Baucina-Monte Falcone 2014, indagini nella necropoli.
2016
The aim of this report is to present the results of archaeological samples, executed in order to contrast illegal researches on a necropolis at Baucina, in the northwestern part of Sicily, where Punic, Greek and indigenous traditions coexisted, in a relationship which is the focus of our ongoing investigation. We collected an archeological dataset, whose interpretation is detecting an articulated situation where the interaction between three different ethnic groups gave as result the variety of rituals. The future excavations of the site could increase the perception of this interaction, for a period in which Greeks and Punics designed their spheres of influence of the territories within th…
Attraction of kestrels to vole scent marks visible in ultraviolet light
1995
IN northern Europe, broad four-year oscillations in small rodent and raptor populations are synchronous over hundreds of square kilometers1–6. Crashes in vole populations can induce wide emigration (> 1,000 km) of their predators7 –9, but almost nothing is known about how predators rapidly detect areas of vole abundance. Here we report on laboratory and field experiments on voles (Microtus agrestis) and kestrels (Falco tinnunculus). Voles mark their runaways with urine and faeces, which are visible in ultraviolet light. Wild kestrels brought into captivity were able to detect vole scent marks in ultraviolet light but not in visible light. In the field, kestrels hunted preferentially near ex…
Under my wing: lesser kestrels and jackdaws derive reciprocal benefits in mixed-species colonies
2011
In mixed-species assemblages, antipredator benefits for a timid species nesting close to a more pugnacious one are often reported. Advantages for the protected species are usually manifested in terms of higher reproductive success than conspecifics nesting remote to the protector species. Whether the protector species also accrues any benefit remains untested, and the species-specific behavioral traits underlying enhanced reproductive output in mixed-species associations remain poorly documented. We studied associations between lesser kestrels (Falco naumanni) and jackdaws (Corvus monedula) nesting in rural buildings in the Gela Plain (Italy). We tested for interspecific interactions of jac…

L’immagine dei Normanni di Sicilia nella letteratura latina del XII secolo
2016
La dominazione normanna della Sicilia e dell'Italia meridionale, fra XI e XII secolo, è stata letta e interpretata in vario modo dagli scrittori contemporanei, sia quelli di parte bizantina, sia quelli occidentali. In questo saggio, dopo una breve premessa concernente i principali fatti storici e le relative fonti bizantine, ci si concentra sulla disamina di alcuni fra i principali scrittori e poeti che, tra la fine dell'XI e tutto il XII secolo, si sono occupati della dominazione normanna di Sicilia, cercando di individuare e di illustrare, caso per caso, la visione che essi ebbero dei Normanni conquistatori. Si discorre qui, nell'ordine, di Amato da Montecassino, Goffredo Malaterra, Gugli…
“Com fa faena de fusta”. El retablo renacentista del gremio de carpinteros de Valencia
2021
El gremio de carpinteros de Valencia costeó un nuevo retablo a partir de 1542, que fue realizado por el escultor Damià Gonçalbes. Sus pinturas fueron contratadas con Onofre Falcó, y los temas representados constituyen un discurso autorreferencial que justifica visualmente el viraje en el patronazgo corporativo y dignifica el oficio al vincularlo a san José y otros santos.

Phytochemical investigations of ethanol root bark and stem bark extracts of Cleistochlamys kirkii (Benth.) Oliv. (Annonaceae) yielded a new benzopyranyl cadinane-type sesquiterpene (cleistonol, 1) alongside 12 known compounds (2–13). The structures of the isolated compounds were established from NMR spectroscopic and mass spectrometric analyses. Structures of compounds 5 and 10 were further confirmed by single crystal X-ray crystallographic analyses, which also established their absolute stereochemical configuration. The ethanolic crude extract of C. kirkii root bark gave 72% inhibition against the chloroquine-sensitive 3D7-strain malaria parasite Plasmodium falciparum at 0.01 μg/mL. The is…
Discovery of new antimalarial compounds by use of molecular connectivity techniques.
1999
Abstract Molecular connectivity has been applied to the search for new compounds with antimalarial activity. Linear discriminant analysis and connectivity functions were used to select several potentially suitable drugs which were tested for antimalarial properties by use of an in-vitro micro test which estimates parasite growth by measurement of incorporation of [3H]hypoxanthine. Hexetidine stands out among the compounds selected. Activity assays were performed with Plasmodium falciparum passou and 3CD7 strains, for which the IC50 values (doses resulting in 50% inhibition) were 320 and 400 ng mL−1 respectively. These results are comparable with those obtained for quinine chlorhydrate (IC50…
Dioncophyllines C2, D2, and F and related naphthylisoquinoline alkaloids from the Congolese liana Ancistrocladus ileboensis with potent activities ag…
2017
Dioncophylline F (1), the first 5,8'-coupled dioncophyllaceous alkaloid (i.e., lacking an oxygen function at C-6 and possessing an R-configuration at C-3), was isolated from the recently described Congolese liana Ancistrocladus ileboensis. Two further, likewise Dioncophyllaceae-type, alkaloids, the dioncophyllines C2 (2) and D2 (3), were identified, along with the Ancistrocladaceae-type compound ancistrocladisine B (4), which is oxygenated at C-6 and S-configured at C-3. The structures of the new compounds were determined by spectroscopic, chemical, and chiroptical methods. The stereostructure of 1 was further confirmed by total synthesis. As a consequence of the lack of a methyl group orth…
