Ma‘dûle Önermelerde Varlıksal İçerik Sorunu: Fahreddin er-Râzî-Kutbüddin et-Tahtânî Tartışması
2019
This paper addresses discussions in post-Avicennan Arabic logic on the definition of metathetic propositions and their status in relation to existential import requirements, focusing on the arguments made by Fakhr al-Dīn al-Rāzī (d. 606/1210) and the counter-arguments by Quṭb al-Dīn al-Rāzī al-Taḥtānī (d. 766/1365), who both establish their positions in the framework drawn by the most prominent figure in the tradition of classical Arabic logic, Avicenna (Ibn Sīnā, d. 428/1037). In the latter’s works, the problem of the existential import requirement in metathetic propositions (ma‘dūla) are thoroughly discussed and Avicenna seems to have presumed the existential import as a truth-condition f…
Architettura e città per una nuova identità borghese: 1860-1915
2015
Il contributo focalizza l'attenzione sugli sviluppi architettonici e urbanistici delle città del cuore della Sicilia in un arco cronologico compreso tra 1860 e 1915. Abbozzare un quadro delle opere d’architettura e degli interventi sulla città attuati nella Sicilia centro-meridionale tra l’Unità d’Italia e la prima Guerra Mondiale, significa in buona parte concentrare l’indagine su Caltanissetta, per la quantità numerica e la qualità architettonica delle iniziative intraprese. Enna, invece, sarà elevata nel 1927 a capoluogo di Provincia, dimezzando così il territorio provinciale di Caltanissetta. Caltanissetta e la nascita della sua provincia, la parabola dello zolfo; i traguardi istituzion…

Między Rzymem a Bizancjum – wątki marynistyczne związane z historią Numenoru i jego państw sukcesyjnych w twórczości Tolkiena
2022
J.R.R. Tolkien był jednym z najsłynniejszych autorów klasyki gatunku fantasy, a także bardzo utalentowanym badaczem języków europejskich. Tolkien znał doskonale historię naszego kontynentu od czasów starożytnych i średniowiecznych, dzięki czemu w jego Śródziemiu istnieje niezwykle duża liczba odniesień do rzeczywistych wydarzeń i faktów. Jest to najbardziej widoczne w bitwie na polach Pelennoru, lecz nie jest to jedyne takie świadectwo. Ów autor doskonale posługiwał się historią Cesarstwa Rzymskiego, jak i jego spadkobiercy Cesarstwa Bizantyńskiego, dlatego to właśnie na nich oparł swoją wizję Numenoru oraz jego państw sukcesyjnych, Arnoru i Gondoru. Wraz z nimi pojawiają się w jego pracach…
Modeling the insect mushroom bodies: application to a delayed match-to-sample task.
2013
Despite their small brains, insects show advanced capabilities in learning and task solving. Flies, honeybees and ants are becoming a reference point in neuroscience and a main source of inspiration for autonomous robot design issues and control algorithms. In particular, honeybees demonstrate to be able to autonomously abstract complex associations and apply them in tasks involving different sensory modalities within the insect brain. Mushroom Bodies (MBs) are worthy of primary attention for understanding memory and learning functions in insects. In fact, even if their main role regards olfactory conditioning, they are involved in many behavioral achievements and learning capabilities, as …
The role of contact chemoreception in the host location process of an egg parasitoid
2016
Taste allows insects to detect palatable or toxic foods, identify a mate, and select appropriate oviposition sites. The gustatory system strongly contributes to the survival and reproductive success of many species, yet it is rarely studied in insect parasitoids. In order to locate and assess a host in which they will lay their eggs, female wasps actively search for chemical cues using their sensory organs present mainly on the antennae. In this paper, we studied the role of antennal taste sensilla chaetica in the perception of contact semiochemicals in Trissolcus brochymenae (Hymenoptera: Platygastridae), an egg parasitoid of the brassicaceae pest Murgantia histrionica (Heteroptera: Pentat…
Electrophysiological and Behavioral Responses of Oriental Fruit Moth to the Monoterpenoid Citral Alone and in Combination With Sex Pheromone
2013
The monoterpenoid citral synergized the electroantennogram (EAG) response of male Grapholita molesta (Busck) antennae to its main pheromone compound Z8-12:OAc. The response to a 10-μg pheromone stimulus increased by 32, 45, 54, 71 and 94% with the addition of 0.1, 1, 10, 100 and 1,000 μg of citral, respectively. There was no detectable response to 0.1, 1, or 10 μg of citral; the response to 100 and 1,000 μg of citral was 31 and 79% of the response to 10 μg of Z8-12:OAc. In a flight tunnel, citral affected the mate-seeking behavior of males. There was a 66% reduction in the number of males orientating by flight to a virgin calling female when citral was emitted at 1,000 ng/min ≍1 cm downwind…
New Contributions toPseudonapomyza(Diptera: Agromyzidae) from Spain: Addition of Three New Species
2010
The genus Pseudonapomyza (Diptera: Agromyzidae) includes the main leafminer pests for monocots. Three new species are described that were captured using Malaise traps in "Tinença de Benifassà", "Font Roja" and "Lagunas de La Mata-Torrevieja" (Spain) Natural Parks: Pseudonapomyza curvata n. sp., P. longitata n. sp., and P. sicicornis n. sp. Systematics. Ecological data are discussed.
Enhancer trap infidelity in Drosophila optomotor-blind
2013
Reporter gene activity in enhancer trap lines is often implicitly assumed to mirror quite faithfully the endogenous expression of the "trapped" gene, even though there are numerous examples of enhancer trap infidelity. optomotor-blind (omb) is a 160 kb gene in which 16 independent P-element enhancer trap insertions of three different types have been mapped in a range of more than 60 kb. We have determined the expression pattern of these elements in wing, eye-antennal and leg imaginal discs as well as in the pupal tergites. We noted that one pGawB insertion (omb (P4) ) selectively failed to report parts of the omb pattern even though the missing pattern elements were apparent in all other 15…
Floral volatiles in a sapromyiophilous plant and their importance in attracting house fly pollinators
2015
Floral scent in sapromyiophilous plants often consists of complex blends with not only fetid (e.g., sulfides) but also sweet (e.g., terpenoids) volatile organic compounds and a recent study suggests that both groups of compounds are involved in pollinator attraction. However, little is known about the number and identity of compounds involved in pollinator attraction in these deceptive plants that mimic breeding sites of fly pollinators. In the present paper, we studied flower volatiles of sapromyiophilous Periploca laevigata and their capability to elicit biological responses in one of the pollinator species, Musca domestica. Floral volatiles were collected by dynamic headspace and analyse…
