The Symbolical Realm and Historical Framework of the Contrade
2017
The chapter describes the contemporary symbolism of the contrade and its historic development in order to allow the reader to follow the subsequent analysis of the content of the contrade’s websites, in which symbols play a key role. It suggests that the contrade of Siena make significant use of mediaeval and Renaissance signs and symbol s such as particular colours, flags, and instruments. Members of a contrada build a community based on a specific district of Siena, and their lives are heavily focused on what is deemed necessary to the win a horse race called palio .
Pictorial meaning-making in a community project in Helsinki. Freirean interpretations of a dialogical process
2018
Participation in public discourse belongs to a democratic citizenship. However, part of the population is excluded from such communal discussion. This paper describes how the photography group Camera Obs., which principally contained unemployed people in Helsinki, created pictorial voices from their own everyday experiences through a dialogical process, rendering them also visible to other people. The research focuses on the group’s activity during the years 2004–6, from the beginning of the project to its first exhibition. As a theoretical background, Paulo Freire’s ideas of dialogue and voice creation, combined with Vygotsky’s and Mezirow’s concept of meaning-making, have been applied. T…
Bajarse al moro en modo travelling. Hacia una caracterización interdiscursiva de la competencia comunicativa audiovisual
2018
Las últimas aportaciones en el desarrollo teórico de la competencia comunicativa audiovisual destacan la idoneidad de diseñar secuencias de enseñanza-aprendizaje en las que se propicie un enfoque metodológico basado en el contraste entre diferentes versiones de una misma producción artística. Partiendo, pues, de estas premisas teóricas, este estudio pretende contribuir al desarrollo de la competencia comunicativa audiovisual mediante el diseño de una secuencia didáctica sobre la obra teatral Bajarse al moro. Con ello se persigue ofrecer un camino metodológico singular en el marco de las enseñanzas medias y universitarias. The design of didactic sequences in which it promotes a methological …
Representação visual de custos no processo produtivo: estudo de caso em uma indústria calçadista de Portugal
2015
Ao longo das últimas décadas, os sistemas convencionais de produção passaram por mudanças diante da intensificação da competitividade entre empresas. As ocorrências dessas mudanças impulsionaram o desenvolvimento de ferramentas de auxílio à tomada de decisão para sistemas produtivos, no entanto, a maioria destes instrumentos não permite a visualização dos custos envolvidos ao longo das operações industriais. O presente estudo realiza a integração do Waste Identification Diagrams (WID), atual ferramenta para visualização e análise de processos produtivos, em conjunto com Time-Driven Activity-Based Costing (TDABC), ferramenta de gestão estratégica de custos, e procura criar um modelo que visu…
Effectiveness of Self-Hypnosis on the Relief of Experimental Dental Pain: A Randomized Trial.
2016
This randomized, controlled clinical trial evaluates the effectiveness of self-hypnosis on pain perception. Pain thresholds were measured, and a targeted, standardized pain stimulus was created by electrical stimulation of the dental pulp of an upper anterior tooth. Pain stimulus was rated by a visual analogue scale (VAS). The pain threshold under self-hypnosis was higher (57.1 ± 17.1) than without hypnotic intervention (39.5 ± 11.8) (p < .001). Pain was rated lower on the VAS with self-hypnosis (4.0 ± 3.8) than in the basal condition without self-hypnosis (7.1 ± 2.7) (p < .001). Self-hypnosis can be used in clinical practice as an adjunct to the gold standard of local anesthesia for pain m…
Zinc isotope variations in archeological human teeth (Lapa do Santo, Brazil) reveal dietary transitions in childhood and no contamination from gloves
2020
International audience; Zinc (Zn) isotope ratios of dental enamel are a promising tracer for dietary reconstruction in archeology, but its use is still in its infancy. A recent study demonstrated a high risk of Zn contamination from nitrile, and latex gloves used during chemical sample preparation. Here we assess the potential impact of the use of such gloves during enamel sampling on the Zn isotope composition of teeth from a population of early Holocene hunter gatherers from Lapa do Santo, Lagoa Santa, Minas Gerais, Brazil. We first examined the amount of Zn and its isotopic composition released from the gloves used in this study by soaking them in weak nitric acid and water. We compared …
Microwave response properties of epoxy resin composites filled with graphitic fillers
2014
Composite materials based on epoxy resin filled with various kinds of graphite particles: exfoliated graphite (EG), natural graphite, and coarse, medium and fine artificial graphites have been prepared. The dielectric permittivity strongly increases with graphite particle size. This effect is related to the distance of the investigated filler concentrations to the composites' percolation threshold. Microwave experiments show that exfoliated graphite is, out of investigated graphite particles, the only one being a really effective additive for producing electromagnetic (EM) interference (EMI) shielding: 2 wt.% epoxy/EG is absolutely opaque to electromagnetic radiation at 30 GHz.
Preparation and characterisation of Ce:YAG -polycarbonate composites for white LED
2016
Ce:YAG-polycarbonate composites were prepared with several amounts of Ce:YAG in the range 0.1-5 wt.% by using melt compounding. The structure and morphology of the composites were investigated by means of X-ray diffractometry and transmission electron microscopy. The optical properties of the composites were studied by using photoluminescence spectroscopy. The intermolecular interaction between the polymer and the filler surface was investigated using 13C cross-polarization magic-angle spinning NMR spectroscopy (13C {1H} CP-MAS NMR). The results showed that the dispersion of the particles in the polymer, and the optical properties, depend on the Ce:YAG amount. The composites were combined w…
Marginal integrity of low-shrinkage and methacrylate-based composite resins: Effect of three different hemostatic agents.
2015
Background: Moisture control is very important in restorative procedures in dentistry. Use of hemostatic agents helps control moisture; however, they might result in changes on enamel and dentin surfaces, affecting composite resin bond quality. The aim of this in vitro study was to evaluate the marginal microleakage of two different composite resins with the use of three different hemostatic agents. Material and Methods: Standardized Class V cavities were prepared on the buccal and lingual surfaces of 48 premolars with cervical margins 1 mm apical to the cementoenamel junction (CEJ). The samples were randomly divided into 8 groups. In groups 1 to 4, an etch-and-rinse adhesive (Adper Single …
A Comprehensive Thermogravimetric Analysis Multifaceted Method for the Exact Determination of the Composition of Multifunctional Metal‐Organic Framew…
2020
Thermogravimetric analysis (TGA) has been widely used as a tool to characterise the composition of materials such as Metal-Organic Frameworks (MOFs). However, given their multifunctionality and structural complexity, examples of detailed methodologies for the exact calculation of the composition of complex MOF structures and MOF composites are lacking in the literature. Herein, we introduce a new straightforward methodology – based on the experimental ratio between the mass of a structure and its residue – for the exact calculation of the composition of almost any MOF material. We provide a detailed guide for the application of our methodology to different MOF materials, including MOFs in w…
