Diagnóstico dos resíduos de construção e demolição para elaboração e implantação da gestão integrada dos RCD no município de Guanambi – BA

Taking as starting the environmental, social and economic impact of construction and demolition waste in Brazilian cities were created legal mechanisms for management and administration, seeking to minimize the impacts to the maximum, since the irregular deposition can be characterized as environmental crime. CONAMA Resolution No. 307 of 2002 establishing the mandatory implementation of an Integrated Management System Construction Waste and Demolition, guiding the classification and designation of the waste generating agents, collection agents and transporters, and the areas of culling and disposal of waste. The technical partnership between the Ministry of Cities, the Environment Ministry and the Caixa Econômica Federal, coordinated by Pinto & Gonzales (2005) Management in the work and management of construction waste, proposed a guidance manual to guide the implementation of a System Integrated Management of Construction Waste in Municipalities. The municipality of Guanambi in the state of Bahia, in full economic rise, lacks a waste management of construction and demolition, since there has areas for the disposal of waste being proposed in this paper the diagnosis of waste generation in the municipality as part of the methodology proposed by the work of Pinto & Gonzales (2005).

Plano de gerenciamento sustentável dos resíduos de construção civil. O caso de Rio Claro (SP)

The current problematic of the construction and demolition (C&D) waste faced for the Brazilian cities, is one of the main degradation factors of the environment, over all about the promise of the urban ambient quality. This scenery must mainly to the unsustainable management adopted by the great majority of the Brazilian cities. Therefore, this work aims at to offer subsidies for medium cities, having as study object the city of Rio Claro-SP, (Brazil), in the elaboration of plans and integrated programs of sustainable management of the construction and demolition waste, in accordance with CONAMA Resolution nº 307/2002, that’s set up a sustainable management system of C&D waste. In this direction, the diagnosis of the management was elaborated for the city of Rio Claro, (generation, collects, transport and disposal) and the public administration of the construction and demolition waste, as well as of the study of the related aspects with C&D waste recycling plant. Later, was suggested a plan of improvements for the public manager of C&D waste: areas of temporary disposal to facility the appropriating destination, appropriated areas of final disposal, incentives to the recycling of C&D waste, new legislations, education and orientation programs and adequacy the agents of C&D waste management (generating, transporting, addressee and public manager), directing for an environmental, economic and social sustainability.

Análise sobre a importância do gerenciamento de resíduos de construção e demolição na universidade

With the growth of settlements and the consequent rise in civilian buildings, there was a need to allocate appropriately the waste arising from construction and demolition. Failure to meet the standards set about building waste generate social, economic and environmental impacts of remediation difficult. This study aimed to attend the importance of holding management programs involving the waste of construction and demolition at the University by the resulting environmental, economic and social benefits, and analysis of the main stages of Waste Management of Construction and Demolition, whose based on the National Solid Waste Policy, as well as verification of the importance of implementing these steps in the design of works, assisting in future studies of this type of waste and the problems accompanying the University

Wastes released by tanneries at Patrocinio Paulista, São Paulo State, Brazil

This investigation was carried out within the Parana sedimentary basin, Brazil, and involved the sampling of sludge and residuary waters that were collected from reservoirs/decantation ponds settled in two tanneries situated at Patrocinio Paulista, São Paulo State Two samples from each tannery were collected, stored in appropriate flasks and transported to the LABIDRO for chemical analysis The LABIDRO (Laboratory of Isotopes and Hydrochemistry) of the Petrology Department at the Geosciences and Exacts Sciences Institute of UNESP is situated in Rio Claro city, about 240 km distant from the investigated area The data for residuary waters were compared with guideline values established by two different legislations (a) Rule No 12486 (NTA60) established in 20(th) October 1978 by São Paulo State for defining the potable water standards and (b) Register 997 published on 31 May 1976 that defines the permissible concentration limits in effluents to be released to water bodies (coastal, fresh or ground water) in São Paulo State The results confirmed that leather production is an activity with high environmental impact, despite improvements that may be achieved by tanneries

Measurement of fats, oil and grease by spectro-photometry and its application on different sites at São Paulo State, Brazil

This investigation was carried out within the Parana sedimentary basin, Brazil, involved the sampling of effluents and groundwater from monitoring stations situated at different sites at São Paulo State, and was realized with the purpose of evaluating the presence of fats, oil and grease (FOG) in different matrices. Several tests were realized with very distinct materials (cooking oil, butter, margarine, pig fat, vacuum pump oil) in order to properly calibrate the spectrophotometric system. Each matrix was dissolved with 1,1,1-trichloroethane and from the stock solutions it was prepared working standards from different dilutions. The data obtained were plotted on absorbance vs. concentration graph that yielded a successful calibration curve when a mineral oil for vacuum pump was utilized in the experiments at a wavelength corresponding to 410 mn. The results obtained for the analyzed samples were compared with the limiting value established by the São Paulo State legislation on the prevention and pollution control of the environment that was established in 8(th) September 1976 by Rule No. 8468.

Desempenho operacional e ambiental de unidades de reciclagem e disposição final de resíduos sólidos domésticos financiadas pelo ICMS Ecológico de Minas Gerais

Este estudo avalia sistemas de reciclagem e de disposição de resíduos sólidos domésticos que possuem incentivos fiscais definidos pela Lei Estadual nº 13.803/2000 de Minas Gerais. A pesquisa foi desenvolvida por análise de documentação de licenciamento ambiental de aterros sanitários e usinas de reciclagem e compostagem de resíduos financiados pela referida Lei e por visitas às unidades sanitárias, sendo usados os instrumentos metodológicos da agência ambiental do Estado de São Paulo (CETESB) que avaliam as condições de instalação e operação desses tipos de empreendimentos. do estudo, constatou-se que o incentivo de Minas Gerais, definido pela Lei do ICMS Ecológico, traz importantes benefícios ambientais aos municípios, embora ainda seja reduzido o número dos contemplados por esse fomento à gestão dos resíduos sólidos urbanos. Conclui-se, também, que algumas das unidades estudadas apresentam problemas de natureza ambiental e operacional.

Centrex: uma proposta de sistema de forças ortodônticas para atuação no centro de resistência

OBJETIVO: este trabalho propõe um novo sistema de forças ortodônticas que visa eliminar ou diminuir alguns efeitos secundários da mecânica ortodôntica, como as inclinações, extrusões e perdas de ancoragem. Por meio de uma revisão crítica da literatura sobre a biomecânica, e de ilustrações detalhadas dos mecanismos, procura-se apresentar didaticamente o seu conceito e sua proposta de funcionamento. CONCLUSÕES: embora já existam outras tentativas de diminuir efeitos indesejados da mecânica ortodôntica, como o Power-arm de Andrews e a mecânica com arcos segmentados, ainda assim, sua utilização tem se mostrado muito distante de uma unanimidade na prática clínica ortodôntica. O Centrex talvez se mostre como uma forma de melhorar a mecânica ortodôntica pela diminuição de alguns efeitos indesejados.

Nest architecture of the leaf-cutting ant Acromyrmex rugosus rugosus

The prominent nests mounds of many ant species are one of the most obvious signs of their presence, yet the subterranean architecture of nests is often poorly known. The present work aimed to establish the external and internal structure of nests of a species of leaf-cutting ant, Acromyrmex rugosus rugosus, by either marking the interior of nests with talcum powder, or forming casts with cement. Twelve nests were excavated and surveyed, with eight being marked with talcum powder and four cast with cement. The external and internal structure of the nests was highly variable. The largest and smallest nests had mound areas of 9.89 m(2) and 0.01 m(2) respectively. The number of chambers found ranged from I to 26, with maximum dimensions of between 6 and 70 cm. Chambers were found close to the soil surface (6 cm) down to a maximum depth of 3.75 m. In addition to chambers containing fungus garden, some chambers were found to be empty, filled with soil or filled with waste, the first time this has been recorded in a species of Acromyrmex. The nests of A. rugosus rugosus appear to be unusually complex for the genus, containing a diversity of irregular chambers and tunnels.
