Radiation-engineered functionalized nanogels as platform for biomedical nanocarriers and bio-hybrid, hierarchically assembled nanostructures

2011

Radiation technologies can be considered as choice methodologies for the creation of new functional materials at the nanoscale, the challenge being now the integration of these and other novel nanomaterials into new materials and products. The possibility of generating nanoscalar PVP-based hydrogels particles, with reactive functional groups for subsequent bioconjugation, using industrial type accelerators has been demonstrated. These functional nanoparticles are under evaluation as nanocarriers for targeted release of drugs, but can also be considered as useful building blocks for the assembly of nanostructured materials with controlled architecture. In particular, molecular recognition st…

Ogni impresa umana di educazione è sempre un tentativo, riuscito o meno, di portare risposta ad un fondamentale bisogno di riconoscimento. Questo è, secondo un primo significato che possiamo chiamare affettivo, bisogno, per essere, di essere riconosciuti nell'essere; mentre, secondo un altro significato che è etico o culturale, bisogno di essere aiutati ad entrare in un universo simbolico, innanzitutto quello cui si è originariamente consegnati. La crescita educativa è un'opera di personalizzazione, in senso storico ed esistenziale, della consegna e dell'appello che essa porta

Study of the Curing Process of DGEBA Epoxy Resin Through Structural Investigation

2015

In this work, a multi-scale approach with different analytical methods is applied to study the curing process and the structural properties of a diglycidyl ether of bisphenol A (DGEBA) epoxy resin. This monomer, thermally cured using 4,4′-diaminodiphenilsulfone (DDS) as hardener, is analyzed after 10, 45, 90, and 120 min of reaction time at 180 °C to obtain information on samples with different cross-linking densities. Samples are also characterized after extraction in acetone in order to obtain structural information on the insoluble parts. For this purpose, differential scanning calorimetry (DSC), dynamic mechanical thermal analysis (DMTA), solid-state nuclear magnetic resonance (ss-NMR),…

Fundamental solutions for general anisotropic multi-field materials based on spherical harmonics expansions

2016

Abstract A unified method to evaluate the fundamental solutions for generally anisotropic multi-field materials is presented. Based on the relation between the Rayleigh expansion and the three-dimensional Fourier representation of a homogenous partial differential operator, the proposed technique allows to obtain the fundamental solutions and their derivatives up to the desired order as convergent series of spherical harmonics. For a given material, the coefficients of the series are computed only once, and the derivatives of the fundamental solutions are obtained without any term-by-term differentiation, making the proposed approach attractive for boundary integral formulations and efficie…

Ode laica per Chibok e Leah

2019

The volume contains two short poems by Nigerian Nobel Laureate Wole Soyinka ("No, He Said!", dedicated to Nelson Mandela, from the Author's 1988 classic collection "Mandela's Earth and Other Poems", and the recent "Mandela Comes to Leah", written purposely for this volume), along with the most recent long poem in five parts "A Humanist Ode to Chibok, Leah", published in English for the first time in 2019. The poem, and indeed the entire volume, denounces all forms of fundamentalism and fanaticism as opposed to secular humanism. Soyinka pays tribute to the girls abducted in Chibok and 15 year-old Leah Sharibu, one of the 108 girls abducted from Dapchi in 2018, comparing her firm refusal to r…

Buon andamento dell’amministrazione e attività di vigilanza

2010

Nel saggio viene esaminata la funzione amministrativa di vigilanza, alla stregua dei principi di legalità e buon andamento dell’amministrazione, mettendone in luce la natura eclettica e complessa, perché costituita, non solo da un potere ausiliario di controllo, che è stato sempre presente in tutte le tappe evolutive dell’istituto, ma, soprattutto, da poteri di amministrazione attiva, di vario tipo ed intensità, in ragione delle diverse formule via via scelte dal legislatore per regolamentare la realtà sociale ed economica. Tra questi poteri di amministrazione attiva, il potere di direzione (o indirizzo) ed il potere di regolazione costituiscono gli elementi caratterizzanti di due specie di…
