Um direcionamento às novas tecnologias na arquitetura: habitação de um futuro presente, em um espaço para a vida

This paper tries, across research, books, magazines and charts that relate to the architecture of today, establishing a direction as to the technological advances that may be involved in the architecture project. Such that the configuration space has flexibility to meet the basic architectural principles and the wishes of the user, who should participate as a key character of the decisions of spatialization - interface. Both the personal point of view of their social relations within the housing, and the functional environments equipped and qualified to meet expectations during its use. Respecting the power of free choice of human beings, not to put yourself to the detriment by excessive use of technology. And still look for ways to integrate the individual to society connected to your network - home. Keywords: interface, information, technology, space flexibility

Estudo da gestão de aterros sanitários através de consórcios públicos e públicos-privados

The growing population, purchasing power and changing the profile of Brazilian consumers are the facts to justify the increase in waste production in the country. According to the National Research Sanitation made by IBGE in 2000, Brazil produced 241,614 tons of waste per day, equivalent to approximately 90 million tons per year. This growth leads researchers to consider a better way to dump this material in order to mitigate the damage to population health and the environment. For this, one of the possible actions is the search for alternative disposal technological development, a possible solution being the construction of landfills. But many cities, especially those from regions of poor or agricultural base, do not always have sufficient resources and open spaces for the construction of a landfill as required by law. Fits like a context in which it operates as an alternative technology for inter-municipal consortia landfill and public-private partnerships in order to contribute to the sustainable development of cities. The law that regulates public consortia is the Federal Law 11.107 of April 2005, as the law that regulates and makes possible the Public-Private Partnership is the Federal Law 11.079 of 2004. Consortia are entities that bring together several municipalities, with or without the State and the Union to carry out joint actions that if were borne singly, not would achieve the same results or would lose a greater volume of resources, and would demand more time. The public-private partnership consist of one or more municipalities and a private company, selected by public tender, which becomes responsible for implementation, maintenance and operation of the landfill. This practice can performed on the model of concession, in which public administration is direct or indirect user, with or without installation and ...

Protagonismo politico e social na velhice: cenários, potencias e problemáticas

The active presence of the old ones in the society brings up discussions about the political and social participation in the advanced ages of the life. The senior citizen, like an actor of great relevance in the present time, shows their potential as scriptwriter and protagonist of their own history. However, many spaces constituted vertically, turned for this aim become artificial, abolishing, many times, the spontaneity and potential of these actors. Anyway, the important thing is to open spaces for the different expressions of social participation and that they find their legitimacy and place in the set of the protagonism that attaches life and sense to the world.

The affective-emotional communication in shoppingscapes: case study

Shoppingscapes on urban roads, such as streets and avenues, require study and more specific attention. You must be aware of the emotional communication, an important factor with regard to the influence on the perception and acquisition process by the observer. Reaching the consumer cognitively, arousing emotion and desire to want to have the observed object is one of the goals of emotional communication, and that only happens with the proper use of elements of perception. This paper aims to highlight the need for interdisciplinary design and architecture, especially in the case of shoppingscapes in open spaces that sell fashion items. The case study raises a reflection on the elements of perception in the windows as to whether they are being clearly communicated. It also discusses how the same are interfering or being interfered by the shoppingscapes of Avenida da Liberdade in Lisbon.

Aplicação de um método ergonômico para avaliação da permanência e atratividade em espaço público aberto: estudo de caso Parque Vitória Régia, Bauru - SP

There are several researches on evaluation of urban public space, but not all establish a relationship between the configuration of spaces with the thermal environment, ergonomics and environmental behavior of users. To understand this relationship, the aim of this paper is to present the model DEPAN (Design for Permanence and Attractiveness in niches open spaces of conviviality), based on graphical meshes, which were designed to evaluate the influence of design and ergonomics of open public spaces in the human thermal comfort and the ways in which users appropriate the space. Its applicability is demonstrated through a case study conducted in a park in the city of Bauru-SP. To perform this evaluation public space niches were chosen. They were formed by morphological elements and street furniture and defined by their spatial arrangements. The collected data were incorporated into a Geographic Information System (GIS), which allowed the overlay of meshes. The results indicate that the DEPAN model allows the verification of the spatial characteristics, thermal quality and ergonomic design generated by spaces, as well as the evaluation of the influence of these aspects in the way of using the spaces. The model allows the generation of a classification for every niche and set a value for the level of service offered.

Modelo adaptativo de conforto para avaliação in loco de espaços urbanos abertos

Espaços urbanos abertos possibilitam menor controle das variáveis ambientais do que espaços fechados, que apresentam maior grau de confinamento. Por outro lado, as possibilidades de adaptação dos usuários nos espaços abertos acabam sendo maiores devido aos seus usos predominantes. O objetivo deste artigo é verificar possíveis meios de adaptação térmica, tais como atividades, vestimentas e aclimatação, para a proposição de ajustes na Temperatura Equivalente de Globo, que é utilizada para avaliação in loco de espaços urbanos abertos. Foram realizados levantamentos de campo com quantificação de variáveis ambientais e aplicação de questionários, e comparação dos resultados de modelos preditivos e diferentes bases empíricas. O estudo considerou diferentes atividades físicas, diferentes conjuntos de vestimenta e diferentes condições de aclimatação. Os resultados indicaram a necessidade de ampliações na base empírica para os dados relativos às atividades e vestimentas. Com relação à aclimatação, considerando a temperatura do ar média horária dos trinta dias anteriores a que estavam expostos os entrevistados, sua verificação demonstrou que, dentro dos limites do estudo, a abordagem adotada de propor ajustes na Temperatura Equivalente de Globo, é adequada,. Os resultados do modelo ajustado com base nos resultados de aclimatação dos entrevistados apresentaram correlação mais alta com as bases empíricas do que os resultados do modelo originalmente proposto.

Ricerca di criteri analitico-progettuali per la riqualificazione paesaggistica di strutture e infrastrutture in aziende agricole multifunzionali.

Obiettivo generale dello studio è rivolto alla definizione di linee d’indirizzo volte alla riqualificazione paesaggistica, per l’integrazione ed il recupero delle corti e degli edifici moderni dei centri aziendali agricoli a carattere multifunzionale in territorio rurale, attraverso soluzioni appropriate sia sul piano tecnologico-formale che su quello economico-funzionale. Con riferimento ad un’area studio sovracomunale della provincia di Bologna (Regione Emilia-Romagna), si è determinato, quale obiettivo specifico, l’individuazione delle possibili soluzioni di riqualificazione, da realizzarsi in economia, cioè primariamente attraverso i mezzi e le competenze normalmente disponibili in un’azienda agricola di questo tipo. A seguito del riconoscimento dei caratteri specifici e dei tipi edilizi degli edifici rurali tradizionali nella pianura emiliano romagnola, dell’identificazione delle metodologie d’indagine dei caratteri degli edifici rurali in letteratura, nonché dell’analisi della normativa di riferimento in materia di aziende multifunzionali, sono state definite le aziende studio, appartenenti ad aree geografiche differenti. La metodologia d’indagine individuata è stata condotta per la determinazione delle tipologie costruttive, dei materiali utilizzati e dei requisiti delle aziende, in relazione alle diverse specificità, alla definizione funzionale degli spazi costruiti, degli spazi aperti e delle differenti relazioni fra essi e l’identificazione ed analisi dei percorsi delle diverse tipologie di fruitori. L’identificazione delle criticità dei caratteri architettonici riscontrate, sia negli edifici agricoli sia nella corte, ha condotto al riconoscimento degli ambiti di intervento per la progettazione delle soluzioni di riqualificazione funzionale e paesaggistica, attraverso lo studio delle possibili soluzioni per la schermatura o rivalorizzazione sia degli edifici moderni di servizio all’agricoltura (analizzando le potenzialità progettuali offerte dalle pareti verdi, dai brise soleil, dalle facciate ventilate o da intonaci e tinteggiature), sia per la riqualificazione dei percorsi e degli aspetti paesaggistici (intervenendo sulla proposta di materiali da pavimentazione, e delle essenze da utilizzare), da realizzarsi in economia, ma comparati con alternative proposte di tipo commerciale.

Ahmedabad | Laboratorio di architettura moderna Il National Institute of Design (1961-68) fra contatti internazionali ed echi della tradizione

Oggetto della ricerca è lo studio del National Institute of Design (NID), progettato da Gautam Sarabhai e sua sorella Gira, ad Ahmedabad, assunta a paradigma del nuovo corso della politica che il Primo Ministro Nehru espresse nei primi decenni del governo postcoloniale. Obiettivo della tesi è di analizzare il fenomeno che unisce modernità e tradizione in architettura. La modernità indiana, infatti, nacque e si sviluppò con i caratteri di un Giano bifronte: da un lato, la politica del Primo Ministro Nehru favorì lo sviluppo dell’industria e della scienza; dall’altro, la visione di Gandhi mirava alla riscoperta del locale, delle tradizioni e dell’artigianato. Questi orientamenti influenzarono l’architettura postcoloniale. Negli anni ‘50 e ’60 Ahmedabad divenne la culla dell’architettura moderna indiana. Kanvinde, i Sarabhai, Correa, Doshi, Raje trovarono qui le condizioni per costruire la propria identità come progettisti e come intellettuali. I motori che resero possibile questo fermento furono principalmente due: una committenza di imprenditori illuminati, desiderosi di modernizzare la città; la presenza ad Ahmedabad, a partire dal 1951, dei maestri dell’architettura moderna, tra cui i più noti furono Le Corbusier e Kahn, invitati da quella stessa committenza, per la quale realizzarono edifici di notevole rilevanza. Ad Ahmedabad si confrontarono con forza entrambe le visioni dell’India moderna. Lo sforzo maggiore degli architetti indiani si espresse nel tentativo di conciliare i due aspetti, quelli che derivavano dalle influenze internazionali e quelli che provenivano dallo spirito della tradizione. Il progetto del NID è uno dei migliori esempi di questo esercizio di sintesi. Esso recupera nella composizione spaziale la lezione di Wright, Le Corbusier, Kahn, Eames ibridandola con elementi della tradizione indiana. Nell’uso sapiente della struttura modulare e a padiglione, della griglia ordinatrice a base quadrata, dell’integrazione costante fra spazi aperti, natura e architettura affiorano nell’edificio del NID echi di una cultura millenaria.

Transgenerational effects of land use on offspring performance and growth in Trifolium repens

entral European grasslands vary widely in productivity and in mowing and grazing regimes. The resulting differences in competition and heterogeneity among grasslands might have direct effects on plants, but might also affect the growth and morphology of their offspring through maternal effects or adaptive evolution. To test for such transgenerational effects, we grew plants of the clonal herb Trifolium repens from seeds collected in 58 grassland sites differing in productivity and mowing and grazing intensities in different treatments: without competition, with homogeneous competition, and with heterogeneous competition. In the competition-free treatment, T. repens from more productive, less frequently mown, and less intensively grazed sites produced more vegetative offspring, but this was not the case in the other treatments. When grown among or in close proximity to competitors, T. repens plants did not show preferential growth towards open spaces (i.e., no horizontal foraging), but did show strong vertical foraging by petiole elongation. In the homogeneous competition treatment, petiole length increased with the productivity of the parental site, but this was not the case in the heterogeneous competition treatment. Moreover, petiole length increased with mowing frequency and grazing intensity of the parental site in all but the homogeneous competition treatment. In summary, although the expression of differences between plants from sites with different productivities and land-use intensities depended on the experimental treatment, our findings imply that there are transgenerational effects of land use on the morphology and performance of T. repens.

Crecimiento y recubrimiento de Azorella monantha Clos (Apiaceae) en los altos Andes Centrales de Mendoza, Argentina

Azorella monantha Clos (Apiaceae) es una planta en cojín que se desarrolla desde 2900 a 4000 m s.n.m. en los Andes Centrales de Mendoza, Argentina. Su población comprende individuos de diferentes formas y tamaño. Estos cojines muestran alta ocurrencia en sitios llanos y base de laderas donde hasta se superponen formando carpetas o alfombras más o menos continuas. Ellos presentan el fenómeno de recubrimiento al cubrir todos los obstáculos que aparecen en la expansión de sus crecimientos como bloques de piedras, ripio, plantas y hasta sus propios individuos. Estos hechos de recubrimientos señalan la alta capacidad de estos cojines de ocupar los espacios disponibles. En el área estudiada su crecimiento en diámetro lateral fue de 1,15 a 1, 90 cm/año (promedio de 1, 52 cm/año). Observaciones y mediciones de los cojines revelan el carácter agresivo de los mismos sobre los obstáculos y plantas invasoras que temporalmente ocupan los sitios de los espacios vacíos abiertos en sus superficies. Con esto último se demuestra su carácter totalmente opuesto al de una verdadera nodriza como se le atribuye a él y a otros cojines andinos.

Description, geochemistry and mineral composition of ODP Site 193-1189 jasperoids, PACMANUS field

Bright red "jasperoids" were recovered at three positions during Leg 193 drilling below Roman Ruins (Site 1189) in the PACMANUS hydrothermal field. These do not represent fossil exhalative oxide deposits equivalent to those associated with sulfide chimneys at the Roman Ruins seafloor. Rather, they constitute an integral, relatively early stage involving oxidized fluids in the development of veins and breccias that characterize the mostly sulfidic stockwork zone intersected below Roman Ruins in Hole 1189B. They formed by growth of quartz in open spaces created by hydrofracturing, the characteristic feature being mostly euhedral cores dusted by tiny hematite flakes. In one occurrence there are also frondlike aggregates and possible earlier cavity linings of hematite, overgrown by quartz, that potentially formed by maturation of ferruginous gels first deposited in the openings. The trace element geochemistry of the jasperoids, apart from minor enrichment in uranium, provides no indication that they represent subsurface conduits for fluids that deposit Fe-Mn-Si at the seafloor, though this remains a possibility for some such deposits.

Chemistry of various minerals of altered basalts from ODP Hole 111-504B

Basalts recovered from Hole 504B during ODP Leg 111 are more or less altered, but there is no sign of strong shear stress or widespread penetrative deformation; hence, they retain well their primary (igneous) structures and textures. The effect of alteration is recognized as the partial or total replacement of primary minerals (olivine, clinopyroxene, and plagioclase) by secondary minerals and as the development of secondary minerals in open spaces (e.g., veins, fractures, vugs, or breccia matrix). The secondary minerals include zeolite (laumontite and stilbite), prehnite, chlorite, epidote, Plagioclase (albite and/or oligoclase), amphibole (anthophyllite, cummingtonite, actinolite, and hornblende), sodic augite, sphene, talc, anhydrite, chalcopyrite, pyrite, Fe-Ti oxide, and quartz. Selected secondary minerals from several tens of samples were analyzed by means of an electron-probe microanalyzer; the results are presented along with brief considerations of their compositional features. In terms of the model basaltic system, the following two types of low-variance (three-phase) mineral assemblages were observed: prehnite-epidote-laumontite and prehnite-actinolite-epidote; both include chlorite, albite and/or oligoclase, sphene, and quartz. The mineral parageneses delineated by these low-variance mineral assemblages suggest that the metamorphic grade ranges from the zeolite facies to the prehnite-actinolite facies. The common occurrence of prehnite indicates that greenschist facies conditions were not attained even in the deepest level of Hole 504B, which, in a strict sense, contradicts the previous interpretation that the lower portion of Hole 504B suffered greenschist facies alteration.
