El Two-Color Kodachrome y su inserción en The Llight in the Dark (Clarence Brown, 1922): primera y única exhibición pública del proceso experimental …
2014
El Two-Color Kodachrome fue un proceso experimental de color de la Eastman Kodak Company, inventado por John G. Capstaff (en 1913 para fotografia fija y desde finales de 1914 adaptado al celuloide), y el primer metodo fotoquimico de color sustractivo que se aplico a la cinematografia. Se introdujo en un unico largometraje comercial, que supuso a la vez la primera exhibicion publica del sistema: The Light in the Dark (Clarence Brown, 1922). Pese a las buenas criticas, despues quedo restringido a la experimentacion dentro de la compania y a cortometrajes. Este articulo examina el sistema de color en si mismo, asi como el modo en que se inserto en la pelicula, de la que no han sobrevivido ni s…

Lamentos al son del arpa. La imagen del rey David penitente en la pintura valenciana del Barroco
2015
Este artículo parte de dos lienzos de Pablo Pontons y Vicente Guilló para el estudio de la imagen del rey David, especialmente en su tipo iconográfico de David penitente. Formulado originalmente en las miniaturas medievales que se apoyaban en su papel de salmista y fundador de la música sacra, esta tipología tomó episodios de su vida que se convirtieron en modelos de penitencia. El trabajo estudia la tradición cultural convencionalizada de la gura de David, su patronazgo musical y la continuidad del tipo del rey penitente en el Barroco, tanto en grabados como en programas visuales como los de Pontons y Guilló para Morella y Alcalà de Xivert, respectivamente. Este uso didáctico per…
THE OLIGARCH AND THE PAINTBRUSHES: A BIOGRAPHICAL SKETCH OF ANDREU GARCIA, PRIEST = EL OLIGARCA Y LOS PINCELES: BREVE SEMBLANZA DEL PRESBÍTERO ANDREU…
2014
The documents regarding the Valencian priest Andreu Garcia († November 1452) show a quite interesting character. Garcia’s family belonged to local oligarchy. Moreover, he had a substantial income related with the Cathedral. He had contact, too, with Carthusians, Observant Friars and probably with Beghards (the books of his library suggest this last idea). Garcia took part, as an intermediary or as a sponsor, in many artistic orders that involved the best workers and the best customers of the city. Besides, he had a strong relationship with painters like Simó Llobregat, Jaume Mateu, Gonçal Sarrià and Joan Reixac. The priest could also have practiced painting, judging by the belongings that w…
Pervivencia de motivos islámicos en el Renacimiento: El lema «ʼIzz Li-Mawlānā Al-Sulṭān» en las puertas del retablo mayor de la catedral de Valencia …
2018
El aprecio que se tuvo por los tejidos islámicos desde el Medievo es patente en la pintura religiosa. A través de estas líneas se analiza la pervivencia de motivos ornamentales en el Renacimiento, en concreto, el uso de letras árabes a partir del estudio de tres escenas de las puertas del retablo mayor de la catedral de Valencia pintadas por los Hernandos. En ellas los maestros copiaron un tejido nazarí con una inscripción cuya traducción ha pasado inadvertida hasta este momento y que plantea distintas hipótesis sobre su utilización en la obra.The appreciation of Islamic textiles since the Middle Ages is evident in religious painting. The aim of this paper is to analyze the survival of orna…
"That's Real! That's What You Want!": Producing Fear in George A. Romero's Dawn of the Dead (1978) vs Zack Snyder's remake (2004)
2011
International audience; This article examines traditional oppositions between terror and horror in Dawn of the Dead (1978) and its recent remake (2004), by focusing on one of the major changes made by the producers of the remake: the use of running zombies, which emphasizes the danger the creatures represent to the characters, and enables the film-makers to resort to the kind of cheap startle effects that abound in contemporary slasher and action movies. That the living dead of 1978 were slow-moving allowed for contemplation of their pathetic state and questioned the border between living and dead. The 1978 film underlined how incompatible the living dead were with such techniques that rely…
Sheet Metal Hydroforming Technology - State-of-the-Art
2016
The present paper describes the current status of hydroforming technology in today’s global market that focuses on energy use in respect to increasing requirements especially from the automotive industry with its renaissance after the economic crisis. A vast hydroforming classification and the restrictions and drawbacks for a wider market share are also presented.
A simple experiment to characterize material formability in tube hydroforming
2001
Abstract In tube hydroforming processes an internal fluid pressure is utilized to form the material on a properly shaped die; during the process the material axial movement is favoured by the axial feeding of an active punch. In the paper a simple experiment is presented aimed to investigate the influence of the main process variables on material formability. This equipment has enabled an extensive experimental investigation; furthermore a numerical analysis based on the finite element technique has been performed and a ductile fracture criterion has been implemented to predict the insurgence of bursting defects.
Valorization of alginate for the production of hydrogen via catalytic aqueous phase reforming
2018
Abstract Alginate, a carbohydrate abundant in the outer cell wall of macroalgae, was subjected to catalytic aqueous phase reforming (APR) to produce hydrogen using a 3% Pt/C commercial catalyst. The performance of the process was evaluated according to the conversion of the carbon to gas, the hydrogen yield and the hydrogen selectivity. The catalyst and feed amount, temperature, reaction time, pH and the presence of H2 were modified to understand the dependence of the outcome of the process on these parameters. The presence of the catalyst was fundamental in order to increase the hydrogen yield compared to the uncatalyzed reaction, and it can be reused without activity loss. In addition, it…
Geomorphing effect of sand fences in primary dunes of Gulf of Riga
2022
Finding a the most appropriate solution for the problems caused by coastal eros ion is very important, as erosion prevention and habitat management measures must promote the restoration of the natural balance (order of things before anthropogenic disturbances) and restore the coastal status quo as much as possible [6; 2].Dune fences are a very widespread erosion management tool on developed sandy coastal areas due to ease of installation, inexpensiveness, and generally positive public attitude [1]. Effectiveness and impact of fences have also been studied in many places around the world, however previous studies in Latvia have been very limited and episodic [16].This article shows the obser…
