας, μεγάλη, μέγα “big, great, mighty”, especially with regard to the relation between the Greek adjective and forms attested in other Indo-European languages. The paper follows a new track. By having recourse to É. Benveniste’s theory of the structure of the Indo-European root, a stem II *sm-eĝ- is supposed in which *s- could share the characteristics of the so-called ‘mobile s-’. Thanks to this hypothesis most of the pre-existing doubts are dispelled.
Testing explosive bubbles with time-varying volatility: the case of Spanish public debt
2023
In this paper the dynamics of the Spanish public debt-GDP ratio is analysed during the period 1850–2021. We use recent procedures to test for explosive bubbles in the presence under time- varying volatility (Harvey et al., 2016; Harvey et al., 2019, 2020; Kurozumi et al., 2022) in order to test the explosive behavior of Spanish public debt over this long period. We extend previous analysis of Esteve and Prats (2022) where assume constant unconditional volatility in the underlying error process.
Search for photonic signatures of gauge-mediated supersymmetry in 8TeV pp collisions with the ATLAS detector
2015
A search is presented for photonic signatures motivated by generalized models of gauge-mediated supersymmetry breaking. This search makes use of 20.3 fb[superscript −1] of proton-proton collision data at √s = 8 TeV recorded by the ATLAS detector at the LHC, and explores models dominated by both strong and electroweak production of supersymmetric partner states. Four experimental signatures incorporating an isolated photon and significant missing transverse momentum are explored. These signatures include events with an additional photon, lepton, b-quark jet, or jet activity not associated with any specific underlying quark flavor. No significant excess of events is observed above the Stand…
Ulteriori studi sul comportamento agronomico di piante di fragola prodotte in Sicilia
2010
Nowadays, Sicilian growers moved fron traditional summer planting with cold-stored strawberry plants to winter planting using fresh plants. Fresh plants let di anticipate and expand the harvesting period from December to May and produce strawberries with better qualitative parameters. Fresh bare root plants are produced mainly in Spain and Poland but in the last years mountain's nurseries near yhe cultivation fields were set up in Sicily. This work consisted of comparing fresh bare root plants of three cultivars (Camarosa, Candonga, Tudla) coming from three Sicilian and one Poland nurseries. the Sicilian plants were the earliest and gave a yield higher than that of the plants imported from …
Comparing micro-cutting and mini-cutting technique for the clonal propagation of Metrosideros excelsa
2017
public gardens for its foliage and attractive red flowers. M. excelsa plants are commercially propagated by soft and semi-ripe cuttings. Therefore, new and more reliable propagation techniques derived both from conventional and advanced propagation methods should be considered to support Metrosideros nursery development. The mini-cutting and micro-cutting techniques were compared for the clonal propagation of M. excelsa. Ex vitro rooted micro-cuttings resulted superior to mini-cuttings in terms of rooting percentage, root number per cutting and root length by 23.5%, 42.5% and 2.4%, respectively. However, the mini-cutting technique can be considered an alternative reliable propagation method…
