This essay is a study which is intended to explore how a well-known makeup company, M.A.C., uses semiotics and pragmatics in their advertisements and how the consumer’s reaction corresponds with what is proposed in the theories. Three printed advertisements were analyzed by the author and six qualitative interviews were conducted with Swedish women of different ages. The analysis of the advertisements identified semiotic and pragmatic features including linguistic and non-linguistic signs, cultural myths, metaphors, similes, pronouns, deixis, visual parallelism as well as the use of Relevance Theory such as enrichment. The results revealed that M.A.C. Cosmetics marketing strategies correlate to, or can be explained by, key theories within pragmatics and semiotics. The results of the interviews show that the majority of the interviewees react correspondingly with what is proposed in the Theoretical Background chapter and the research has validated the theories and confirmed them as useful and effective analytical tools for examining advertising texts. It was also established that the ​advertiser appears to be aware, consciously or not, of​ the cognitive processes involved​ ​in the interpretation of advertisements which Relevance Theory explains, such as enrichment.

Ce travail de thèse est centré sur la compréhension des mécanismes mis en jeu lors de l’impression d’encres à base de nanoparticules d’argent en jet d’encre dans le but d’optimiser la production de fines (<100 µm) pistes conductrices performantes et homogènes. L’impression jet d’encre se décompose en plusieurs étapes : l’éjection de gouttelettes picovolumétriques, l’impact sur le support, l’étalement et le séchage. La phase de séchage est une phase complexe sujette aux phénomènes de transfert de matière comme l’effet coffee ring. Cet effet, dû au flux capillaire qui induit un mouvement du centre vers les bords de la goutte, conduit la majorité des particules en suspension sur les bords du motif imprimé. L’objectif de ce travail est de décrire et de comprendre précisément les mécanismes qui opèrent et qui conduisent à ces effets de transfert de matière pour les limiter, voire les annuler et ainsi garantir la production de pistes conductrices fines et homogènes aux performances élevées. Pour atteindre cet objectif, trois axes de travail ont été développés: (i) Une première étude s’est concentrée sur l’analyse des différentes phases régissant la vie d’une goutte éjectée en jet d’encre. L’identification et l’optimisation des paramètres clés influençant la morphologie des gouttes jet d’encre après séchage ont été réalisées avec un focus particulier sur l’influence de la température du support. Quatre indices géométriques sont proposés pour caractériser quantitativement l’homogénéité du profil des gouttes produites. (ii) Une seconde partie du travail s’est spécifiquement concentrée sur la phase de séchage des gouttes picovolumétriques pour comprendre les phénomènes engagés. Une modélisation du séchage des gouttes est notamment proposée pour permettre une meilleure compréhension des phénomènes de transfert de matière observés. (iii) Enfin, une dernière partie s’intéresse à la production par jet d’encre de fines lignes conductrices (cas de gouttelettes juxtaposées). Des corrélations entre la morphologie des lignes, celle des gouttes individuelles et les performances électriques seront établies afin de produire des systèmes optimisés. / This thesis focuses on the understanding of the mechanisms involved in the inkjet printing of silver nanoparticles-based inks in order to optimize the manufacturing of thin (width <100 µm) conductive tracks with high and homogeneous performances. Inkjet printing can be divided into several phases: the ejection of picovolumetric droplets, the impact on the substrate, the spreading and the drying. The drying phase is a complex phase prone to particle migration phenomena such as coffee ring effect. This phenomenon, due to the capillary flow which implies a movement from the center to the edges of the drop, drives most of the suspended particles towards the edges of the printed patterns. The aim of this work is to describe precisely and understand the mechanisms which operate and lead to the transfer effects in order to limit or even eliminate them and guarantee the production of performing and homogenous fine conductive lines. To achieve this objective, three paths of investigation were developed: (i) a first axis deals with the study of the different phases of the droplet generation process. Parameters impacting the dried droplet morphology are identified and optimized with a focus on substrate temperature. Four geometrical indexes are designed to characterize quantitatively the dried droplet profile homogeneity. (ii) A second axis specifically studies the drying phase of picovolumetric droplet in order to understand the phenomena occurring during this phase. A modelling of droplet drying is set up in order to understand the forces influencing the matter transport. (iii) Finally, a last axis studies the print of thin conductive lines composed of several printed droplets partially superimposed. Correlations between line morphology, droplet morphology and electrical conductivity are established in order to produce optimized systems.

Este artículo explora las conexiones entre el trabajo profesional como historiador de Alberto Flores Galindo, su papel como intelectual público y la cultura política de izquierda en la que él se formó como miembro de la llamada generación del 68. El artículo muestra que, como partícipe de una forma de hacer política en la cual la palabra impresa desempeñó un papel crucial, Flores Galindo desarrolló una creativa y obsesiva relación con el libro y la cultura impresa,cuya reconstrucción nos ayuda a entender los mecanismos de formación de un intelectual público.---This article explores the connections between the work of Alberto Flores Galindo as a professional historian, his role as a public intellectual, and the leftist political culture in which he was formed as a member of the so-called 1968 generation.The article shows that, as a participant in a style of doing politics in which the printed word played a crucial role, Flores Galindo developed a creative and obsessive relationship with the book and the printed culture, the reconstruction of which helps us to understand the mechanisms which go into the formation of a public intellectual.

The goal was to build a machine that could rapidly prototype PCBs using a moving light source and photoresist. The project failed, as the UV light did not make it through the lenses used to concentrate it. Better lenses and a laser would allow it to function better.
