Une palette intentionnelle et significative : le symbolisme des couleurs dans quelques romans zoliens

2018

In naturalist novels, aiming to depict the reality as faithfully as possible, colours are particularly important, and need to be carefully selected. An attentive reader of Zola’s Rougon-Macquart series might notice a very special use of colours that are often charged with an important symbolic value: being not only an ornament or a detail, they frequently influence and/or express the characters’ features. The proposed classification shows some most relevant examples of Zola’s conception of colours in selected parts of the series.

Qualitative characteristics of four Sicilian monofloral honeys from Apis mellifera ssp. sicula

2023

Four monofloral honeys, obtained from the Sicilian black bee by foraging on thistle, sulla, chestnut and eucalyptus, were studied. Results showed that the phenolic composition of chestnut honey was the highest (316 mg gallic acid equivalent GAE/kg), while that of sulla honey was the lowest (122 mg GAE/kg). Data confirmed a correlation between the total phenol content and colour intensity in chestnut honey, which was the darkest of the four samples. Sulla honey showed the highest antioxidant activity, while eucalyptus honey had the highest mineral content (K, Ca, Mg, and Na). Thistle honey showed the most intense floral and fruity aromas, as well as an intense -yellow colour. Principal compo…

Hunting for new physics signals in the LHC era

2021

Actualment, el ME de física de partícules és capaç d’explicar satisfactòriament tres de les quatre interaccions fonamentals de la matèria: fortes, febles i electromagnètiques. Tot i això, hi han molts aspectes que aquesta fantàstica teoria no és capaç d’explicar i, sens dubte, ha d’haver alguna cosa més enllà d’aquesta teoria. En aquesta tesi es pretén descobrir si hi ha algun indici a les dades actuals dels acceleradors que suggerisca l’existència de nova física (NF). Pretenem, per tant, determinar fins a quin punt alguns dels models de NF que han sigut proposats a la literatura poden ser plausibles tenint en compte les dades actuals. D’aquesta forma, serem capaços de trobar restriccions s…

Effectiveness of Preservative Treatments on Coloured Ruditic Building Stones

2009

:  The dark grey Breccia di Billiemi and the Ammonitico Rosso of Piana degli Albanesi, two coloured stones widely used in monuments both outdoor and indoor in Sicily, undergo significant decay as effect of weathering: colour change and development of surface microcracks which affect not only the chromatic aspect but also the state of aggregation. In a previous study (Fracture and Failure of Natural Building Stones, 2006, Springer, Dordrecht, The Netherlands: 329), such effects were successfully reproduced on laboratory samples by means of artificial accelerated weathering and the different response of veins and grains to the ageing agents was related to the microstructure of stones. In this…

Differences in Chromatic Sensitivity Estimated Using Static and Dynamic Colour Stimuli

2017

Abstract The current study reports on a novel computerised colour vision test employing static and dynamic stimuli. The aim of the study was to assess if static and dynamic stimuli result in comparable chromatic discrimination thresholds when participant’s age is taken into account. Participants (n = 20) were 21 to 77 years old, had normal colour vision and no history of any eye disease. They all participated in two sessions estimating chromatic sensitivity with static and dynamic stimuli, respectively, with six directions in colour space varying either along the red-green (RG) or yellow- blue (YB) directions. We found no significant differences in chromatic thresholds along a tritan axis o…

Colour Terms in Five Linguistic Images of the World: The Semantic Perspective

2022

Social and cultural factors shape the linguistic perception of colour. At the same time, colour terms co-create the linguistic image of the world, which allows us to interpret reality and profile our statements and beliefs. This paper presents six basic colour terms: white, black, red, green, yellow, and blue (both as adjectives and as nouns) in the five different linguistic images of the world of the following languages: English, French, Italian, Polish, and Japanese. The methodological framework is based on cultural linguistics theory and the basis of semantics. The study explores denotative and connotative meanings of colour terms with their collocations. The data gathered from monolingu…

Juguetes trágicos para adultos: sexualidad y perversiones del cuerpo en las bañistas de Picasso (Dinard, verano de 1928)

2023

El presente artículo busca ofrecer un análisis en torno a un conjunto de pinturas de pequeño formato que Pablo Picasso realizó durante sus vacaciones en Dinard el mes de agosto de 1928. Estas supusieron una transformación pictórica radical, además de una breve etapa fascinante que afianzaron decisivamente las perversiones monstruosas del cuerpo y su sexualidad en la obra del pintor malagueño. Para ello, será necesario hacer un breve repaso sobre los años anteriores a 1928 para comprender el origen de esta fractura pictórica, además de destacar su huella en algunos cambios significativos que Picasso adoptará en su pintura posterior a esta misma fecha. 

Novel functional chitosan and pectin bio-based packaging films with encapsulated Opuntia-ficus indica waste

2021

Abstract The aim of this work was to study the effect of adding red prickly pear, as wasted source of antioxidants on various characteristics of novel functional (antioxidant) chitosan and pectin film formulations. Four types of prickly pear material were used: fruit pulp or peel, as powdered extracts and as aqueous extracts. Prickly pear peel extract was shown to possess higher antioxidant properties than fruit pulp. The antioxidant power of extracts was pretty high, around 1000 mgAAE∙100 g−1 for extract and that of all films around 100 mgAAE∙100 g−1 for films. Even though some changes in thickness, moisture content, water solubility, oxygen permeability and water vapor permeability of fil…
