1. Nucleação na formação de estruvita: estado da arte
RESUMO Estimativas recentes indicam que a duração de toda a reserva de rochas fosfatadas do planeta não ultrapassa 400 anos e que a produção de fertilizantes nitrogenados é insustentável energeticamente. Atualmente, o tratamento de esgoto está sendo visto como uma unidade de recuperação de recursos (água, energia e nutrientes) em vez de uma de fin

2. PROJECT SCHEDULING OPTIMIZATION IN ELECTRICAL POWER UTILITIES
The problem of choosing from a set of projects which ones should be executed and whenthey should start, depending on several restrictions involving project costs, risks, limited resources, dependencies among projects, and aiming at different, even conflicting, goals is known as the project portfolio selection (PPS) problem. We study a particular version of t

3. Cerrado e Ameaças as Pontecialidade: Caracterização etnobotânica da vegetação remanescente do município de Goiandira (GO) / Cerrado e Ameaças as Pontecialidade: Caracterização etnobotânica da vegetação remanescente do município de Goiandira (GO) / Cerrado and the Potential Threats: ethnobotany characterization of remnant vegetation in the muncipality of Goiandira (GO) / Cerrado and the Potential Threats: ethnobotany characterization of remnant vegetation in the muncipality of Goiandira (GO)
O estudo sobre o Cerrado e Potencialidades visa a contribuir com o aumento da informação a respeito da vegetação do Cerrado pela compreensão da apropriação da natureza, conhecendo a relação que há entre o homem e a vegetação por meio do levantamento etnobotânico das áreas atingidas parcialmente pela PCH Goiandira. A metodologia de pesquisa base

4. Remoção de sulfeto de hidrogênio, ferro e manganês de águas de abastecimento através dos processos de dessorção gasosa, nanofiltração e oxidação com permanganato de potássio
Many regions in Brazil have problems associated with the water quality of their supplies, which bring problems to the production of safe drinking water that is distributed in communities. Generally, consumers judge the drinking water safety through the use of their organoleptic senses. The conventional processes used in water treatment are not effective to r

5. Analise dos sistemas de proteção e controle de instalações industriais com geradores sincronos durante operação ilhada / Protection and control systems analysis of industrial plants with synchronous generators during islanded operation
Modern industrial systems are very sophisticated installations with a high number of automatic processes and capability of isolated (islanded) operation after contingences by using onsite generators composed mainly by synchronous machines and steam turbines. Such installations, in the presence of generators, are generically called autoproducers. Since many o

6. Alteration in the composition of cell wall polysaccharides in Nicotina tabacum by modulating the expression of the uxs gene, coding for UDP-D-glucuronic acid decarboxylase enzyme (EC 4.1.1.35) / Alteração da composição dos polissacarídeos da parede celular de Nicotiana tabacum, pela modulação da expressão do gene uxs que codifica a enzima UDP-D-glucuronato descarboxilase (EC 4.1.1.35)
The plant cell wall is not only an essential structure for plants, but also an extremely important raw material in human economy. The plant cell wall has diverse utilities, for example, papermaking, textile fiber, civil construction. Polysaccharides, such as cellulose, hemicelluloses and pectins, are the major components of the primary plant cell wall (appro

7. Avaliação de arranjos cogeradores em siderurgicas brasileiras com auxilio de simulação computacional
This work deals with technical and economical assessment of cogeneration schemes ir Brazilian steel industries based on cogeneration plants previously installed in Brazil and abroad In particular, cogeneration schemes that can cover 100 per cent of eletric demand and eventuall) produce surplus eletricity, are considered. Computational simulation is used as a

8. Power Generation and the Environment
Environmental factors will play an ever-increasing role in planning for the location and design of future power generating plants. This planning must include all phases of furnishing electric power, such as the exploration for and mining of fossil and nuclear fuels; the transportation and storage of these fuels; power plant siting; the disposal of solid wast

9. Giardia and Cryptosporidium spp. in filtered drinking water supplies.
Giardia and Cryptosporidium levels were determined by using a combined immunofluorescence test for filtered drinking water samples collected from 66 surface water treatment plants in 14 states and 1 Canadian province. Giardia cysts were detected in 17% of the 83 filtered water effluents. Cryptosporidium oocysts, were observed in 27% of the drinking water sam

10. Occurrence of Giardia and Cryptosporidium spp. in surface water supplies.
Giardia and Cryptosporidium levels were determined by using a combined immunofluorescence test for source waters of 66 surface water treatment plants in 14 states and 1 Canadian province. The results showed that cysts and oocysts were widely dispersed in the aquatic environment. Giardia spp. were detected in 81% of the raw water samples. Cryptosporidium spp.

11. Modification of the substrate specificity of an acyl-acyl carrier protein thioesterase by protein engineering.
The plant acyl-acyl carrier protein (ACP) thioesterases (TEs) are of biochemical interest because of their roles in fatty acid synthesis and their utilities in the bioengineering of plant seed oils. When the FatB1 cDNA encoding a 12:0-ACP TE (Uc FatB1) from California bay, Umbellularia californica (Uc) was expressed in Escherichia coli and in developing oils
