Arquitetura industrial no Brasil

Este estudo faz parte da pesquisa de doutoramento e se enquadra no âmbito da Arquitetura Industrial e seu patrimônio edificado. Tem como objetivo estudar casos de reuso de indústrias que possam fazer referência ao patrimônio industrial da cidade de Panambi-RS-Brasil, trazendo estratégias de projeto arquitetônico aplicadas a áreas industriais inseridas no contexto urbano e que se encontram em desuso, tanto na cidade de Panambi como em outras cidades brasileiras. Para tal, propõe-se o estudo de três casos de projetos de reabilitação de áreas industriais, respectivamente nas cidades de São Paulo (Capital), Piracicaba (São Paulo) e Ilópolis (Rio Grande do Sul). O estudo se dá a partir de pesquisa bibliográfica, visita aos locais de estudo e levantamento fotográfico. Pretende-se, com este estudo, estabelecer as metodologias de projeto arquitetônico aplicadas a essas edificações industriais e, sobretudo, compreender as estratégias de projeto para a recuperação dessas áreas. Promover a recuperação dessas edificações e do seu entorno urbano melhora a qualidade de vida, bem como preserva o patrimônio industrial e a paisagem urbana dessas cidades. Em consequência, a cidade de Panambi-RS-Brasil torna-se referência em casos de reuso do patrimônio industrial.This work is part of the doctoral research and falls within the scope of industrial architecture and its built heritage. Its objective is to study cases of reuse of industries that may be a reference to the industrial patrimony of the city of Panambi-RS-Brazil. Bringing architectural design strategies applied to industrial areas inserted in the urban context and that are in disuse, both in the city of Panambi and in other Brazilian cities. For that, it is proposed the study of three cases of rehabilitation projects of industrial areas, in the cities of São Paulo (São Paulo), Piracicaba (São Paulo) and Ilópolis (Rio Grande do Sul). The study will be based on bibliographic research, visits to study sites, and photographic survey. The purpose of this study is to establish the architectural design methodologies applied to these industrial buildings and, above all, to understand the design strategies for the recovery of these areas. Promoting the recovery of these buildings and their urban surroundings, improving the quality of life as well as preserving the industrial heritage and the urban landscape of these cities, becoming a reference to cases of reuse of the industrial heritage in the city of Panambi-RS-Brasil

Sialylglycoconjugates and sialyltransferase activity in the fungus Cryptococcus neoformans

Cryptococcus neoformans is a fungal pathogen associated with systemic mycoses in up to 10% of AIDS patients. C. neoformans yeasts express sialic acids on the cell wall, where they play an anti-phagocytic role, and may represent a virulence factor at the initial phase of infection. Since the nature of the sialic acid-carrying components is undefined in C. neoformans, our aim in the present work was to identify sialylated molecules in this fungus and study the sialylation process. C. neoformans yeast forms were cultivated in a chemically defined medium free of sialic acids, to search for autologous sialylglycoconjugates. Sialylated glycolipids were not detected. Two glycoproteins with molecular masses of 38 and 67 kDa were recognized by Sambucus nigra agglutinin, an alpha2,6-sialic acid-specific lectin. the 67 kDa glycoprotein also interacted with Influenza C virus, but not with Limax flavus agglutinin, suggesting the presence of the 9-O-acetylated sialic acid derivative as a constituent of the oligosaccharide chains. A partially purified protein fraction from cryptococcal yeast forms was able to transfer sialic acid from CMP-Neu5Ac to both N-(acetyl-1-C-14)-lactosamine and asialofetuin. Additional evidence for a sialyltransferase in C. neoformans was obtained through the reactivity of fungal proteins with rabbit anti-rat alpha2,6 sialyltransferase polyclonal antibody. Our results indicate that sialic acids in C. neoformans are linked to glycoproteins, which are sialylated by the action of a fungal sialyltransferase. This is the first demonstration of this biosynthetic step in pathogenic fungi.

Climate-Based Analysis for the Potential Use of Coconut Oil as Phase Change Material in Buildings

One of the most efficient measures to reduce energy consumption in buildings is using passive thermal comfort strategies. This paper shows the potential of coconut oil as a bio-based phase change material (PCM) incorporated into construction components to improve the thermal performance of buildings for several climates, due to its environmental advantages, wide availability, and economic feasibility. The thermophysical properties of coconut oil were determined through differential scanning calorimetry. Numerical simulations were conducted in ESP-r, comparing an office space with a gypsum ceiling to one with coconut oil as PCM for 12 climate types in the Köppen– Geiger classification. The results show that coconut oil is a suitable PCM for construction applications under tropical and subtropical climates. This PCM can provide year-round benefits for these climates, even though a higher melting point is needed for optimum performance during hotter months. The highest demand reduction of 32% and a maximum temperature reduction of 3.7 °C were found in Mansa, Zambia (Cwa climate). The best results occur when average outdoor temperatures are within the temperature range of phase change. The higher the diurnal temperature range, the better the results. Our findings contribute to a better understanding of coconut oil in terms of its properties and potential for application in the building sector as PCM
