1. Effect of the chemical attack on the properties of cimentititous composites with partial substitution of ash from sugar cane bagasse in natura
ABSTRACT Seeking the reutilization of waste from agriculture and urban sources, studies have presented an option in the inclusion of such waste into new low-cost materials that are environmentally viable. One possibility is the reutilization of sugarcane bagasse ashes (SBA), the final waste in the productive process of the Brazilian alcohol sector. In additi

2. Reutilização de efluente de tingimentos de fibras acrílicas pós-tratamento fotoeletroquímico
On a laboratory scale effluents were produced from bichromic dyeing of acrylic fabrics with the basic dyes Blue Astrazon FGGL 300% and Yellow Gold Astrazon GL 200%. The residual dyeing baths were subjected to a photoelectrochemical treatment and reused in a second dyeing process. In the reutilization study, dyeings with treated effluent were compared with st

3. Medidas não convencionais de reservação dágua e controle da poluição hídrica em lotes domiciliares / Unconventional measures of reservoir water and control water pollution in urban lots
This paper aims to analyze the reduction of hydropollution through monitoring non conventional reservation of water applied in urban lots starting from individual and global efficiency integrated to the lot. It also prioritizes the monitoring of both quality and quantity of pollution and the rain flow from its draining. The inclusion of these measurements on

4. Desempenho mecÃnico do solo condicionado com lodo de esgoto calcinado / Mechanical performance of the soil conditioned with burned sewage sludge
Amongst the global problems that most rouse studies and solutions before the environment crisis arise the ones concerning the destination of waste and the sewage system. The sustainable development requires the creation of solutions aiming the reduction or the elimination of the impacts on the environment. The waste may become an Engineering solution. The ai

6. Estimativa da área e do tempo de permanência da vegetação secundária na amazônia legal por meio de imagens LANDSAT/TM
- Secondary vegetation, formed by natural regeneration of areas that are deforested and later abandoned, have many functions relevant to the ecology of the landscape in which it is embedded such as fixation of atmospheric carbon, maintenance of the biodiversity and the connection among forest remnants and restoration of soil fertility. The latter function is

7. Inserção C-H de carbenóides de ródio em água e reutilização do catalisador
A five-session laboratory experiment is described for the synthesis of a beta-lactam via Rh(II) catalysed intramolecular C-H insertion of a alpha-diazo-alpha-ethoxycarbonylacetamide. The metallo-carbene, responsible for the C-H bond activation, was generated from the diazo substrate and the catalyst Rh2(OAc)4. The high stability and solubility of the catalys

8. Desenvolvimento de cerâmica vermelha utilizando rejeitos da construção civil
The Industry of the Civil Construction has been one of the sectors that most contribute to the pollution of the environment, due to the great amount of residues generated by the construction, demolition and the extraction of raw material. As a way of minimizing the environmental impacts generated by this industry, some governmental organizations have elabora

9. Reuso de soluções de corantes básicos, pós-tratamento fotoeletroquímico, para tingimentos de fibras acrílicas
The increasing contamination of natural water resources is gaining public attention and has roused environmental concern in the society. As the second richest country in water resources, Brazil has an abundant supply of water, but it lacks a good management plan for these resources. It is estimated that by 2025, the industry will be responsible for 24% of th

12. "Desenvolvimento de eletrodos de troca iônica eletroquímica para o tratamento de rejeitos contendo íons Cromo ou Césio" / DEVELOPMENT OF ELECTROCHEMICAL ION EXCHANGE ELECTRODES FOR THE TREATMENT OF WASTES CONTAINING CHROMIUM OR CESIUM IONS
Nowadays, environmental preservation using technologies that do not attack it, generating non-toxic residues and reduced volumes, has been discussed. Hazardous effluents, containing metals, as chromium, have been poured in the soils and rivers, degrading the water. Not different are the problems originated from some nuclear activities that generate wastes, a
