Il Tesoro del Collegio dei Gesuiti di Trapani

2012

Nel saggio vengono per la prima volta censiti, analizzati e contestualizzati nella temperie culturale e cronologica di riferimento diciotto manufatti in argento. Si tratta del corredo di suppellettili liturgiche sopravvissute alla soppressione dell'ordine della Compagnia di Gesù di Trapani. Le inedite opere pubblicate sono state prodotte da maestranze siciliane, trapanesi e palermitane, attive tra la fine del XVI secolo e il 1819.

An evaluation of the microscopical counting methods of the tape in hirst-burkard pollen and spore trap

1981

Abstract Three different sampling units in current use and different sampling strategies were tested. Randomly placed microscope fields are good in estimating the daily mean concentration, but very big sample size is needed. Traverses across the slide in systematic order are best to estimate the shortterm concentrations and diurnal variation. A formula for the estimation of the error in one transverse traverse is given. Twelve transverse traverses in systematic order is also enough to estimate the daily mean concentration. One or two traverses along the length of the slide give often unreliable estimates because of the irregularities in the transverse variation of the particle concentration…

Adenoviral vector-based COVID-19 vaccines-associated cerebral venous sinus thromboses: Are those adverse events related to the formation of neutrophi…

2022

In March and April 2021 several countries temporarily suspended vaccinations with adenoviral vector-based COVID-19 vaccines. Concerns of national regulators particularly regarded very rare cases of cerebral venous sinus thrombosis after immunization with this type of vaccine. Until now, these adverse events were interpreted as standard hypercoagulable events, but their clinical characteristics suggest that they may actually represent unique thrombotic disorders referred to as immunothrombosis. In this paper it is speculated that it is possible that immunothrombosis after this type of vaccine results from formation of neutrophil extracellular traps (NETs) in veins affected by stagnant blood …

Species differences, influence of dose and application on biotransformation of phenol in fish.

1983

1. The metabolism of phenol in goldfish (Carassius auratus), rainbow trout (Salmo gairdneri) and goldenorfe ide (Leuciscus ideus melanotus) was compared. All three species produced phenyl sulphate, quinol sulphate and phenyl glucuronide. 2. The dose dependence of metabolism of phenol in goldfish was investigated. When the concn. of phenol was increased from 0.2 to 2 mg/l medium, that glucuronylated increased from 7 to 16% and that sulphated decreased from 63 to 47%. 3. The influence of mode of exposure on metabolism of phenol in goldfish was examined. Dietary exposure and uptake from medium was compared with i.p. injection. There was less metabolism in the order: dietary exposure greater th…

Ranking world tourist destinations with a composite indicator of competitiveness: To weigh or not to weigh?

2019

Abstract This paper contributes a weighted composite indicator of competitiveness for 136 world tourist destinations. To that end, Data Envelopment Analysis and Multi-Criteria-Decision-Making techniques are used with raw indicators from the 2017 edition of the Travel & Tourism Competitiveness Report of the World Economic Forum (WEF). An outstanding feature of our approach is that weights are endogenously generated. Furthermore, the role played by several variables in tourism competitiveness is assessed using truncated regression and bootstrapping. The ranking of world tourist destinations produced by our weighted composite indicator of competitiveness is, however, fairly similar to that der…

Il turismo a Trapani nel contesto delle destinazioni turistiche siciliane

2006

La provincia di Trapani, nel contesto delle destinazioni turistiche siciliane, rappresenta un punto di riferimento per chi crede che sia possibile sviluppare il turismo puntando sul miglioramento dei servizi di comunicazione e di ricezione offerti al turismo incoming. Il potenziamento dell’aeroporto di Trapani attraverso l’applicazione delle tratte sociali e l’aumento dei collegamenti con gli aeroporti più importanti d’Italia, ha generato un incremento degli arrivi dei passeggeri che ha avuto forti ripercussioni sul movimento turistico verso le destinazioni turistiche della provincia. Notevole è stato, in questi ultimi anni, l’interesse mostrato dagli imprenditori verso la creazione di un p…

Fenología de los bracónidos (hymenoptera, ichneumonoidea, braconidae) del pirineo andorrano

2006

Phenology of the Braconidae (Hymenoptera, Ichneumonoidea) at Andorra has been conducted/studied using a Malaise trap after a one-year cycle during 1993. A total of 1.892 specimens, representing 23 subfamilies and 79 genera were sampled. About 93.7% of the captures were koinobiont braconids, whereas 6.3% belonged to idiobiont braconids. The annual phenology has been characterized through the correlation between the evolution of the collected braconids and the weather (meteorological conditions). The maximum of the populations were registered between the two rain periods. In fact, the family Braconidae shows an abundance peak from middle of May to end of August, due to the xerothermic conditi…
