The Human Figure in Drawing and Sculpture

My project as a Senior Scholar has been the study of the human figure through drawing and sculpture. I have worked directly from the model in order to understand the form and structure of the human body. The result of this concentrated study has been a sharpened sense of vision and an increased confidence in the use of materials for both two and three-dimensional representation.

Multidisciplinary approach in the teaching of dental sculpture and anatomy

The purpose of the Dental Sculpture and Anatomy discipline is to introduce undergraduate students to the study of the anatomic and morphological characteristics of permanent and primary human dentition, through classes, books and cognitive and psychomotor activities. This discipline supports the teaching of specific knowledge necessary for a more extensive education, involving interdisciplinarity as a means of knowledge exchange among several areas of dentistry, to achieve comprehensive professional education. Students must recognize the dental morphology from samples of preserved teeth, and reproduce the morphology through three-dimensional models made of stone or wax blocks. In this article, the authors describe the process for producing teeth collars and macro dental models made of stone, their importance and benefits of utilization. The purpose of the study was to encourage the teaching of Dental Sculpture and Anatomy toundergraduate students of the Bauru School of Dentistry, University of Sao Paulo, through activities that would associate theory, practice and the development of manual skills.

Le projet Lbc, une ressource "hybride" au service du traducteur dans le domaine artistique et culturel. Analyse de la terminologie de la sculpture dans les traductions francaises de la Vita di Michelangelo

Il presente lavoro mette in evidenza le principali difficoltà che il traduttore di testi specialistici è chiamato ad affrontare durante la pratica della traduzione. In particolar modo, il nostro studio si concentra sulla figura del traduttore che lavora in ambito artistico : oggigiorno la facilità degli spostamenti e il conseguente aumento del turismo culturale hanno reso la traduzione di dépliant, guide turistiche e cataloghi una pratica necessaria e in continua crescita. L’obiettivo prefissato è quello di verificare l’apporto che le risorse lessicografiche e terminologiche attualmente disponibili danno al traduttore di testi a contenuto artistico. Il nostro lavoro si articola in quattro capitoli. Il primo, di stampo teorico, pone l’accento sulla natura polisemica della parola terminologia (disciplina, metodologia e insieme di termini appartenenti ad un ambito specialistico) e sulla distinzione tra pratica terminologica e traduttiva gettando le basi del secondo capitolo che, partendo dall'esposizione degli ostacoli terminologici incontrati dal traduttore, descrive le lacune dei principali dizionari bilingui italiano-francese e delle basi di dati terminologiche oggi a disposizione. Il terzo capitolo, dedicato alla presentazione del progetto Lessico multilingue dei beni culturali (LBC), ne evidenzia i punti di forza e sottolinea la necessità di creare degli strumenti “ibridi”, concepiti per aiutare il traduttore in ambito artistico. Questa conclusione sarà ulteriormente ribadita nel quarto capitolo, di stampo pratico : l’analisi di una quindicina di termini dell’ambito della scultura (estratti dal corpus de La Vita di Michelangelo, appositamente creato nell'ambito del progetto LBC) mostra l’eccessivo numero di strumenti che il traduttore è costretto a consultare per risolvere adeguatamente le difficoltà incontrate, pratica che non rispecchia più il mestiere della traduzione, all'interno della società dell’informazione, sempre più influenzato dalle scadenze imposte.

MeV ion beam lithography of biocompatible halogenated Parylenes using aperture masks

Parylenes are poly(p-xylylene) polymers that are widely used as moisture barriers and in biomedicine because of their good biocompatibility. We have investigated MeV ion beam lithography using 16O+ ions for writing defined patterns in Parylene-C, which is evaluated as a coating material for the Cochlear Implant (CI) electrode array, a neuroprosthesis to treat some forms of deafness. Parylene-C and -F on silicon and glass substrates as well as 50 μm thick PTFE were irradiated to different fluences (1×1013-1×10161×1013-1×1016 1 MeV 16O+ ions cm−2) through aperture masks under high vacuum and a low pressure (<10−3 mbar) oxygen atmosphere. Biocompatibility of the irradiated and unirradiated surfaces was tested by cell-counting to determine the proliferation of murine spiral ganglion cells. The results reveal that an oxygen ion beam can be used to pattern Parylene-C and -F without using a liquid solvent developer in a similar manner to PTFE but with a ∼25× smaller removal rate. Biocompatibility tests showed no difference in cell adhesion between irradiated and unirradiated areas or ion fluence dependence. Coating the Parylene surface with an adhesion-promoting protein mixture had a much greater effect on cell proliferation.

On the penetration of particles through filters and masks.

El principal objetivo de este trabajo es la evaluación de la eficiencia de filtros y máscaras destinados a la protección de los trabajadores contra partículas sólidas respirables. Se ha diseñado un dispositivo que simula los ciclos respiratorios del ser humano de forma automática. Filtros y máscaras se ensayan en el interior de una cámara, en una atmósfera controlada, y se introducen partículas de polvo en suspensión en su interior. Las partículas de polvo pasan a través de los filtros y se toma una muestra en vía húmeda. Se toma una muestra de polvo después de pasar por los filtros y se compara con la inicial, en una forma cualitativa y cuantitativa, mediante gravimetría y difracción laser. Analizados los resultados, se ha observado una variabilidad significativa en la eficiencia de máscaras y filtros pertenecientes a una misma categoría, por lo que se han sugerido recomendaciones a la normativa actual.

Definition of masks related to psychovisual features for video quality assessment

Video Quality Assessment needs to correspond to human perception. Pixel-based metrics (PSNR or MSE) fail in many circumstances for not taking into account the spatio-temporal property of human's visual perception. In this paper we propose a new pixel-weighted method to improve video quality metrics for artifacts evaluation. The method applies a psychovisual model based on motion, level of detail, pixel location and the appearance of human faces, which approximate the quality to the human eye's response. Subjective tests were developed to adjust the psychovisual model for demonstrating the noticeable improvement of an algorithm when weighting the pixels according to the factors analyzed instead of treating them equally. The analysis developed demonstrates the necessity of models adapted to the specific visualization of contents and the model presents an advance in quality to be applied over sequences when a determined artifact is analyzed.
