Terminal tendon cell differentiation requires the glide/gcm complex.
2004
International audience; Locomotion relies on stable attachment of muscle fibres to their target sites, a process that allows for muscle contraction to generate movement. Here, we show that glide/gcm and glide2/gcm2, the fly glial cell determinants, are expressed in a subpopulation of embryonic tendon cells and required for their terminal differentiation. By using loss-of-function approaches, we show that in the absence of both genes, muscle attachment to tendon cells is altered, even though the molecular cascade induced by stripe, the tendon cell determinant, is normal. Moreover, we show that glide/gcm activates a new tendon cell gene independently of stripe. Finally, we show that segment p…
Contamination from polycyclic aromatic hydrocarbons (PAHs) in the soil of a botanic garden localized next to a former manufacturing gas plant in Pale…
2010
The Botanical Garden lies within the city of Palermo, a few meters away from one of the largest unused Manufacturing Gas Plant in Sicily. The total concentrations of PAHs (23 compounds) in the soil of Botanical Garden ranged from 947 to 18,072 microg/kg. The wide range of PAH concentrations (RSD=84%) found in the soil samples indicates heterogeneous levels of contamination in the area and this can be explained by considering the different tree distributions which prevents the homogeneous deposition of pollutants on the soil. Soils collected in the Botanical Garden generally showed the highest PAH concentrations, being almost 2-3 times higher than the concentration samples obtained in the ur…
The Aqua-Planet Experiment (APE): Response to Changed Meridional SST Profile
2013
This paper explores the sensitivity of Atmospheric General Circulation Model (AGCM) simulations to changes in the meridional distribution of sea surface temperature (SST). The simulations are for an aqua-planet, a water covered Earth with no land, orography or sea- ice and with specified zonally symmetric SST. Simulations from 14 AGCMs developed for Numerical Weather Prediction and climate applications are compared. Four experiments are performed to study the sensitivity to the meridional SST profile. These profiles range from one in which the SST gradient continues to the equator to one which is flat approaching the equator, all with the same maximum SST at the equator. The zonal mean circ…

Tra AGCM e ABF il Collegio Coordinamento sceglie il non liquet
2023
L’autore analizza la figura dell’arbitro bancario finanziario, il quale pur non essendo né un giudice né un arbitro, è chiamato in una certa misura a comportarsi “come se fosse tale”, ossia a decidere, secondo diritto, sulla domanda proposta dal cliente. Si sofferma, pertanto, sul principio espresso dal Collegio di Coordinamento dell’ABF con la pronuncia n.2460/2023 in materia di rapporti tra provvedimento sanzionatorio dell’AGCM, in materie diverse dagli illeciti “anti-trust”, disciplinati dal d.lgs. 3/2017. Conclude che, qualora l’accertamento dell’AGCM non sia ancora definitivo, l’arbitro bancario finanziario, come a fortiori il giudice, resta libero di accertare autonomamente la condott…
The Influence of Chemical Composition of Commercial Lemon Essential Oils on the Growth of Candida Strains
2013
Candida yeasts are saprophytes naturally present in the environment and forming colonies on human mucous membranes and skin. They are opportunistic fungi that cause severe and even fatal infections in immunocompromised individuals. Several essential oils, including eucalyptus, pine, cinnamon and lemon, have been shown to be effective against Candida strains. This study addresses the chemical composition of some commercial lemon essential oils and their antifungal potential against selected Candida yeast strains. Antifungal potential and minimum inhibitory concentrations were determined for six commercial lemon essential oils against five Candida yeast strains (Candida albicans 31, Candida t…
Principi di concorrenza e obblighi di motivazione nel procedimento di costituzione di società in house
2019
L’articolo analizza la disciplina degli obblighi di motivazione analitica previsti dalla normativa italiana – ed in particolare dal d.lg. 19 agosto 2016, n. 175 (Testo unico in materia di società a partecipazione pubblica) – per la costituzione o l’acquisto di partecipazioni in “società in house”. L’A. sostiene che, sebbene più rigorosa rispetto alla corrispondente disciplina europea, la normativa italiana sia compatibile con i principi, europei e nazionali, in materia di libera concorrenza e auto-determinazione della p.a. This article analyzes the detailed explanation that the public administration must give in order to create “in-house companies” according to Italian legislation addressed…
Le società in house tra autoproduzione e mercato. Alcune considerazioni sulla costituzione di società in house alla luce del d.lgs. 19 agosto 2016 n.…
2020
L'articolo analizza la disciplina inerente la costituzione delle società in house, così come disciplinata dal recente Testo unico sulle società a partecipazione pubblica (D.lgs. n. 175/2016). Particolare attenzione è dedicata agli obblighi motivazionali di cui all'art. 5 TUSP, interpretati nel quadro europeo dell'in house providing, ed al successivo controllo da parte dell'AGCM.
The Aqua-Planet Experiment (APE): CONTROL SST Simulation
2013
Climate simulations by 16 atmospheric general circulation models (AGCMs) are compared on an aqua-planet, a water-covered Earth with prescribed sea surface temperature varying only in latitude. The idealised configuration is designed to expose differences in the circulation simulated by different models. Basic features of the aqua-planet climate are characterised by comparison with Earth. The models display a wide range of behaviour. The balanced component of the tropospheric mean flow, and mid-latitude eddy covariances subject to budget constraints, vary relatively little among the models. In contrast, differences in damping in the dynamical core strongly influence transient eddy amplitudes…
