Introduzione. Il suono delle cose
2018
This paper introduces the book of the theoretical texts by the composer Federico Incardona (Palermo, 1958-2006), collected and put in order by his students, now stored in the musicological library of Palermo University; it draws a concept map to guide the reader into Incardona’s labyrinthine path. The fundamental concepts, highlighted and analyzed, are: the “inaudito” (what you never heard) as the result of a research in which the composer is involved even physically; the “sign”, as a tool to objectify the unheard; the “tone row” as the order of notes obtained by their bonds with the sensations and experiences: the epiphany of the sound of things: the “tradition” as “permanent revolution”, …
CUZZOLIN P., Napoli M. (a c.di),Ancora su musica e fonetica nella Grecia antica
2006
L'articolo mostra come nella cultura greca antica sia dato di ritrovare, ancor prima di quanto abitualmente si creda, chiare tracce di una conoscenza non banale dei processi fonatori. L'idea che viene esplicitata è che all'interno della scuola pitagorica antica si reperivano nel canale orale umano, equiparato a un tubo sonoro simile a quello degli auli, tre punti che ne frazionavano la lunghezza secondo precisi rapporti in analogia al modo in cui si operava in quegli strumenti musicali, mediante l'apertura e chiusura dei fori praticati nei loro corpi sonori, per ottenere il frazionamento della lunghezza della colonna d'aria.
Multiphoton Absorption of Myoglobin Nitric-Oxide complex: Relaxation by D-NEMD of a Stationary State
2012
ABSTRACT: The photodissociation and geminate recombination of nitric oxide in myoglobin, under continuous illumination, is modeled computationally. The relaxation of the photon energy into the protein matrix is also considered in a single simulation scheme that mimics a complete experimental setup. The dynamic approach to non-equilibrium molecular dynamics is used, starting from a steady state, to compute its relaxation to equilibrium. Simulations are conducted for the native form of sperm whale myoglobin and for two other mutants, V68W and L29F, illustrating a fair diversity of spatial and temporal geminate recombination processes. Energy flow to the heme and immediate protein environment …

Ferritin-Coated SPIONs as New Cancer Cell Targeted Magnetic Nanocarrier
2023
Superparamagnetic iron oxide nanoparticles (SPIONs) may act as an excellent theragnostic tool if properly coated and stabilized in a biological environment, even more, if they have targeting properties towards a specific cellular target. Humanized Archaeoglobus fulgidus Ferritin (HumAfFt) is an engineered ferritin characterized by the peculiar salt-triggered assembly-disassembly of the hyperthermophile Archaeoglobus fulgidus ferritin and is successfully endowed with the human H homopolymer recognition sequence by the transferrin receptor (TfR1 or CD71), overexpressed in many cancer cells in response to the increased demand of iron. For this reason, HumAfFt was successfully used in this stud…
Bright Visible Luminescence in Silica Nanoparticles
2011
International audience; We demonstrate that a porous film of silica nanoparticles emits a bright visible luminescence associated with defects stabilized by oxygen chemisorption at oxygen deficient center sites. Time-resolved spectra excited by a tunable laser allow us to distinguish the luminescence at 1.99 eV, characteristic of the nonbridging oxygen hole center (NBOHC) (Si-O)3 Si-O*, and a fast and a slow emission: the first (lifetime τ ≈ 25 ns) is peaked at 2.27 eV with an excitation spectrum centered at 5.5 eV; the second (τ ≈ 7.5 μs) is peaked at 2.41 eV and is excited around 3.2 and 5.2 eV. Reaction in an air atmosphere leads to the disappearance of the NBOHC luminescence and of the …

Premessa al Volume "Natura della tecnica e tecnica della natura"
2015
L'autrice presenta il tema del volume e cioè l'interrogazione sul rapporto fra natura e tecnica e sul limite che le unisce e le separa.
Natura della tecnica e tecnica della natura
2015
Attraverso i 10 contributi che raccoglie, il volume tenta un'articolazione del rapporto fra natura e tecnica che è anche un attraversamento di alcuni passaggi cruciali della filosofia occidentale e che funge da ricostruzione del loro rapporto.
