Valutazione del profilo di rilascio e dell'attività biologica di sostanze attive veicolate mediante sistemi particellari a matrice lipidica
Il Bambù
2008
Il volume fa parte di una collana dal titolo Tecnologia dei Materiali per un'Architettura Sostenibile, che raccoglie i risultati di ricerche, sperimentazioni ed esperienze didattiche condotte dall'autrice negli ultimi anni, presso l'Università degli Studi di Palermo. Ogni volume della collana è dedicato allo studio di uno specifico materiale da costruzione e dei suoi derivati, delle loro peculiarità e possibili applicazioni nel costruito al fine di offrire agli studenti, ai professionisti e ai tecnici del settore, un quadro generale dello stato dell'arte ed un motivo in più per una scelta consapevole di materiali conformi alle esigenze di sostenibilità ambientale e tecnologica, oggi inderog…
Escultores del sonido: prácticas musicales creativas como elemento de transformación social
2020
El principal objetivo de esta investigación es mostrar de qué manera los usos de la tecnología planteados por músicos sin formación académica (“no músicos”), ofrecen un nuevo marco para la transformación social a través de sus prácticas musicales creativas. Como metodología de trabajo se utilizó la investigación etnográfica y la muestra se conformó a través de trece participantes con perfiles profesionales y trayectorias vitales de gran diversidad, con un patrón de coincidencia común: no tener formación musical académica (conservatorio). Como instrumentos y técnicas se emplearon las propias de esta metodología: las entrevistas individuales y grupales, el análisis documental de plataformas d…
Signal processing techniques for robust sound event recognition
2019
The computational analysis of acoustic scenes is today a topic of major interest, with a growing community focused on designing machines capable of identifying and understanding the sounds produced in our environment, similar to how humans perform this task. Although these domains have not reached the industrial popularity of other related audio domains, such as speech recognition or music analysis, applications designed to identify the occurrence of sounds in a given scenario are rapidly increasing. These applications are usually limited to a set of sound classes, which must be defined beforehand. In order to train sound classification models, representative sets of sound events are record…
Preliminary Investigation of Biogenic Amines in Type I Sourdoughs Produced at Home and Bakery Level
2022
During a survey for isolating sourdough lactic acid bacteria (LAB), 20 dough samples produced at the bakery level (BL) or home-made (HM) were collected. An enzyme-based colorimetric method revealed a total biogenic amines (BAs) concentration in the range 41.4–251.8 ppm for six (three BL and three HM) sourdoughs characterised by unpleasant odours. Eight BAs generally investigated in foods were identified and quantified from these six samples by ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC–MS/MS). Only one HM sample contained almost all analysed BAs. Tryptamine was exclusively detected in HM sourdoughs (0.71–24.1 ppm). Putrescine, tryptamine, …

A multi-objective Pareto design approach for simultaneous control of thinning and springback in complex stamping operations.
2009
Abstract In sheet metal forming operations design, optimization problems have to be solved in order to reach optimal process conditions. In these problems, there are some crucial issues to be taken into account: - most of the problems are multi objective problems, generally characterized by conflicting objectives: the definition of proper parameters aimed to prevent both springback and fracture is a typical example of an optimization problem in sheet metal forming characterized by conflicting goals; - in an industrial environment a great interest would be focused on the availability of a cluster of possible optimal solutions instead of a single “almost optimal” solution. Taking into account…
