Music, Religious Communities, and the Urban Dimension: Sound Experiences in Palermo in the Sixteenth and Seventeenth Centuries
2018
Negli ultimi anni la ricerca musicologica ha rinnovato il proprio interesse nei confronti delle istituzioni musicali palermitane, sottolineando l'importanza della ricerca d'archivio per condurre a una ricostruzione del modo concreto in cui la musica risuonava in un contesto specifico. Questo approccio parte da una visione che considera l'elemento musicale quale componente essenziale dell'esperienza urbana, secondo i modelli della cosiddetta 'Urban Musicology' che riconosce la funzione svolta da tutti i luoghi di un dato spazio, non soltanto dalle grandi chiese con le loro cappelle musicali, ma anche dalle istituzioni meno in vista. In questa prospettiva occorre considerare il concetto di “s…
The Definition of Syllable in Aristotle’s Poetics
2015
This paper deals with the theory of syllable in Aristotl's Poetics. As known, the main difficult of this text are the strange examples of syllables 'syllable is gr without a as well as with a, as in gra'. My proposal is to read this definition in strict connetion with the definition of stoichion in the same text, ad in context of the whole Corpus aristotelicum. In the definiton of stoicheion, wich introduce the faumous classification of linguistic sounds in 'vowels' (phoneenta) 'non-vowels' (aphona) and 'semivowels' (hemiphona) is difficult to understnad what 'hemiphona' are, and why Aristotle call them with this name, if we admit that hemiphona are countinous sounds as 's' or 'r'. that are…
Simulation of laser generated ultrasound with application to defect detection
2008
Laser generated ultrasound holds substantial promise for use as a tool for defect detection in remote inspection thanks to its ability to produce frequencies in the MHz range, enabling fine spatial resolution of defects. Despite the potential impact of laser generated ultrasound in many areas of science and industry, robust tools for studying the phenomenon are lacking and thus limit the design and optimization of non-destructive testing and evaluation techniques. The laser generated ultrasound propagation in complex structures is an intricate phenomenon and is extremely hard to analyze. Only simple geometries can be studied analytically. Numerical techniques found in the literature have pr…
Task-specific ionic liquid for the depolymerisation of starch-based industrial waste into high reducing sugars
2014
Development of a simple route for the catalytic conversion of starch-based industrial waste (potato peels) and potato starch into reducing sugars was investigated in two ionic liquids for comparison – 1-allyl-3-methylimidazolium chloride [AMIM]Cl and 1-(4-sulfobutyl)-3-methylimidazolium chloride [SBMIM]Cl. Over a two hour period, a 20 wt% solution containing up to 43% and 98% of reducing sugars at low temperature in aqueous [SBMIM]Cl was achieved for the starch-based waste and the potato starch, respectively. In addition, the use of microwave and low frequency ultrasound to perform the depolymerisation of the raw starch-based material was explored and compared with conventional heating proc…
Emerging opportunities for the effective valorization of wastes and by-products generated during olive oil production process: Non-conventional metho…
2015
Abstract Background A large amount of wastes and by-products are generated during olive oil production process. Traditionally, these products have been considered as a problem. However, they constitute a great source of high-added value compounds, which have the potential to be used as food additives and/or nutraceuticals. Therefore, valorization of wastes and by-products from food industry kills two birds with one stone and addresses both the use of waste and by-products and societal health, thus greatly contributing for a sustainable food chain from an environmental and economical point of view. Scope and approach In the present review, current and new insights in the recovery of high-add…
TRANS-FUSIMO – A novel system for treatment support for FUS applications in moving abdominal organs
2018
Computer based treatemnt support for FUS therapy of moviving abdominal organs is essential due to great intrinsic challenges: the target moves due to breathing and may be occluded by the rib cage. In the EU project TRANS-FUSIMO we have developed a sophisticated software system that connects to a FUS transducer and an MRI. This enables physicians to conduct safe, effective and efficient ablation of tumors in the moving liver.
ULTRASOUND-ASSISTED AND ENZYME-ASSISTED EXTRACTION OF FRUCTANS AND PHENOLICS FROM PARSNIP (PASTINACA SATIVA L.)
2019
Parsnip (Pastinaca sativa L.) is a vegetable that gained attention due to its significant content of fructans, besides macronutrients and other biologically active compounds. The major compound of fructan class is inulin, an ingredient with prebiotic properties used in pharmaceutical and functional food industries. The main purpose of this study was to evaluate the extraction yield of fructans and phenolics in fresh and dried parsnip root following non-conventional techniques (ultrasound and enzyme -assisted extraction) and to compare it to that of the traditional method. Extraction was performed in water, as eco-friendly solvent. Ultrasound-assisted extraction was optimized for different e…
Electrotechnologies, microwaves, and ultrasounds combined with binary mixtures of ethanol and water to extract steviol glycosides and antioxidant com…
2017
The aim of this work was to investigate the potential use of non-conventional technologies (microwaves, ultrasounds, pulsed electric fields, and high voltage electrical discharges) to enhance the extraction of high-added value compounds (mainly stevioside and rebaudioside A), and antioxidants (total phenolic compounds, flavonoids, chlorophylls, and carotenoids), from Stevia rebaudiana leaves. After treatment at equivalent energy, a supplementary diffusion was performed until 1 h. Results demonstrated that when water (100%) was used as solvent, the maximum recovery of stevioside (50.8 ± 0.1 mg/g) was obtained after ultrasound-assisted extraction, while microwave allowed the highest yields of…
Hätätilanteiden äänihavainnot ja toimintakyky : musiikinpsykologinen tarkastelu äänien merkityksestä osana tilannetietoisuuden ylläpitämistä ja tunte…
2016
Hätätilanteiden äänihavainnot ja toimintakyky on monitieteinen tutkimuskokonaisuus, jolla vastataan kysymyksiin siitä, miten ääni-informaation tilannetietoisuutta ylläpitävää roolia tulkitaan onnettomuustutkintaselostuksissa ja miten äänien synnyttämät kokemukset vaikuttavat toimintakykyyn. Tutkimuksen aineistoa ovat Onnettomuustutkintakeskuksen vesiliikenneonnettomuuksien tutkintaselostukset kymmenen vuoden ajalta, tutkimuskeskus Merikotkan internet-sivujen kautta tehdyn kyselyn vastaukset sekä merenkulun turvallisuuskoulutuskeskus Meriturvassa toteutetut haastattelut. Tutkimuksessa hyödynnettiin laadullista analyysia ja narratiivista tutkimusperinnettä sekä sovellettiin onnistuneesti eri …
Auditory perceptual learning : evidence from electrophysiological recordings in rodents and humans
2018
Yllättävät muutokset äänimaailmassa viestittävät yleensä selviytymisen kannalta tärkeistä vihjeistä, joten niiden nopea ja automaattinen havaitseminen on tärkeää. Tietoinen harjoittelu mahdollistaa havainto-oppimisen ja oppimisen seurauksena hermostoon muodostuu uusia muistijälkiä. Varhaisessa kehityksessä herkkyyskauden aikana muistijälkien muodostuminen, ihmisellä erityisesti puheäänille, on automaattista, eikä siihen vaadita tietoista harjoittelua. Toisaalta perinteisesti on ajateltu, että herkkyyskauden jälkeen vain aktiivinen harjoittelu johtaa uusien muistijälkien muodostumiseen. Muutoksen havaitsemisen hermostollista perustaa voidaan tutkia mittaamalla aivojen sähköisiä jännitevastei…
