Sustainable Methods and Techniques in Old and New Public Constructions

Journal of Civil Engineering and Architecture 2013年第11期7卷 1433-1444页

This article is about the methods and techniques used in the building ＂retrofit＂ in modernist style designed by the architect Affonso Eduardo Reidy in the fifties, and also about the project of the new Rio de Janeiro MIS （Museum of Image and Sound）, under construction, by The North-American office Diller Scofidio ＋ Renfro, both located in the city of Rio de Janeiro. These constructions present a wide view of the concept of sustainability, not commonly used in public buildings in Brazil. In the building designed by Reidy, which belongs to the State of Rio de Janeiro, the regeneration to host the new headquarters of the State Department of Taxation and Finance respected its original characteristics and used smart and sustainable design techniques, as well as recyclable materials. On the other hand, the project of the new museum at Copacabana Beach was entirely planned on sustainable bases and it includes the application of building techniques concerning that purpose. This article presents a study of these two cases and evaluates the techniques and materials used in one another. Observing the principles of sustainability in construction is a pioneering initiative of the State Government. This article aims at making the scientific community aware of the needs of immediate adoption of sustainability techniques in Civil Engineering, not only in the construction of new buildings, but also in the regeneration of the existing ones, as well as the need of imperious adoption of sustainable techniques when it comes to maintainability.

Risk Analysis： A Methodology Applicable to the Building Inspection

引用

Journal of Civil Engineering and Architecture 2016年第9期10卷 1052-1058页

作者： mauricio noya Ana Lucia Torres Seroa da Motta Mariangela Moura Rafael Carvalho de Souza Bruno Barzellay Programa de Pos-graduacao em Engenharia Civil Universidade Federal Fluminense Rio de Janeiro 22211-200 Brazil Departamento de Engenharia Civil da Universidade Federal do Rio de Janeiro-Campus Macae Rio de Janeiro 22211-200 Brasil

The lack of care related to maintenance management is directly linked to the absence of plans for maintenance of buildings. Because of that, there is a big incidence of building accidents caused by the negligence of managers and the lack of investment. The research has shown that, although building inspection is a consolidated building maintenance tool, managers do not prepare their building maintenance plan, nor use building inspection as a tool, leading the buildings to the premature obsolescence. The research calls attention to the building inspection technique that can be used to evaluate building maintenance and conservation. It is also a tool for analysis and investment planning based on actions to solve failures and anomalies that might come out during the building inspection. Those failures and anomalies are classified according to their degree of risk, determining the technical priorities of the investment adjustment in the maintenance plan. The paper presents a risk analysis methodology which classifies inspect elements in a building, determining the priority order of services to be executed on a scale from minimum risk （1） to imminent risk （5）. The method shows a tool for building inspection, and it serves as a guideline for building maintenance interventions.

Fecal samples or cloacal swabs are preferred over lethal dissections to study vertebrate gut microbiota for ethical reasons,but it remains unclear which nonlethal methods provide more accurate information about gut *** compared the bacterial communities of three gastrointestinal tract(GIT)segments,that is,stomach,small intestine(midgut),and rectum(hindgut)with the bacterial communities of the cloaca and feces in the mesquite lizard Sceloporus *** hindgut had the highest taxonomic and functional alpha diversity,followed by midgut and feces,whereas the stomach and cloaca showed the lowest *** taxonomic assemblages of the GIT segments at the phylum level were strongly correlated with those retrieved from feces and cloacal swabs(rs>0.84 in all cases).The turnover ratio of Amplicon Sequence Variants(ASVs)between midgut and hindgut and the feces was lower than the ratio between these segments and the *** than half of the core-ASVs in the midgut(24 of 32)and hindgut(58 of 97)were also found in feces,while less than 5 were found in the *** the ASVs level,however,the structure of the bacterial communities of the midgut and hindgut were similar to those detected in feces and *** findings suggest that fecal samples and cloacal swabs of spiny lizards provide a good approximation of the taxonomic assemblages and beta diversity of midgut and hindgut microbiota,while feces better represent the bacterial communities of the intestinal segments at a single nucleotide variation level than cloacal swabs.
