Do Largo das Mercês à Praça Visconde do Rio Branco: um estudo de gestão do patrimônio histórico em Belém do Pará, 1941-2011

Do Largo das Mercês à Praça Visconde do Rio Branco: um estudo de gestão do patrimônio Histórico em Belém do Pará, 1941-2011, propõe a realização de uma análise da gestão dos órgãos de preservação à nível municipal, estadual e federal na cidade de Belém, a partir de um estudo sobre a praça e entorno imediato, verificando as condições de caracterização e de conservação deste conjunto arquitetônico, urbanístico e paisagístico, desde a década de 1940 até os dias atuais. A linguagem visual desta dissertação também ajuda na observação das alterações ocorridas na praça e nos imóveis que a delimitam, posto que a imagem fotográfica constitui-se em importante instrumento de investigação histórica, para identificar novos objetos e novos problemas, além de indicar aqueles que permanecem ao longo dos anos. Pretende-se analisar alguns dos projetos já desenvolvidos para a área, com base nos respectivos tombamentos existentes no Centro Histórico da cidade. Espera-se, dessa forma, poder verificar e analisar as ações de proteção realizadas pelos órgãos responsáveis pela salvaguarda do patrimônio cultural, verificando se existe compatibilidade de critérios e de ações. Este estudo procura, também, diagnosticar os problemas atuais da praça e ressaltar a importância de sua manutenção, para a memória histórica e arquitetônica de Belém.

It identifies the proportion of books for children in Brazil using the photographic image, as well as what categories of books are applied. Elaborates an analytical discussion based on the example of the book Quadrille by Roger Mello, arguing about some characteristics of the use of the photographic image in the literature aimed at children.

Estudio de las formas de aplicación de la fotografía sobre los materiales pétreos para la arquitectura = Study of photography application methods over architectural stony materials

Desde que el Hombre era morador de las cavernas ha sido manifiesto su deseo innato por grabar y reproducir "instantáneas con las que perpetuarse o sobre las que mirarse ". La aparición y desarrollo de la fotografía como medio para poder captar y fijar "la imagen directa de la realidad circundante " pronto se convierte en un nuevo lenguaje estético y poético que permite al artista la interpretación y reflexión de lo observado. Se imprime a la imagen el carácter de la mirada del fotógrafo, estableciendo un diálogo conceptual con el juego de luces. La presente Tesis plantea la creación de una nueva piel de arquitectura mediante la impresión fotográfica sobre materiales pétreos. La búsqueda de la expresividad de los materiales como soporte de expresión artística implica un cambio de escala al trasladar la instantánea fotográfica a la arquitectura y la aplicación de un nuevo soporte al imprimir la fotografía sobre materiales arquitectónicos. Se justifica la elección del dispositivo láser CO2 como sistema de impresión fotográfica sobre los materiales pétreos arquitectónicos, como la técnica que permite la unión física de la imagen y el proyecto arquitectónico, generando un valor añadido a través del arte de la fotografía. Se justifica la elección de los materiales investigados, Silestone® Blanco Zeus y GRC® con TX Active® Aria, de forma que la investigación de esta nueva piel de arquitectura abarca tanto la envolvente del edificio como su volumen interior, permitiendo cerrar el círculo arquitectónico "in&out" y dota al proyecto arquitectónico de un valor añadido al introducir conceptos sostenibles de carácter estético y medioambiental. Se realiza una consulta a las empresas del sector arquitectónico relacionadas directamente con la producción y distribución de los materiales Silestone® y GRC®, así como a las empresas especializadas en sistemas de impresión fotográfica sobre materiales, acerca del estado del arte. Se recorre la Historia de la fotografía desde sus orígenes hasta el desarrollo de la era digital y se analiza su condición artística. Se recopilan los sistemas de impresión fotográfica que han evolucionado en paralelo con los dispositivos de captura de la instantánea fotográfica y se describe en profundidad el sistema de impresión fotográfica mediante dispositivo láser CO2. Se describen los procesos de fabricación, las características técnicas, cualidades y aplicaciones de los materiales pétreos arquitectónicos Silestone® Blanco Zeus y GRC® con TX Active® Aria. Se explica la técnica utilizada para la captación de la imagen fotográfica, su justificación artística y su proceso de impresión mediante dispositivo láser CO2 bajo diferentes parámetros sobre muestras de los materiales arquitectónicos investigados. Se comprueba la viabilidad de desarrollo de la nueva piel de arquitectura sobre Silestone® Blanco Zeus y GRC® con TX Active® Aria sometiendo a las piezas impresas bajo diferentes parámetros a tres ensayos de laboratorio. En cada uno de ellos se concreta el objetivo y procedimiento del ensayo, la enumeración de las muestras ensayadas y los parámetros bajo los que han sido impresas, el análisis de los resultados del ensayo y las conclusiones del ensayo. Ensayo de amplitud térmica. Se determina el grado de afectación de las imágenes impresas bajo la acción de contrastes térmicos. Series de muestras de Silestone® Blanco Zeus y GRC® con TX Active® Aria impresas con láser CO2 se someten a ciclos de contraste frío-calor de 12 horas de duración para una amplitud térmica total de 102°C. Se realiza una toma sistemática de fotografías microscópicas con lupa de aumento de cada pieza antes y después de los ciclos frío-calor y la observación de las transformaciones que experimentan los materiales bajo la acción del láser CO2. Ensayo de exposición a la acción de la radiación ultravioleta (UV). Se determina el grado de afectación de las imágenes impresas al activar la capacidad autolimpiante de partículas orgánicas. Una serie de muestras de GRC® con TX Active® Aria impresa con láser CO2 se someten a ciclos de exposición de radiación ultravioleta de 26 horas de duración. Se somete la serie a un procedimiento de activación del aditivo TX Active®. Se simula la contaminación orgánica mediante la aplicación controlada de Rodamina B, tinte orgánico, y se simula la radiación UV mediante el empleo de una bombilla de emisión de rayos ultravioleta. Se realiza una toma sistemática de fotografías macroscópicas de la serie de muestras ensayadas: antes de aplicación de la Rodamina B, momento 00:00h, momento 04:00h y momento 26:00h del ensayo. Se procede a la descarga y análisis del histograma de las fotografías como registro de la actividad fotocatalítica. Ensayo de la capacidad autodescontaminante del GRC® con TX Active® impreso con láser CO2. Se comprueba si la capacidad autodescontaminante del GRC® con TX Active® se ve alterada como consecuencia de la impresión de la imagen fotográfica impresa con láser CO2. Serie de muestras de GRC® con TX Active® Aria impresa con láser CO2 se someten a test de capacidad autodescontaminante: atmósfera controlada y contaminada con óxidos de nitrógeno en los que se coloca cada pieza ensayada bajo la acción de una lámpara de emisión de radiación ultravioleta (UV). Se registra la actividad fotocatalítica en base a la variación de concentración de óxido de nitrógeno. Se recopila el análisis e interpretación de los resultados de los ensayos de laboratorio y se elaboran las conclusiones generales de la investigación. Se sintetizan las futuras líneas de investigación que, a partir de las investigaciones realizadas y de sus conclusiones generales, podrían desarrollarse en el ámbito de la impresión fotográfica sobre materiales arquitectónicos. Se describe el rendimiento tecnológico y artístico generado por las investigaciones previas que han dado origen y desarrollo a la Tesis Doctoral. ABSTRACT Since ancient time, humanity has been driven by an innate wish to reproduce and engrave "snapshots that could help to perpetúate or to look at one self". Photography's birth and its development as a mean to capture and fix "the direct image of the surrounding reality" quickly becomes a new aesthetical and poetical language allowing the artist to interpret and think over what has been observed. The photographer's eye is imprinted onto the image, and so the conceptual dialogue between the artist and the light beams begins. The current thesis suggests the creation of a new architectural skin through photography imprinting over stony materials. The search for material's expressiveness as a medium of artistic expression involves a change of scale as it transfers photographic snapshot into architecture and the use of a new photographic printing support over architectural materials. CO2 laser is the chosen printing system for this technique as it allows the physical union of the image and the architectonic project, generating an added value through the art of photography. The researched materials selected were Silestone®, Blanco Zeus and GRC® with TX Active® Aria. This new architectural skin contains the building surrounding as well as its interior volume, closing the architectonic "in & out" circle and adding a value to the project by introducing aesthetical and environmental sustainable concepts. Architecture companies related to the production and distribution of materials like Silestone® and GRC®, as well as companies specialized in photography printing over materials were consulted to obtain a State of the Art. A thorough analysis of photography's History from its origins to the digital era development was made and its artistic condition was studied in this thesis. In this study the author also makes a compilation of several photographic printing systems that evolved together with photographic snapshot devices. The CO2 laser-based photographic printing system is also described in depth. Regarding stony materials of architecture like Silestone®, Blanco Zeus and GRC® with TX Active® Aria, the present study also describes their manufacture processes as well as technical features, quality and application. There is also an explanation about the technique to capture the photographic image, its artistic justification and its CO2 laser-based printing system over the researched materials under different parameters. We also tested the feasibility of this new architectural skin over Silestone® Blanco Zeus and GRC® with TX Active® Aria. The pieces were tested under different parameters in three laboratory trials. Each trial comprises of an explanation of its objective and its process, the samples were numbered and the printing parameters were specified. Finally, with the analysis of the results some conclusions were drawn. In the thermal amplitude trial we tried to determine how printed images were affected as a result of the action of thermal contrasts. Series of samples of Silestone® Blanco Zeus and GRC® with TX Active® Aria printed with CO2 laser were subjected to several 12h warm-cold cycles for thermal total amplitude of 102oc. Each sample was captured systematically with microscopic enhanced lenses before and after cold-warm cycles. The changes experienced by these materials under the effect of CO2 laser were observed and recorded. Trial regarding the Ultraviolet Radiation (UR) effect on images. We determined to which extent printed images were affected once the self-cleaning organic particles were activated. This time GRC® with TX Active® Aria samples printed with CO2 laser were exposed to a 26h UR cycle. The samples were subjected to the activation of TX Active® additive. Through the controlled application of Rodamine B and organic dye we were able to simulate the organic contamination process. UR was simulated using an ultraviolet beam emission bulb. A systematic capture of macroscopic pictures of the tested sample series was performed at different time points: before Rodamine B application, at moment 00:00h, moment 04:00h and moment 26:00h of the trial. Picture's histogram was downloaded and analyzed as a log of photocatalytic activity. Trial regarding the self-decontaminating ability of GRC® with TX Active® printed with CO2 laser. We tested if this self-decontaminating ability is altered as a result of CO2 laser printed image. GRC® with TX Active® Aria samples printed with CO2 laser, were subject to self-decontaminating ability tests with controlled and nitrogen oxide contaminated atmosphere. Each piece was put under the action of an UR emission lamp. Photocatalytic activity was recorded according to the variation in nitrogen oxide concentration. The results of the trial and their interpretation as well as the general conclusions of the research are also compiled in the present study. Study conclusions enable to draw future research lines of potential applications of photographic printing over architecture materials. Previous research generated an artistic and technological outcome that led to the development of this doctoral thesis.

La casa en imágenes : pulsos, ecos y huellas del habitar contemporáneo

La imagen fotográfica es un bloque espacio tiempo congelado, un fragmento referido al antes y el después de algo. Al contemplar una fotografía de un interior doméstico, descubrimos un entretejido sutil entre el habitante y su hábitat. Somos capaces de recaer en más detalles de los que el ojo humano puede apreciar en su visión cotidiana, siempre ligada al devenir espacio temporal. El acto de fotografiar el hogar, de congelar unidades habitadas infinitesimales, se revela como una manifestación radical del modo unipersonal de habitar de cada fotógrafo, profesional o aficionado, y por extensión, dado que hoy todos somos fotógrafos; de cada habitante. Por un lado, la fotografía se piensa aquí como herramienta, capaz de desvelar, de poner en el mundo, los elementos, percepciones y acontecimientos, que subyacen imbricados en la construcción del hogar. Por otro, la imagen se entiende como medio de expresión y de comunicación, como el lenguaje universal de nuestro tiempo, por todos conocido y utilizado. En este momento de interconexión máxima, entre redes, datos y capas de cognición, de velocidad y aceleración, esta tesis doctoral se plantea como una vuelta a la reflexión, a la contemplación del objeto imagen, desde la certeza de que para que ésta hable hay que darle tiempo. Así, la investigación hay que entenderla desde una base ontológica y fenomenológica; desde la experiencia del ser que habita un entorno concreto y determinado. Se enmarca en el actual entorno socio cultural de occidente, se busca desvelar el significado y modo de habitar del habitante común, poniendo de manifiesto aquello que acontece para que una casa cualquiera, de un habitante cualquiera, devenga hogar. Los primeros indicios sobre el tema surgirán del análisis y la reinterpretación hermenéutica de un atlas de imágenes del habitar: cuerpo de imágenes reunido a partir de series fotográficas de hogares, de habitantes anónimos, puestos a luz por la mirada de un grupo de artistas. Posteriormente, ponemos a prueba el conocimiento adquirido en el análisis anterior, mientras que expandimos la investigación hacia el sentir del habitante común, mediante la realización de tres experimentos participativos, o estudios de campo cualitativos. Los resultados, de ambos grupos de casos de estudio, se compilan, organizan y estructuran en una taxonomía del habitar. Esta taxonomía está compuesta por cuarenta y siete parámetros, que explicitan la naturaleza compleja del hogar del siglo XXI. Este hogar es entendido como un constructo personal de cada habitante, un proceso que acontece en el tiempo y en el espacio, y que entraña la propia construcción del habitante. Esta extensa taxonomía se organiza según tres ámbitos del ser humano, en el primero se expresan los factores relacionados con el modo de "estar físicamente" en el hogar, incluyendo: al propio habitante, la casa como espacio arquitectónico y como materialidad: objetos, muebles, iconos y símbolos que pueblan el hogar. En segundo lugar, se manifiestan los parámetros relacionados con el modo de “percibir”: por un lado, aquello que se deriva de lo que se ve, y por otro, lo que se deriva de aquello que no se ve, pero se siente. En tercer lugar, se explicitan los factores relativos al habitante que "crea/juega" su hogar, quién por un lado, es en el mundo actuando, y que por otro, siente el mundo construyéndolo mediante una serie de relaciones que establece con él. Finalmente, la investigación intenta revelar las sinergias, conexiones y relaciones, entre todos estos elementos extraídos del sentir del habitante común, y que fueron inducidos mediante el análisis y reinterpretación de los casos de estudio, poniendo de manifiesto un orden de cosas en el habitar occidental contemporáneo. ABSTRACT The photographic image is a frozen space time block, a fragment referred to a something before and after. When we stare at the photography of domestic interiors we discover a subtle interweaving between the inhabitant and her habitat. We are able to acknowledge infinite more details than the human eye, in its continuous quotidian vision always linked to the space time progression, appreciates. The act of photographing the home, of freezing infinitesimal inhabited units, reveals as a radical statement of the concept of inhabiting for each photographer, professional or amateur, and by extension, as we today all are photographers, for each inhabitant. On the one hand, photography is here conceived as a tool that is capable of revealing, "of placing in the world" the elements, perceptions and happenings that underlie imbricated in the construction of a home. On the other hand, image is thought as an expression and communication media, as the universal language of our time (as far as it is known and used by all of us). In this precise moment of maximum interconnection between networks, data and cognitive layers; of speed and acceleration, this PhD Dissertation is conceived as a return to reflection; to the contemplation of object image, from the certainty of its need of time for talking. Therefore, this research from an ontological and phenomenological base; from the experience of the self who inhabits a determined and concrete environment, that of the western countries at the present, pursues to unveil the meaning and way of inhabiting of a common dweller and manifest what conforms the transformation of any house, of any inhabitant into a home. The first clues will arise from the analysis and hermeneutical reinterpretation of the Atlas of inhabiting; an assembled body of images of anonymous inhabitants houses, brought into life through a group of artist´s glance. Afterwards, we will test the analysis´s acquired knowledge, while extending the investigation to the feel of the common inhabitant (and no longer the expert^ artist) through the execution of three participative experiments conceived as qualitative field works. The results of both case study groups, will be compiled, organized and structured in a taxonomy of the inhabiting. This taxonomy is composed by forty seven parameters that explicitly state the complex nature of the XXI century home, regarded as a personal construct of every single inhabitant, as a process that happens through time and space and that entails the construction of the inhabitant. This wide taxonomy is organized regarding three spheres of the human being, In first place, those elements related to the way of “physically being” at home are expressed, including: the inhabitant its self, the house as architectural space and as materiality: objects, furniture, icons and symbols that fill the home. In second place, parameters related to the way of “perceiving“ are manifested; on the one hand, those that derive from what we see; on the other hand, those that derive from what we do not see, but feel. In third place, those factors deriving from the inhabitant as a home "creator/player" who is acting in the world and feeling the world while constructing it through a myriad of relationships he establishes with it. Finally, the investigation tries to reveal the synergies, connections and relations between all these elements extracted from the feelings of the common inhabitant, induced through the analysis and reinterpretation of the case studies, and therefore exposing a state of things belonging to western world at present.

Desejos ilustrados : um resgate à fotopintura

Using the photographic image as a drawing tool we end up uncovering a universe with two dimensions: the technical and the affective. To rescue the technical essence of Photo Painting, to artistically draw with light, is to go through the History of Portrait and to discover the real meaningful existence of the photographic image -since its beginning until its use changed within society. To go back to the origins of the practical techniques is to find a unique language inside this particular universe. The purpose of this dissertation is to work images not only as mere copies or mirrors of reality but as sanctuaries. To do so, I worked on finding meaningful elements within those images to add or subtract other elements. Meaning, by going through the affective element and interacting with it, I was able to find out which practical techniques I would be able to use without hurting or even diminishing other people’s memories. The premise is to provide clues in the investigation in order to make this the first step in a continued research.

Anterior segment anomalies and effects on visual quality

The tear film, cornea and lens dictate the refractive power of the eye and the retinal image quality is principally defined by diffraction, whole eye wavefront error, scatter, and chromatic aberration. Diffraction and wave aberration are fundamentally pupil diameter dependent; however scatter can be induced by refractive surgery and in the normal ageing eye becomes an increasingly important factor defining retinal image quality. The component of visual quality most affected by the tear film, refractive surgery and multifocal contact and intraocular lenses is the wave aberration of the eye. This body of work demonstrates the effects of each of these anomalies on the visual quality of the eye. When assessing normal or borderline self-diagnosed dry eye subjects using aberrometry, combining lubricating eye drops and spray does not offer any benefit over individual products. However, subjects perceive a difference in comfort for all interventions after one hour. Total higher order aberrations increase after laser assisted sub-epithelial keratectomy performed using a solid-state laser on myopes, but this causes no significant decrease in contrast sensitivity or increase in glare disability. Mean sensitivity and reliability indices for perimetry were comparable to pre-surgery results. Multifocal contact lenses and intraocular lenses are designed to maximise vision when the patient is binocular, so any evaluation of the eyes individually is confounded by reduced individual visual acuity and visual quality. Different designs of aspheric multifocal contact lenses do not provide the same level of visual quality. Multifocal contact lenses adversely affect mean deviation values for perimetry and this should be considered when screening individuals with multifocal contact or intraocular lenses. Photographic image quality obtained through a multifocal contact or intraocular lens appears to be unchanged. Future work should evaluate the effect of these anomalies in combination; with the aim of providing the best visual quality possible and supplying normative data for screening purposes.

La suggestion de pistes narratives - Comment évoquer une histoire, un souvenir, un instant en art vidéo

L’essentiel de ce texte se veut une réflexion sur la manière de raconter une histoire ou, plutôt, de l’évoquer : un questionnement qui fonde ma pratique de l’image photographique et vidéographique. Afin de mener à bien cette réflexion, plusieurs aspects de mon questionnement par rapport à l’image seront abordés : la notion de véracité historique, l’image photographique, l’image d’archives, la complexité, un « univers de possibles », ainsi que l’analyse de ma méthodologie de travail. Cet approfondissement théorique sera développé de connivence avec ma pratique visuelle qui, dans le cadre de ma maîtrise en arts visuels, s’est principalement déployée sous la forme de l’installation vidéographique. Mots-clés : histoire, archives, évocation, complexité, art vidéographique.

Presente: um projeto de futuro sobre um passado

PRESENTE é um projecto fotográfico que olha o futuro a partir do instante presente com o objectivo não só de acondicionar um passado, neste caso sobre a Guerra Colonial, mas também com o objectivo de o inocular nas futuras gerações. Nesse sentido considera-se fundamental começar por se reflectir sobre a actual fragilidade da imagem fotográfica, quer enquanto crença quer enquanto construtora de ficções, tanto mais que em qualquer relação que se estabeleça entre objectos animados e objectos não animados, estes se podem inter-relacionar enquanto sistemas simbólicos de representação. Assim esta dissertação propõe a construção de um projecto fotográfico que, através do seu apuro processual, vai explorar a criação de mecanismos de recolha da memória material e imaterial hoje sobrevivente à Guerra Colonial bem como procurar uma forma significativa de a transmitir para o futuro na forma de exposição pública.

Lo fotográfico en la narrativa contemporánea de lengua francesa: P. Modiano, A. Makine y A. Ernaux

The goal of this study is to define the photographic dimension as a transversal notion that accompanies texts and carries out a function that is narrative, discursive and even poetic, and as an unambiguous analytical tool that allows an understanding of the function of the photographic image in contemporary fiction. How does the photographic dimension act within a text of fiction? How does it guide it, define it, and eventually, transform it? How is the space-time element of a text influenced when the photographic dimension affects the heart of the story? How does the status of the photographic image change when it is blended with the fictional text, and how is a text reorganized in light of the photographic dimension? What interpretations are made possible by the analysis of the photographic dimension? Is it possible to narrate and read a photograph without having to see it, or to what extent does a photograph in plain view determine the writing and reading of the story? In short: What writing and reading digressions are caused by the presence of photographs within a literary text; what is their role, for example, in the activation of memory, of a dream-like state or of identity, and what symbolic dimension is introduced?...

Image calibration to like-values in mapping shallow water quality from multitemporal data

The applicability of image calibration to like-values in mapping water quality parameters from multitemporal images is explored, Six sets of water samples were collected at satellite overpasses over Moreton Bay, Brisbane, Australia. Analysis of these samples reveals that waters in this shallow bay are mostly TSS-dominated, even though they are occasionally dominated by chlorophyll as well. Three of the images were calibrated to a reference image based on invariant targets. Predictive models constructed from the reference image were applied to estimating total suspended sediment (TSS) and Secchi depth from another image at a discrepancy of around 35 percent. Application of the predictive model for TSS concentration to another image acquired at a time of different water types resulted in a discrepancy of 152 percent. Therefore, image calibration to like-values could be used to reliably map certain water quality parameters from multitemporal TM images so long as the water type under study remains unchanged. This method is limited in that the mapped results could be rather inaccurate if the water type under study has changed considerably. Thus, the approach needs to be refined in shallow water from multitemporal satellite imagery.

Photographic art and dealing with death

Recently, we were faced with a request from a student photographer who wanted to take pictures of bodies donated to our institute and used for dissection courses for medical students or for scientific purposes. Students are expressly forbidden to take pictures in the dissection hall; however, we allowed this student photographer to do her diploma work in our institute. The reason why she was proposing such a topic was that her brother died young and her parents donated his body to science. To overcome this loss of a loved one, she wanted to know what happens to the donated bodies. She followed the procedure of embalming and different dissections that took place during the summer semester and she took pictures throughout. The outcome of this work was a very nice photographic document, called 'dissection', a book with many pictures but no figure legends. The image document shows the different steps in the preparation and preservation of bodies and the work of an anatomist in the dissection hall. As we impose rules on our students, we had also to give directives in the use of the photographs taken, especially for a photographer who will use the most prominent pictures for exhibitions, i.e. that the pictures do not show names or are used for publication on the internet, or show identification numbers of cadavers, or give indication ofn the institution and are relatively anonymous. This story tells how one can deal with death and at the same time advance one's personal career.
