13. Efeitos de inibidores de proteinases de soja em organismos não-alvo associados à cultura da cana-de-açúcar / Effects of soybean proteases inhibitors on non-target organisms associated to sugarcane
Genes of plants expressing insect proteinase inhibitors have been introduced into plants for pest control. Proteases inhibitors are present in plant tissues, mainly in seeds, and act in response to predators and pathogens. The Bowman-Birk type and Kunitz type of serine proteases inhibitors (PI) from soybean seeds are been used to increase resistance of sugar

14. Relações entre a mineralogia, fertilidade, acidez e macrofauna em latossolos do cerrado sob pastagem
The Cerrado region occupies approximately 24% of Brazilian territory, making it the second biggest biome in South América, exceeded only by the Amazon Rainforest. The majority of the soils of the region were described as being acid, with a low capacity for cation exchange and high saturation by aluminium. Pastures cover 117 million hectares, of which 54 mil

15. Residuos da construção civil : analise de usinas de reciclagem / Residues generated by the constructive : ativities recycling plants
This work is an approach to the development for sustentability in the sector of the Civil Construction, focusing the residues generated by the constructive activities and its use in the recycled aggregates production. As the production process in the construction industry is based on a lineal model is unviable, it degrades the middle-atmosphere and they cont

16. Study of method to characterize the physical properties of construction and demolition waste coarse aggregates. / Estudo de métodos para caracterização de propriedades físicas de agregados graúdos de resíduos de construção e demolição reciclados.
The low consumption of Construction and Demolition Waste (CDW) recycled aggregates happens, nowadays, because its natural variability and quality control absence that limit its use in applications with larger demands, such as concretes. One way of concrete aggregates control is done by determining its porosity, express by physical properties absorption and r

17. Treatment of the chromium-containing solid wastes from leather industry: use in adsorption process and as nitrogen source in agriculture. / Tratamento de rejeitos sÃlidos contendo cromo da indÃstria de couro: uso em processos de adsorÃÃo e como fonte de nitrogÃnio na agricultura.
The leather industry has a great economic importance for Brazil, however it is responsible for the generation of solid wastes containing chromium (sawdust and stripes of wet blue leather), which need suitable disposal for being classified as class 1 waste. The objectives of this work were to treat this waste for chromium removal and to use the resultant mate

18. Compostagem e solarizaÃÃo para higienizaÃÃo de lodo de esgoto e uso no cultivo de CÃsia Amarela (Senna Siamea Lam)
The sewage sludge is the main waste produced in Wastewater Treatment Plants (WTPs). Itâs final destination called the attention of several govenmental agencies and research intitutions. Proper disposition of sewage sludge is fundamental in order to avoid potential environmental damages. The beneficial use of sludge in agriculture, has well established pract

19. Influência do lodo de esgoto na nodulação e no desenvolvimento do Caupi (Vigna unguiculata "L" Walp)
The intense urban growth, production of domestic and industrial residues has been increased, mainly sewage sludge. This residue has high amount of pathogenic organisms and heavy metals. The viable alternative for this residue destination is its use in agriculture improving the chemical, physical and biological soil characteristics. Allied of the capacity of

20. Caracterização tecnológica de resíduos de construção e demolição. / Technological characterization of construction and demolition waste.
Construction and demolition waste (CDW) represents around 50% of the total solid waste and are essentially constituted by mineral fraction (>90%); therefore it?s possible to recycle it through mineral processing techniques. The development of different uses and the improvement of the typical technologies applied to CDW recycling are essential to achieve a sa

21. Evaluation of potential usage of a concentrate blast furnace sludge as source of zinc for rice (Oryza sativa L.) crop / Avaliação do potencial de uso do resíduo lama concentrada de altos-fornos como fonte de zinco em cultura de arroz (Oryza sativa L.).
This study was done in a greenhouse at the Universidade Federal Rural do Rio de Janeiro campus, and it was initiated on April, 2005 and completed on March, 2006. The objective was to verify the effects of an addition of a steelmaking waste from a zinc concentration process, to establish if the element zinc was delivered in sufficient quantity to a good plant

22. Caracterização de agregados de resíduos de construção e demolição reciclados e a influência de suas características no comportamento de concretos. / Characterisation of recycled aggregates from construction and demolition waste and the influence of their characteristics on concrete mechanical performance.
Construction and demolition waste (CDW) recycled aggregates are not largely used in concrete due to CDW composition heterogeneity and CDW recycled aggregate physical property variability from visual classification and hand sorting of proposed standards that provide insufficient relation between the aggregate characteristics and concrete performance. This the

23. Ciclagem de nutrientes após aplicação de lodo de esgoto (Biossólido) sobre latossolo cultivado com Eucalyptus grandis / Nutrients cycling after sewage sludge (biosolid) apllication on oxisol planted with Eucalyptus Grandis
The treatment of wastewaters generates the sewage sludge, a residue that could be used to increase the productivity of both farming and forest plantations. The general aim of this work was to evaluate how biosolid affects the biogeochemistry of nutrients at an Eucalyptus grandis plantation. The study site is at the Experimental Station of Itatinga, linked to

24. Study on the possibilities of recycling of wastewater treatment wastes generated in the Metropolitan Region of São Paulo. / Estudo das possibilidades de reciclagem dos resíduos de tratamento de esgoto da Região Metropolitana de São Paulo.
The objective of this work was to investigate the options for the management of wastes generated from wastewater treatment plants, which were technically, environmentally, socially and economically feasible. The wastewater treatment process generates non-inert solid wastes among which the sludge is the most significant due to the amount produced. In the Metr
