Comparison of activity in the 2-propanol dehydration of supported heteropolyacid (photo)catalysts at the gas-solid interface
2015
Catalytic and photocatalytic tests for 2-propanol dehydration to propene were successfully carried out by using binary materials obtained by supporting a Keggin heteropolyacid H3PW12O40 (PW12) via impregnation method and/or solvothermal treatment. The supports used were commercial SiO2 (Mallinckrodt), TiO2 (Evonik P25) and multiwall carbon nanotubes (Sunnano) or home solvothermically prepared SiO2 and TiO2. (Photo)catalytic 2-propanol dehydration was studied in gas-solid regime by using a continuous (photo)reactor working at atmospheric pressure and 80 °C. the reaction was also studied by performing FTIR spectra of the gas-phase over the HPA-support composites, where the 2-propanol had been…
Children Witnessing Domestic and Family Violence: A Widespread Occurrence during the Coronavirus Disease 2019 (COVID-19) Pandemic
2021
Across the world, children and adolescents are exposed daily to toxic levels of violent behaviors, including domestic and family violence. Violence increasingly has permeated and profoundly affected the lives of children, who are the most vulnerable members of society.1 Pediatric societies in Europe and North America have raised great concern over the effect that abusive experiences will have on present and future generations.1, 2, 3, 4 The global spread of coronavirus disease 2019 (COVID-19) during the past year has dramatically worsened the situation, contributing to a further increase in violence and aggression within households. Reports of domestic abuse and family violence have increas…
Timoteo Calvo Ibarra (1799-1879). Un arquitecto valenciano durante el reinado de Isabel II.
2015
In the complex scene of valencian architecture of 19th century, Timoteo Calvo Ibarra should be considered as one of the most representative authors. In his designs and interventions, such as the Literary University, the construction of new Cathedral’s Altarpiece, they are apparent the peculiarities of the first Historicism, coincident with Isabelline period. In this first stage of historicism, the homogeneity and guarantee of good taste that classicism provided was no longer valid as unique option and it will be simultaneous with romantic architecture represented by the first historicist experiences, which will conclude with the burst onto the scene of the eclecticism in the restoration of …
Perspectives for the Treatment of Brucellosis in the 21st Century: The Ioannina Recommendations
2007
Policy Forum. Competing interests: ER has received research grants from Daiichi, Bayer, and Theravance and has served as a consultant to Pfizer, Theravance, Bayer, Wyeth, Rosetta, and BiondVax. Summary Points Brucellosis remains the commonest anthropozoonosis worldwide, and its treatment remains complex, requiring protracted administration of more than one antibiotic. In November 2006, a consensus meeting aimed at reaching a common specialist statement on the treatment of brucellosis was held in Ioannina, Greece under the auspices of the International Society of Chemotherapy and the Institute of Continuing Medical Education of Ioannina. The author panel suggests that the optimal treatment o…

L’abside in facciata: soluzioni “antisismiche” del XVIII secolo in Sicilia
2015
Nel corso del Settecento vennero progettate e costruite in Sicilia facciate chiesastiche caratterizzate da conformazioni curvilinee. Forme convesse e concave, posizionate in corrispondenza del partito centrale della facciata rendono queste strutture assimilabili alle absidi. Scelte di natura estetica hanno inizialmente innescato fenomeni emulativi sulla base della ricezione dei modelli diffusi dalla seconda metà del Seicento in Sicilia dalle incisioni riproducenti le facciate inflesse prodotte dai maestri del Barocco romano. Finora l'interesse verso questi modelli è apparso lo schema interpretativo più pertinente per spiegare gli indirizzi progettuali dei maggiori artefici operanti nel Sett…
Absorption kinetics and swelling stresses in hydrothermally aged epoxies investigated by photoelastic image analysis
2015
Abstract The present work proposes an experimental optical methodology able to measure the transient swelling stresses induced by the water uptake ageing of polymers. In particular, the work describes the implementation of a Photoelastic technique to quantify internal stresses arising during the hydrothermal ageing of cast epoxy samples. The material investigated is a model DGEBA/DDS epoxy system. Curing and post-curing cycles have been optimised in order to obtain a fully cured, high T g , and completely stress free initial condition. Rectangular beam samples were then left in a hydrothermal bath at 90 °C, and regularly monitored by gravimetric and photoelastic analyses. The quantitative e…
La herencia clásica palladiana en dos proyectos catedralicios valencianos: la renovación de la Puerta de los Apóstoles
2005
El presente artículo pretende analizar los proyectos de renovación de la Puerta de los Apóstoles, en la catedral de Valencia. Estos proyectos son los de Vicente Marzo y José García, realizados ambos en el año 1796. A partir de ellos se buscarán sus influencias que remiten, especialmente, a I Quattro Libri dell'Architettura de Palladio. (A)
