Cenografia teatral: uma análise dos aspectos cênicos da peça Bê-a-Bá Brasil - memória, sonho e fantasia

The main objective of this project step is the evolution of scenery matter on the occidental theater media, related to space and technical possibilities of the theatrical building and space on history of contemporary arts. The main point is that scenery must communicate with a specific matter. Something in touch with the plot speeches. Something that makes all the plot elements to communicate. Acting has an specific message to deliver, and that message is what really matter to the viewer of the show. “It’s never late to state that scenery is not a decoration, or just an interior composition. Scenery is not a painting or a sculpture: it’s an integrated art form. It’s never too repetitive to say that scenery is a result from the composition with lights, shadows, shapes, lines and volumes, in balance and on harmony as a whole, that create movement and contrast” (Dias, 2001) On the second step of the project, the objective is to analyze the building process and the scenery aspects of the “Be-a-bá Brasil” show, using illustrations, pictures and analysis data of the context the show was inserted on

O uso místico da jóia: amuletos de proteção infantil no s��culo XVII

Since the beginning of time man has used body ornaments, often-simple element of decoration, passing by the object ritualistic and religious icon, also as a symbol to the demonstration of status and power. Many of these objects have survived to today, but the vast majority is lost in time or was dismantled to reuse the material in new jewelry. The history of jewelry uses the pieces that have survived intact, documents and images of those jewels. This work uses of Visual Arts, more specifically the portrait art of, to analyze the mystical amulets of child`s protection jewel in works of painters Juan Pantoja dela Cruz and Diego Velásquez.

Origamic design: uma nova forma de desenvolver produtos

During a long time, origami was associated with decoration and craft production of ornaments and figures. However, in the end of 20th century, it began to be studied by mathematicians who were looking for interrelationships between this art and science. Through disciplines like geometry, trigonometry, calculation and linear algebra, they generated a set of axioms and theorems that became possible specific conversion of origami in computational geometry and the development of several softwares. Thus, origami began to be applied in engineering and design studies of innovative product and the term “origamics��� was created to demonstrate its interdisciplinary nature. In this article will be presented some works exploring the constructive principles of origami to contribute with the diffusion of origamics. In this way more professionals will be able to understand the scientific and technological potential of this art.

Les ornements dans l'architecture: comment préserver la mémoire du travail des artisans et des artists

This paper deals with one aspecto f a survey which has been carried out for my doctorate thesis, and with parto f what I have studied within the thematic Project FAPESP concerning the presence of foreign professional in S��o Paulo, coordinated by Prof. Dr. Ana Lúcia Duarte Lanna, between 2007 and 2011. My purpose is, starting from those thoughts , top ut in evidence the potential of sources and reports relating to the work porocesses of craftsmen and artists decorators linked with the environment of architectural practeces and the decoration of interiors in the first half of the XXth century. That preoccupation has accompanied me since the beginnings of my doctorate work, devoted to the study of the production, the circulation and the modes of appropriation of ornaments in teh field of architecture.

Studio analitico della cultura materiale fra VII e IX secolo d.C. nella Regione di Samarcanda (Uzbekistan): analisi morfo-tipologica, produzione e commercio della ceramica di Kafir Kala

Kafir Kala is a key-site to understand the historical dynamics of the Samarkand Region in the Early Middle Ages (5th - 8th centuries CE). The site is clearly associated with a Sogdian occupation, as both literature and archaeological research testify. But the chronological phase that follows the Sogdian period, as the Islamic occupation became stable, is still little known. Structures and finds (an hoard of 133 silver coins, in particular) clearly testify a new occupation of some parts of the citadel; and some rooms, dug in the northern side of it, present structures and materials connected with an Islamic activity. The study of material culture from these rooms, and from more ancient contexts, will help to understand the eventual continuity of traditions and the new productions. Besides the citadel, as a matter of fact, also some kilns have been dug, near the main site. Their material culture is very interesting because it represents an example of the typical Sogdian production (ceramics covered with white mica, and stamped). The work on the ceramic material has consisted in cataloguing and classifying all the diagnostics. Three main morphological classes have been individuated: cooking, coarse and table ware), and some other ones (lamps, ossuaries). A catalogue of the finds organized them in a typological system based on their morphology, function, fabric, and eventually decoration style. Crossing the stratigraphical data with information from this typological study, it has been possible to provide a chronological arrangement of the sites investigated by the italo-uzbek archaeological mission from 2001 to 2008.

La città di Trento tra Tardo Antico e Alto Medio Evo: la genesi della città medievale e lo spazio del sacro.

Lo scavo della chiesa di Santa MAria Maggiore ha permesso di acquisire nuove importanti informazioni sulla storia della città di Trento, sulla città tardo antica e sul processo di cristianizzazione. Il primo impianto ecclesiastico, datato a dopo la metà del V d. C. secolo, sorge su un precedente impianto termale realizzato intorno al II secolo d. C. ed appare caratterizzato da un forte carattere monumentale. La chiesa, a tre navate, presentava un presbiterio rialzato decorato in una prima fase da un opus sectile poi sostituito nel VI secolo da un mosaico policromo. Sono state rinvenute inoltre, parti consistenti della decorazione architettonica di fine VIII secolo pertinente questo stesso impianto che non subirà importanti modifiche fino alla realizzazione del successivo edificio di culto medievale, meno esteso e dai caratteri decisamente meno monumentali, caratterizzato dalla presenza di un esteso campo cimiteriale rinvenuto a nord della chiesa. A questo impianto ne succede un terzo, probabilmente a due navate, e dalla ricca decorazione pittorica demolito in età tardo rinascimentale per la realizzazione della chiesa attuale.

La committenza artistica dei Templari e degli Ospitalieri in Emilia Romagna

La tesi di dottorato La committenza artistica dei Templari e degli Ospitalieri in Emilia Romagna cerca attraverso un approccio metodologico multidisciplinare di ricostruire il patrimonio artistico delle commende dei due ordini religioso cavallereschi in regione. La tesi è stata concepita per riflettere anche a livello strutturale la metodologia d’indagine, cos�� un primo capitolo è dedicato all’analisi storica dei due ordini, con particolare attenzione alla comprensione del rapporto tra gli ordini e il mondo dell’arte. Una secondo capitolo invece è incentrato sulla storiografia artistica relativa e sulle impegnative indagini d’archivio, che, soprattutto attraverso l’utilizzo di una vasta documentazione inedita, hanno permesso di fornire nuovi elementi alla definizione della rete degli insediamenti e della loro decorazione. Lo studio prosegue con la specifica ricostruzione storica e storico artistica delle commende attraverso l’indagine sui singoli insediamenti, dove si è cercato di dar conto delle vicende artistiche e della storia dei suoi protagonisti. Contestualmente alla redazione di questo capitolo, riconoscendo la storia, il senso e l’importanza della scuola stilistico-filologica, si procede alla redazione delle schede di catalogo delle opere superstiti, sia di quelle ancora nelle ex-commende sia di quelle che oggi hanno altre collocazioni. Successivamente, senza necessariamente trarre conclusioni definitive su un lavoro di ricerca che per sua natura è in divenire, si argomentano alcune riflessioni sulla natura, i limiti, i caratteri e l’evoluzione della committenza dei due ordini cavallereschi in regione. Si è cos�� riscoperto un patrimonio artistico vasto e articolato che coniuga capolavori con opere di cultura assai più corsiva, ma comunque sempre capace di raccontare la storia dei suoi artefici (alcuni - come Aristotele Fioravanti, Girolamo da Treviso, Pietro Bembo o Ranuccio Farnese - veri e propri protagonisti del loro tempo), in continuo e sostanziale dialogo con le culture artistiche che hanno attraversato la regione, e non solo, tra Medioevo e Modernità.

Optical resonances of sphere-on-plane geometries

The optical resonances of metallic nanoparticles placed at nanometer distances from a metal plane were investigated. At certain wavelengths, these “sphere-on-plane” systems become resonant with the incident electromagnetic field and huge enhancements of the field are predicted localized in the small gaps created between the nanoparticle and the plane. An experimental architecture to fabricate sphere-on-plane systems was successfully achieved in which in addition to the commonly used alkanethiols, polyphenylene dendrimers were used as molecular spacers to separate the metallic nanoparticles from the metal planes. They allow for a defined nanoparticle-plane separation and some often are functionalized with a chromophore core which is therefore positioned exactly in the gap. The metal planes used in the system architecture consisted of evaporated thin films of gold or silver. Evaporated gold or silver films have a smooth interface with their substrate and a rougher top surface. To investigate the influence of surface roughness on the optical response of such a film, two gold films were prepared with a smooth and a rough side which were as similar as possible. Surface plasmons were excited in Kretschmann configuration both on the rough and on the smooth side. Their reflectivity could be well modeled by a single gold film for each individual measurement. The film has to be modeled as two layers with significantly different optical constants. The smooth side, although polycrystalline, had an optical response that was very similar to a monocrystalline surface while for the rough side the standard response of evaporated gold is retrieved. For investigations on thin non-absorbing dielectric films though, this heterogeneity introduces only a negligible error. To determine the resonant wavelength of the sphere-on-plane systems a strategy was developed which is based on multi-wavelength surface plasmon spectroscopy experiments in Kretschmann-configuration. The resonant behavior of the system lead to characteristic changes in the surface plasmon dispersion. A quantitative analysis was performed by calculating the polarisability per unit area /A treating the sphere-on-plane systems as an effective layer. This approach completely avoids the ambiguity in the determination of thickness and optical response of thin films in surface plasmon spectroscopy. Equal area densities of polarisable units yielded identical response irrespective of the thickness of the layer they are distributed in. The parameter range where the evaluation of surface plasmon data in terms of /A is applicable was determined for a typical experimental situation. It was shown that this analysis yields reasonable quantitative agreement with a simple theoretical model of the sphere-on-plane resonators and reproduces the results from standard extinction experiments having a higher information content and significantly increased signal-to-noise ratio. With the objective to acquire a better quantitative understanding of the dependence of the resonance wavelength on the geometry of the sphere-on-plane systems, different systems were fabricated in which the gold nanoparticle size, type of spacer and ambient medium were varied and the resonance wavelength of the system was determined. The gold nanoparticle radius was varied in the range from 10 nm to 80 nm. It could be shown that the polyphenylene dendrimers can be used as molecular spacers to fabricate systems which support gap resonances. The resonance wavelength of the systems could be tuned in the optical region between 550 nm and 800 nm. Based on a simple analytical model, a quantitative analysis was developed to relate the systems��� geometry with the resonant wavelength and surprisingly good agreement of this simple model with the experiment without any adjustable parameters was found. The key feature ascribed to sphere-on-plane systems is a very large electromagnetic field localized in volumes in the nanometer range. Experiments towards a quantitative understanding of the field enhancements taking place in the gap of the sphere-on-plane systems were done by monitoring the increase in fluorescence of a metal-supported monolayer of a dye-loaded dendrimer upon decoration of the surface with nanoparticles. The metal used (gold and silver), the colloid mean size and the surface roughness were varied. Large silver crystallites on evaporated silver surfaces lead to the most pronounced fluorescence enhancements in the order of 104. They constitute a very promising sample architecture for the study of field enhancements.

Multicomponent nanodevices based on molecular and nanocrystal moieties

Nanoscience is an emerging and fast-growing field of science with the aim of manipulating nanometric objects with dimension below 100 nm. Top down approach is currently used to build these type of architectures (e.g microchips). The miniaturization process cannot proceed indefinitely due to physical and technical limitations. Those limits are focusing the interest on the bottom-up approach and construction of nano-objects starting from “nano-bricks��� like atoms, molecules or nanocrystals. Unlike atoms, molecules can be “fully programmable” and represent the best choice to build up nanostructures. In the past twenty years many examples of functional nano-devices able to perform simple actions have been reported. Nanocrystals which are often considered simply nanostructured materials, can be active part in the development of those nano-devices, in combination with functional molecules. The object of this dissertation is the photophysical and photochemical investigation of nano-objects bearing molecules and semiconductor nanocrystals (QDs) as components. The first part focuses on the characterization of a bistable rotaxane. This study, in collaboration with the group of Prof. J.F. Stoddart (Northwestern University, Evanston, Illinois, USA) who made the synthesis of the compounds, shows the ability of this artificial machine to operate as bistable molecular-level memory under kinetic control. The second part concerns the study of the surface properties of luminescent semiconductor nanocrystals (QDs) and in particular the effect of acid and base on the spectroscopical properties of those nanoparticles. In this section is also reported the work carried out in the laboratory of Prof H. Mattoussi (Florida State University, Tallahassee, Florida, USA), where I developed a novel method for the surface decoration of QDs with lipoic acid-based ligands involving the photoreduction of the di-thiolane moiety.

Alpha, Omega end group functionalization of RAFT polymers based on pentafluorophenyl esters and methane thiosulfonates

While polymers with different functional groups along the backbone have intensively been investigated, there is still a challenge in orthogonal functionalization of the end groups. Such well-defined systems are interesting for the preparation of multiblock (co) polymers or polymer networks, for bio-conjugation or as model systems for examining the end group separation of isolated polymer chains. rnHere, Reversible Addition Fragmentation Chain Transfer (RAFT) polymerization was employed as method to investigate improved techniques for an a, w end group functionalization. RAFT produces polymers terminated in an R group and a dithioester-Z group, where R and Z stem from a suitable chain transfer agent (CTA). rnFor alpha end group functionalization, a CTA with an activated pentafluorophenyl (PFP) ester R group was designed and used for the polymerization of various methacrylate monomers, N-isopropylacrylamide and styrene yielding polymers with a PFP ester as a end group. This allowed the introduction of inert propyl amides, of light responsive diazo compounds, of the dyes NBD, Texas Red, or Oregon Green, of the hormone thyroxin and allowed the formation of multiblocks or peptide conjugates. rnFor w end group functionalization, problems of other techniques were overcome through an aminolysis of the dithioester in the presence of a functional methane thiosulfonate (MTS), yielding functional disulfides. These disulfides were stable under ambient conditions and could be cleaved on demand. Using MTS chemistry, terminal methyl disulfides (enabling self-assembly on planar gold surfaces and ligand substitution on gold and semiconductor nanoparticles), butynyl disulfide end groups (allowing the “clicking” of the polymers onto azide functionalized surfaces and the selective removal through reduction), the bio-target biotin, and the fluorescent dye Texas Red were introduced into polymers. rnThe alpha PFP amidation could be performed under mild conditions, without substantial loss of DTE. This way, a step-wise synthesis produced polymers with two functional end groups in very high yields. rnAs examples, polymers with an anchor group for both gold nanoparticles (AuNP) and CdSe / ZnS semi-conductor nanoparticles (QD) and with a fluorescent dye end group were synthesized. They allowed a NP decoration and enabled an energy transfer from QD to dye or from dye to AuNP. Water-soluble polymers were prepared with two different bio-target end groups, each capable of selectively recognizing and binding a certain protein. The immobilization of protein-polymer-protein layers on planar gold surfaces was monitored by surface plasmon resonance.Introducing two different fluorescent dye end groups enabled an energy transfer between the end groups of isolated polymer chains and created the possibility to monitor the behavior of single polymer chains during a chain collapse. rnThe versatility of the synthetic technique is very promising for applications beyond this work.
