Pensare apocalitticamente. La lotta messianica di Sergio Quinzio

Psicologia dell'intelligenza
2011
Quando si parla di intelligenza molti pensano al QI, a quel quoziente di intelligenza misurabile attraverso semplici test psicoattitudinali. Ma in realtà cos'è, come si sviluppa, che cosa è capace di fare l'intelligenza? Per le autrici è quella facoltà umana che ha a che fare con l'ambiente, il DNA, la creatività e diversi altri fattori non tutti definibili mediante questionari.

Gas-Phase Hydrogenation of Propionitrile Catalyzed by LnCu2 (Ln = La, Ce, Pr, Nd)
2007
The hydrogenation of propionitrile over binary copper−lanthanide intermetallic compounds (LnCu2, Ln = La, Ce, Pr, Nd) was studied in the gas phase. The results show that the reaction main product is the primary amine, the n-propylamine. To our knowledge, it is the first time that such behavior is reported for copper catalysts.
Self-assembly mechanism based on charge density topological interaction energies
2017
The packing interactions have been evaluated in the context of the self-assembly mechanism of crystal growth and also for its impacts on the aromaticity of the trimesate anion. The structure of ethylammonium trimesate hydrate (1) measured at 100 K and a charge density model, derived in part from theoretical structures, is reported. Theoretical structure factors were obtained from the geometry-optimized periodic wave function. The trimesic acid portion of 1 is fully deprotonated and participates in a variety hydrogen bonding motifs. Topological analysis of the charge density model reveals the most significant packing interactions and is then compared to a complementary analysis performed by …
Spaghetti Enriched with Inulin: Effect of Polymerization Degree on Quality Traits and α-Amylase Inhibition.
2022
Inulin is considered a dietary fiber and represents a noteworthy ingredient for food biofortification due to its health effects and its neutral taste. The aim of the work was the evaluation of the quality of pasta produced using whole-meal flours of two ancient Sicilian landraces (Senatore Cappelli-CAP and Timilia—TIM) fortified with two types of inulin (long-chain topinambur inulin IT and low-chain chicory inulin IC), at two different levels of substitution (2 and 4%) to evaluate its possible effect on α-amylase inhibition. The color indices L* and a* were mainly influenced by cultivars, while IT improved the sensory attributes, mainly the elasticity sensation, and influenced l…
Preparation of Polymeric Nanoparticles by Photo-Crosslinking of an Acryloylated Polyaspartamide in w/o Microemulsion
2004
Biodegradable polymeric nanoparticles have been prepared by UV irradiation of an acryloylated water soluble polymer by an inverse microemulsion. The starting polymer was a α,β‐poly(N‐2‐hydroxyethyl)‐D,L‐aspartamide (PHEA) partially functionalized with glycidyl methacrylate (GMA) in order to introduce reactive vinyl groups in the side chain. The PHEA‐GMA copolymer obtained (PHG) was crosslinked by UV irradiation of the inverse microemulsion prepared by mixing an aqueous solution of PHG with propylene carbonate (PC)/ethyl acetate (EtOAc) in the presence of sorbitan trioleate (SPAN 85) as surfactant. Nanoparticles obtained were characterized by FTIR spectrophotometry, transmission electron mic…
Involucri Traslucidi in Vetromattone: nuove tecniche di assemblaggio a secco ed incremento prestazionale del prodotto per la riduzione del valore di …
2010
Nel corso del Novecento l’impiego dei diffusori di vetro per la realizzazione di elementi tecnici traslucidi in grado di captare la luce naturale ha subito alterne vicende. Dopo un periodo di intenso utilizzo a cavallo del XIX e XX secolo e dopo la realizzazione, in Europa, negli anni a cavallo tra le due guerre, di alcuni edifici divenuti emblematici del Movimento Moderno, l’impiego di questo prodotto “innovativo” per l’epoca, venne progressivamente “relegato” alle parti più nascoste degli edifici per la “pragmatica” risoluzione di problematiche legate, ad es., alla presenza di particolari vincoli urbanistici senza che, quindi, ne venissero ulteriormente indagate le potenzialità espressive…
MIGLIORAMENTO TECNOLOGICO-PRESTAZIONALE DI UN COMPONENTE INNOVATIVO PER L’INVOLUCRO EDILIZIO - PERFOMANCE IMPROVEMENT OF AN INNOVATIVE BUILDING COMPO…
2016
L’articolo illustra l’attività di ricerca che gli autori, cofounder della SBskin. Smart Building Skin s.r.l., start up innovativa e spin off accademico dell’Università degli Studi di Palermo, stanno conducendo al fine di ottimizzare le performance energetiche di un componente innovativo per facciate e coperture di edifici (dagli stessi brevettato) in grado di ridurre i consumi energetici e di produrre energia pulita dal sole. L’attività che qui si illustra è stata finalizzata all’ottimizzazione del design dei sub-componenti che contribuiscono alla realizzazione dei pannelli traslucidi multifunzionali (realizzati con vetromattoni innovativi, preassemblati a secco e precompressi) ed alla scel…
Pressure-Induced Deformation of Pillar-Type Profiled Membranes and Its Effects on Flow and Mass Transfer
2019
In electro-membrane processes, a pressure difference may arise between solutions flowing in alternate channels. This transmembrane pressure (TMP) causes a deformation of the membranes and of the fluid compartments. This, in turn, affects pressure losses and mass transfer rates with respect to undeformed conditions and may result in uneven flow rate and mass flux distributions. These phenomena were analyzed here for round pillar-type profiled membranes by integrated mechanical and fluid dynamics simulations. The analysis involved three steps: (1) A conservatively large value of TMP was imposed, and mechanical simulations were performed to identify the geometry with the minimum pillar density…
