The Artistic Commitment of Kenyon Cox: An American Neoclassical Artist

2016

At the end of the nineteenth century, the United States had undergone deep transformations. The second Industrial Revolution had created huge amounts of new wealth and power. This led to an alteration of the urban social fabric and to a repositioning of the country on the international scene.Since the 1870s, the American Renaissance had been a vehicle for the diffusion of new values and new concepts. As a broad neoclassical movement in the arts, it was committed to a rewriting of the country’s national past.At the time, Kenyon Cox (1856-1919) distinguished himself as one of the major artists of the movement, but also as one of its most influential critics and theorists. Cox developed theori…

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…

Microhardness of demineralized enamel following home bleaching and laser-assisted in office bleaching

2015

Background There is little data regarding the effect of tooth whitening on microhardness of white spot lesions. This study was conducted to investigate the effect of home-bleaching and laser-assisted in-office bleaching on microhardness of demineralized enamel. Material and Methods Forty bovine incisors were selected and immersed in a demineralizing solution for 12 weeks to induce white spot lesions. Enamel blocks were prepared and randomly assigned to two groups of 20 each. The first group underwent home bleaching with 15% carbamide peroxide which was applied for 8 hours a day over a period of 15 days. In the second group, in-office bleaching was performed by 40% hydrogen peroxide and powe…

Archaeometric evidence attesting production of indigenous archaic pottery at Monte Polizzo (Western Sicily)

2012

Excavations at the proto-urban indigenous settlement of Monte Polizzo (western Sicily) have not yielded so far any evidence of in-situ ceramic production (i.e. kiln structures). However several archaeological concerns put forward to consider it as a likely production centre of pottery during the Archaic age. In this paper a first attempt to check the compositional correspondence between ceramic fabrics and local clay sources has been made. A comprehensive archaeometric investigation of native pottery, mainly composed of matte-painted table ware dated from the 7th to the 4th century BC, recovered from the Acropolis of Monte Polizzo has allowed the identification of five distinct ‘Paste Compo…

Microradiography and confocal laser scanning microscopy applied to enamel lesions formed in vivo with and without fluoride varnish treatment

1996

The aim of the present investigation was to combine 2 techniques suitable for lesion characterization: quantitative microradiography (TMR) and confocal laser scanning microscopy (CLSM) on in vivo induced lesions with and without a fluoride varnish (Duraphat(R)) treatment. Orthodontic bands were attached to premolars to be extracted for orthodontic reasons to induce enamel caries on the buccal surfaces. In the caries development part of the study, 1 tooth of each pair received at the start 1 topical application with the fluoride varnish Duraphat(R), the contralateral tooth serving as untreated control. All teeth were extracted after 4 weeks. In the caries progression part, the premolars were…

Tra mito e rito: aspetti della cultura figurativa imerese nel tardo V secolo a.C.

2015

This study revisiting finds with figural decoration from early excavations of the residential area of the town of Himera has sparked a new approach to reconstructing the figural repertoire, mythographic heritage and spectrum of ritual and sacred practices wihch must have characterised this colonial city before its destruction at the end of the 5th century B.C. The author has studied, in particular, various clay arulae and the figural decoration on vases painted by the Himera Painter, which were used in the ritual life of the domestic quarters of the town and whose subject matter appears to be derived exclusively from the sagas of Thessaly and Boeotia. The main theme of the illustrated myths…

Using ultrasound transmission velocity to analyse the mechanical properties of teeth after in vitro, in situ, and in vivo irradiation.

2000

Ultrasound transmission velocity (UTV) in isotropic material as a measure for the modulus of elasticity was correlated to mechanical properties. Changes in micromechanical properties of radiated teeth and influence of the oral cavity were to be evaluated nondestructively. UTV was measured in extracted teeth after 36 Gy and 62 Gy of in situ (enorally, with no contact to the oral cavity) and in vitro irradiation. Relative to controls, teeth subjected to 62 Gy in vivo showed higher UTV values for dentine and enamel. Sound teeth irradiated with 60 Gy in situ also showed higher UTV values for enamel, whereas dentine values were not significantly different from those of control. The mechanical pr…

Fourier transform infrared spectroscopy and the analytical study of sculptures and wall decoration

1997

Abstract An analytical examination of sculpture and wall painting, including several wooden polychromed carvings from Valencian churches (15th–17th centuries) using FT-IR spectroscopy is described. The organic and inorganic compounds used in the works of art and the different artistic techniques used in each historical intervention carried out in the sculptures are identified. The analytical information obtained with this technique on organic and inorganic compounds is extremely useful in the preliminary studies necessary for diagnosis and to decide on the conservation process.

Pilot study on the combination of an organophosphate-based insecticide paint and pyrethroid-treated long lasting nets against pyrethroid resistant ma…

2015

International audience; A pilot study to test the efficacy of combining an organophosphate-based insecticide paint and pyrethroid-treated Long Lasting Insecticide Treated Nets (LLINs) against pyrethroid-resistant malaria vector mosquitoes was performed in a real village setting in Burkina Faso. Paint Inesfly 5A IGR™, comprised of two organophosphates (OPs) and an Insect Growth Regulator (IGR), was tested in combination with pyrethroid-treated LLINs. Efficacy was assessed in terms of mortality for 12 months using Early Morning Collections of malaria vectors and 30-minute WHO bioassays. Resistance to pyrethroids and OPs was assessed by detecting the frequency of L1014F and L1014S kdr mutation…
