Paleogenetic and morphometric analysis of a Mesolithic individual from Grotta d'Oriente: An oldest genetic legacy for the first modern humans in Sici…
2020
Abstract Grotta d’Oriente, a coastal cave located on the island of Favignana (Sicily, Italy) is a key site for the study of the early human colonization of Sicily. Inside the cave, during different field excavations, three burials attributable to the Late Upper Palaeolithic and Mesolithic were found. The Mesolithic Oriente B individual, directly dated at 9,377 ± 25 uncal BP, was previously assigned to HV1 haplogroup using a traditional approach. However, it is well known that PCR based methods are prone to erroneous haplotype or haplogroup determination. In order to redefine the mitochondrial lineage of this Mesolithic hunter-gatherer and explore its phylogenetic position, we target-enriche…
Selective recovery of phosphorus as AlPO4 from silicon-free CFB-derived fly ash leachate
2018
The prospect of phosphorus (P) recovery from siliceous fly ash was investigated. The phosphorus content in the pristine fly ash was 1.21%. Obtaining pure phosphorus products from fly ash is very challenging because of high concentration of other elements, silicon (Si) at 17.3% being the major contaminant. The fly ash was fractionated with sieve size of 125 μm to concentrate the phosphorus in the small-size fraction, which also facilitated the removal of 78% of silica (Si) in the solid phase. The fractionated fly ash was treated with 8 M HCl in order to remove 98% of Si by aging (5 h) of leachate until precipitation of Si-gel, and a phosphorus-rich solution is obtained. Iron (Fe) is also con…
IL SITO PREISTORICO DELLO ZUBBIO DI COZZO SAN PIETRO S.I.C. RUPI DI CATALFANO E CAPO ZAFFERANO
2014
All’interno del S.I.C, “Rupi di Catalfano e Capo Zafferano”, alcune delle grotte presenti sono state frequentate dall’uomo fin dalla preistoria. Mettendo a confronto la genesi delle cavità e la loro ubicazione topografica, è evidente che la scelta dei siti consoni a essere usati dall’uomo è marcatamente strategica e ponderata. L’indagine è stata condotta dapprima individuando e raggiungendo i siti noti in bibliografia, dai quali si è cercato di elaborare un modello per individuare nuovi siti che potessero presentare evidenze di frequentazione umana risalenti alla preistoria, soprattutto recente. All’interno di una grotta, Zubbio di Cozzo San Pietro, ubicata ad una quota di 300 m s.l.m sul v…
La flora vascolare e lichenica della Riserva Naturale Grotta Conza (Sicilia nord-occidentale). – Naturalista sicil., s. 4, 33 (1-2): 3-68.
2009
Vascular and lichenic flora of Grotta Conza Nature Reserve (NW Sicily). Based on field investigation, bibliographic and herbarium researches we present a vascular and lichen flora of Grotta Conza Nature Reserve, a protected area of speleological and antropological interest located along the northern slopes of Pizzo Manolfo, very close the city of Palermo. The main outcrops of the area are represented by limestones of mesozoic and tertiary origin, while, bioclimate can be referred to thermomediterranean thermotype with subhumid ombrotype. Landscape, strongly influenced by the past prolonged historical utilization of the territory, shows total absence of primary woodlands, whose place is now …
Combining conjunctive rule extraction with diffusion maps for network intrusion detection
2013
Network security and intrusion detection are important in the modern world where communication happens via information networks. Traditional signature-based intrusion detection methods cannot find previously unknown attacks. On the other hand, algorithms used for anomaly detection often have black box qualities that are difficult to understand for people who are not algorithm experts. Rule extraction methods create interpretable rule sets that act as classifiers. They have mostly been combined with already labeled data sets. This paper aims to combine unsupervised anomaly detection with rule extraction techniques to create an online anomaly detection framework. Unsupervised anomaly detectio…
Visualising political thinking on the screen : a dialogue between von Trotta’s Hannah Arendt and its protagonist
2016
This article analyses Margarethe von Trotta’s film Hannah Arendt: The Woman Who Saw Banality in Evil through its protagonist’s own writings on visual culture, visibility and invisibility in the context of political thinking. We start by clarifying Arendt’s understanding of political theory as an activity aiming to provoke thinking. We then discuss systematically the visual language of the film and offer a typology of its representations of political thinking, subdivided into a part on internalisation and one on externalisation (dialogue). We emphasise von Trotta’s reliance on a negative approach, i.e. the representation of thinking through the absence of any other activity while thinking, c…
La Grotta dei Personaggi di Montevago (AG), una nuova segnalazione di cavità ipogenica in Sicilia
2015
La Grotta dei Personaggi è localizzata in Sicilia occidentale, nei pressi di Monte Magaggiaro, a S del centro abitato di Montevago (AG). Nell’area sono presenti sorgenti termali, caratterizzate da acque cloro-solfate alcalino-terrose con temperatura di circa 40 °C e pH 7. La Grotta dei Personaggi, conosciuta già dai primi anni del 1900 e nota anche per ritrovamenti archeologici, non era mai stata dettagliatamente rilevata e studiata. La cavità si sviluppa prevalentemente in calcari di piattaforma della formazione Inici (Giurassico inf.) e in calcari di scarpata e pelagici della formazione Buccheri (Giurassico inf.-sup.). Si tratta di una cavità sub-orizzontale che presenta uno sviluppo di c…

Memory-Based Mismatch Response to Frequency Changes in Rats
2011
Any occasional changes in the acoustic environment are of potential importance for survival. In humans, the preattentive detection of such changes generates the mismatch negativity (MMN) component of event-related brain potentials. MMN is elicited to rare changes (‘deviants’) in a series of otherwise regularly repeating stimuli (‘standards’). Deviant stimuli are detected on the basis of a neural comparison process between the input from the current stimulus and the sensory memory trace of the standard stimuli. It is, however, unclear to what extent animals show a similar comparison process in response to auditory changes. To resolve this issue, epidural potentials were recorded above the pr…
